Any significant incidents that occur during an operation must be logged. If necessary, incidents
must be reported to the CAA using the guidance in CAP 382 (Mandatory Occurrence
Reporting). With reference to Section 6 Chapter 5 of CAP 722 it is important that all incidents
that occur during flight are logged and, if necessary reported to the CAA, using the contact
details in Chapter 5 of CAP 722.
Incidents that are likely to need reporting include "any incident which endangers or which, if
not corrected, would endanger an aircraft, its occupants or any other person"
Examples are included in CAP 382 "The Mandatory Occurrence Reporting Scheme" and EU
2015/1018 Annex 5. In short, any occurrence relating to the UAS operation that results in
injury or the potential of injury to crew members, client or members of the public should be
reported. Any occurrence resulting in a collision or near miss with another aircraft should be
reported.
Reporting can be completed through the ECCAIRS system at: http://www.aviationreporting.eu
A14: Flight team composition
For most operations, the flight team will compose of the RP. If correctly briefed, any person(s)
judged competent by the RP may act as Observer/Crew.
Version 2.1 Swansea University Operations Manual
DTOM4.6 29/01/2020
The role of the Observer/Crew will be directed by the RP and will depend on the circumstances
of the operation. Observer/Crew, when used, must be briefed by the RP before the first flight
of the operation in accordance with the appropriate QRH.
If a Payload Operator is used, they must be fully briefed in the failsafe systems of the UAS
and how to initiate failsafe in the event of the RP becoming incapacitated. The Payload
Operator must follow the instructions of the RP. They may give instructions to the RP to enable
them to obtain the data they require; it is the responsibility of the RP to ensure that manoeuvres
requested by the Payload Operator are able to be safely carried out.
A15: Operation of multiple UAS
If multiple aircraft are flown during a single operation, a RP must be nominated to have
oversight of the operation and each aircraft must have a dedicated Remote Pilot.
A16: Crew competency requirements
All Remote Pilots must have evidence of theoretical competency and practical competency for
the type of aircraft they are operating. RPs must operate only in accordance with The SUA
Operator's PfCO (see Appendix D). RPs must have completed familiarisation training on the
use of the UAS, to ensure familiarity with all settings and failsafe options.
A17: Crew Health
If any member of crew does not feel they are fit for operations then they must inform the RP
as soon as possible. If the RP does not feel physically and mentally fit to carry out flights then
the operation must be postponed. The RP must not operate the UAS under the influence of
alcohol or recreational drugs. If necessary, medical advice should be obtained before
operating the UAS whilst using prescription drugs.
A18: Logs and records
Logs and records should be kept to ensure compliance with the PfCO.
The Site survey and risk assessment (Appendix B) must be completed by the RP. This
includes site information and survey, operational details, risk assessment and permissions.
A log must be maintained giving details of flight times, RP, UAS and incidents. Online logging
is acceptable as long as it records the above details.
Version 2.1 Swansea University Operations Manual
DTOM4.6 29/01/2020
PART B: OPERATING PROCEDURES
B1: Flight planning and preparation
The tasks in B1 should be ideally carried out before the day of the operation and may need
significant time to implement depending on the complexity of the operation.
B1.1: Determination of the intended tasks and feasibility
Feasibility of all potential operations should be assessed against:
1. The current PfCO
2. The operational envelope of the UAS (see QRH)
3. Other applicable legislation
B1.2: Operating site location and assessment
The RP must carry out a site survey and risk assessment as detailed in appendix B. The
operation must not proceed until all relevant areas have been completed.
B1.3: Risk management
A full risk assessment must be completed using the procedure in appendix B. This should be
as specific to the site as possible. Whilst there is always a degree of acceptable risk, this
should be minimized to ensure the operation is as safe as possible.
B1.4: Advance communications
Relevant authorities and other relevant local bodies who need to advised of the operation to
be identified in appendix B.
B1.5: Airspace check and pre-notification
During the completion of the site survey and risk assessment it should be established if the
operation falls into controlled airspace, flight restriction zones or prohibited, restricted or
danger areas. If necessary, the relevant ATC, local authorities and the Police should be
contacted and provided with contact details to prevent issues during the operation. ATC, FIS
or aerodrome operator permission may be required for flights in Flight Restriction Zones and
Runway Protection Zones as detailed in CAP 1763 and articles 94A and 94B of the ANO.
B1.6: Site permission
Before commencing the operation, the Remote Pilot must be satisfied that all relevant
permissions have been obtained. RPs must be aware of their responsibilities regarding
operations from private land and any requirements to obtain the appropriate permission before
operating from a particular site. In particular, they must ensure that they observe the relevant
trespass laws and do not unwittingly commit a trespass whilst conducting a flight.
Version 2.1 Swansea University Operations Manual
DTOM4.6 29/01/2020
B1.7: Advance weather check
Detailed weather forecasts ideally should be checked before the day of the operation. If necessary, the flight should be postponed. Even if the operation involves a fixed-date event the RP should not feel pressured to continue if it is felt that safety is being compromised. Weather should be checked using an appropriate and accurate weather service.
B1.8: NOTAM check
NOTAMs should be checked using www.notaminfo.com or an appropriate app. Any relevant
NOTAMs should be noted and, if necessary, clarified with local ATC.
B1.9: Preparation and serviceability of equipment and UAS
The pre-deployment checklist in section F6 of the aircraft QRH should be used to ensure the
equipment has been fully checked prior to commencing the operation.
B2: On Site Procedures and Pre-flight Checks
Section B2 involves the use of Appendix B along with the checklists in the aircraft QRH.
B2.1: Site survey
A site survey should be carried out to confirm the findings of the initial risk assessment. Any
additional hazards should be identified and included in the risk assessment. Access should
be agreed and areas identified for parking, equipment assembly and launch.
B2.2: Selection of operating area and alternate landing areas
A safe launch area should be identified and the RTH area for the UAS cleared and, if
necessary, marked to avoid people entering it. An area appropriate to the UAS take-off and
landing requirements (minimum 3 metres) around the take-off point should be identified and,
if necessary, cordoned appropriately. It may be appropriate to use existing boundaries (e.g.
fences) as part of this cordon.
The RP should clearly identify the operating area and any safe alternative landing areas.
B2.3: Observer/Crew briefing
Any Observer/Crew and, if appropriate, persons who are to be under the control of the RP
must be briefed on site by the RP before the first flight of the operation in accordance with the
appropriate QRH. This should include final allocation of roles, a synopsis of the flight and
emergency procedures. If persons under control of the RP are to be overflown they must be
made aware of what to do in the event of a loss of control of the aircraft.
B2.4: Cordon procedure
In the event of an operation that involves members of the public it is best practice to use at
least one member of Observer/Crew. If it is possible to cordon a launch area this may be done
using appropriate materials. At launch the UAS must be at least 30 metres from any person
not under control of the RP and after launch, 50 metres. If a cordon is not used, sufficient crew
must be employed to maintain the landing areas clear at all times.
Version 2.1 Swansea University Operations Manual
DTOM4.6 29/01/2020
The Observer/Crew should ensure that members of the public do not enter the landing area
and that the RP is not disturbed during flight.
B2.5: Operational Communications
If appropriate, communications should be maintained with local ATC. It is best practice to notify
the ATC before the operation and after all flights are complete.
Communications with Observer/Crew will normally take place face to face. If the distance
between crew members is too great to facilitate this, an appropriate and legal two-way radio
system must be used.
B2.6: Final weather checks
The RP and any Observer/Crew should be vigilant for any changes in weather which should
be checked on the day of operation using an appropriate and accurate weather service. A final
wind speed check should be carried out using an anemometer if appropriate.
B2.7: Battery changes and charging
Batteries should be changed as appropriate to allow a reasonable amount of redundancy in
the event of an incident. Battery and fuel management specific to the UAS is contained in the
QRH where necessary.
On battery replacement, the UAS should be given a brief pre-flight check before a new flight
is started.
B2.8: Preparation and assembly of the UAS
The UAS must be carefully assembled and checked using the pre-flight checklist in section F7
of the QRH. If necessary, reference should be made to the UAS manual. The RP will have
been trained in correct assembly and should recheck the UAS between flights.
B2.9: Loading of equipment on the UAS
Equipment to be loaded onto the UAS should be carefully attached in line with the
manufacturer's guidelines and the training received on the different configurations of the UAS.
This will include correct connection of the payload mount to the airframe and flight computer
as well as correct connection of the payload to the mount. Secondary fixings for payloads
should be used where appropriate to ensure that the payload cannot separate from the aircraft.
All equipment should be checked for functionality before the operation commences. The
centre of gravity of the aircraft must be checked before the operation commences.
B3: Flight Procedures
Flight procedures for each UAS used by The SUA Operator are contained in section F8 of the
QRH for that aircraft type in Appendix F.
Version 2.1 Swansea University Operations Manual
DTOM4.6 29/01/2020
B4: Emergency Procedures
Emergency procedures appropriate to each UAS used by The SUA Operator are contained in
section F10 of the QRH for that aircraft type in Appendix F.
B4.1: Fire
The RP must have access to some form of firefighting equipment or an appropriate procedure
if firefighting equipment is not available or not permitted. If the UAS is damaged in a crash the
flight battery, if possible, must be disconnected, removed and placed in an open area away
from flammable objects. The battery should be monitored for swelling and the crew warned to
stay clear. In the event of a fire, the extinguisher/blanket should be used to minimize spread
of flame. If an extinguisher/blanket is not available or not permitted, then the fire services
should be contacted. If possible, the battery should be allowed to burn itself out.
B4.2 Incident management
In the event of an incident the RP should follow the emergency procedures in section F11 of
the aircraft QRH.
Version 2.1 Swansea University Operations Manual
DTOM4.6 29/01/2020
Part C: Additional Operating Procedures
C1: Night operation procedures
C1.1: Overview
When an operation is required outside of daylight hours an additional set of procedures as
outlined in this section will be adhered to. Please note these are in addition to the standard
procedures outlined in this manual. All night operations will be flown by Line of Sight. Before
all night operations, a daylight recce must be carried out.
C1.2: Adequate Ground Lighting
Lighting in the set-up area will be provided by work lamps. All ground equipment (and the UAS
during pre-flight checks) will be kept in the set-up area to ensure that it does not become a
safety hazard or inadvertently damaged.
The primary and the alternative landing zone will be marked out with appropriate lighting where
necessary. The area around the landing zones will be illuminated with work lamps where
ambient lighting is not sufficient.
C1.3: Ground Safety
If the area around the landing zone does not naturally restrict access, a cordon will be erected.
Apart from the RP there will be at least one additional ground crew to ensure that no
unauthorised persons are near the UAS during take-off and landing. Additional Observer/Crew
will be used if deemed necessary following the site assessment.
C1.4: Flight Paths
Given the night conditions, the flight paths will be planned during daylight hours at the site
assessment. The flight paths should be maintained as simple as possible
C1.5: Lighting for night Operations
Any aircraft used for night operations will be illuminated. The standard aircraft illumination may
be sufficient but extra LEDs may be employed to increase visibility to the Remote Pilot.
The illumination is present to assist the RP with orientation and flight rather than to enable
other air users to see the UAS. In the event of an airprox incident it is likely that a pilot would
perceive the UAS as a distant aircraft. As a result, standard operating procedures for spotting
other air users are of utmost importance during night operations.

F4: Likely outcome of failure of propeller or ESC
The 3DR Solo is a quadcopter. As a result there is no redundancy in the event of propeller or
ESC failure and the aircraft is likely to enter uncontrolled vertical descent.
F5: Battery Management
Battery details for the 3DR Solo are as follows:
Item Detail
Battery type Intelligent lithium polymer battery
Number required for
flight
1
Battery capacity 5200mAh
Battery voltage 14.8V
Watt hours 77 Wh
Charger type 3DR smart charger
Charge instructions Sit the charger in a safe location on a non-flammable surface.
Attach batteries to smart charger. Observe batteries initially to
ensure that charge initiates.
Additional instructions The charger should only be set up by a crew member who is
familiar its use and the battery being charged should be
monitored. Lithium-polymer batteries can become unstable.
The two main causes of this are damage during a crash and
improper charging. Any battery that is noticeably swelling
should be placed in a safe place. There have been occasions
when lithium polymer batteries have burst into flame. If a
battery is involved in a crash, it should not be used for the
remainder of the operation until it has been checked by the
Technical Manager even if it appears undamaged and the
UAS is operational.

F10: Emergency Procedures
Pilots should take the time to review this section before flight and to understand the
procedures to implement in different emergency situations.
10.1: Mitigation Measure - 3DR failsafe
This UAS uses the 3DR failsafe return-to-home system. In the event of Tx signal loss it will
carry out the following:
1. hover
2. ascend to user defined height (or remain at current height if already above defined
height)
3. move to a position over the “home” point
4. descend and auto-land
5. switch off motors
The UAS can then be shut-down.
This procedure can also be initiated by holding the return-to-home (RTH) button on the Tx.
10.2: Mitigation Measure – 3DR geofencing
All 3DR systems can be restricted to preset distance limits to reduce the risk of fly-away. It is
recommended that the distance and height limit are set to the minimum distance required to
carry out each project.
10.3: Crew warning
If at any time the craft descends in an uncontrolled measure the RP should shout “HEADS”
to warn crew members. The briefing should include what action any crew should take on
hearing the shout. The response may vary by operation.
10.4: Responses to emergency situations
Loss of primary control frequency including Transmitter battery failure
In the event of loss of control frequency, including Tx failure or Tx battery failure, the aircraft
will enter failsafe as described above. At this point it is the responsibility of the pilot/crew to
maintain the take-off area clear.
Malicious or accidental interference with control frequency
In the event of interference with the control frequency, it is highly likely that the aircraft will
enter failsafe and return to base. If that is not the case then the incident should initially be
treated as a fly-away as described below. Once the aircraft is safely recovered, the cause of
the interference should be investigated and reported appropriately.
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
Loss of power or aircraft battery failure
In the event of power loss to the flight controller or motors, the aircraft may crash, normally
vertically. As a result it is important that the area below the aircraft is maintained clear and
that people in the area are aware of the potential risk. If possible the “HEADS” warning
should be given.
Pilot incapacitated
In the event of the RP becoming incapacitated whilst the UAS is in flight the aircraft will
remain in hover and descend vertically to land under low battery voltage. If crew or observer
are used, instructions can be given on how to initiate RTH in the event of pilot incapacitation.
Aircraft incursion
If another aircraft is seen and appears to be entering or approaching the operating area the
RP should descend the UAS until it is clear there is no risk and may then continue the
operation or land in the take- off area and wait if necessary. If possible “AIRCRAFT” warning
should be given.
Propeller or motor failure
On loss of a propeller or motor it is likely the UAS will enter uncontrolled descent. In this
case the priority is the safety of the public, client and crew so the key mitigation is avoiding
the presence of crew or public immediately below the flight path. If possible the “HEADS”
warning should be given.
Total electronic failure
If this occurs it is likely that the UAS will enter uncontrolled descent. If possible the “HEADS”
warning should be given. If injury occurs it should be ascertained if emergency services are
needed and first aid carried out as necessary. As soon as is appropriate the UAS must be
made safe by disconnecting the flight battery. Once the situation has been dealt with the
incident must be logged and reported appropriately.
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
“Fly-away”
Fly away is heavily mitigated by the distance limiting feature of the DJI flight controller. The
RP should ensure that an appropriate maximum distance and height are programmed for
each operation up to a maximum of 500m horizontally and 400 feet (122m) from the surface.
In the event of a “fly-away” the RP should attempt to regain control:
Attempt atti mode flight
Attempt RTH
Attempt to force failsafe by turning off transmitter
Turn transmitter back on and if appropriate attempt to cut motors (CSC)
If above fails, log the direction, speed, altitude and estimated flight time of the UAS and
immediately contact the Police and local ATC to inform them. If safe to do so the UAS
should be tracked until it lands under second-level low battery protection.
Fire in the air
If control is still possible, attempt to land the aircraft away from crew and on a non-
flammable surface. Follow procedures below.
Fire on the ground
Allow the battery fire to burn out.
Prevent the spread of flame if necessary using the fire extinguisher/blanket. Avoid smoke
inhalation as the smoke is toxic.
If necessary contact fire services.
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
F11: Incident management
In the event of an incident the RP should follow the procedures below. In the event of injury,
the casualty is the priority. If necessary, emergency services should be contacted.
In the event of an incident causing injury or fatality
Stage Item Check
1 Make the UAS safe by removing flight battery if possible
2 Administer first aid as necessary
3 Contact emergency services if necessary
4 Any injured person remains the priority until they are stabilized and if
necessary paramedics have control
5 Take witness statements if appropriate
6 Photograph the scene to show position of the UAS
7 Ensure any footage is retained to show as evidence
8 Repack components and UAS
9 Log the details of the accident and report as necessary
In the event of an incident not causing injury
Stage Item Check
1 Make the UAS safe by removing flight battery if possible
2 Monitor flight battery for swelling and/or fire
3 Take witness statements if appropriate
4 Photograph the scene to show position of the UAS
5 Ensure any footage is retained to show as evidence
6 Log the details of the accident and report as necessary
After any accident or incident the RP should ensure that all appropriate logs are completed
and that, if appropriate, the incident is reported. No further flights should be carried out until
the cause of the incident is established and any risk of re-occurrence is mitigated.

M2: Aircraft-Specific Maintenance details
Maintenance
This section covers basic operational maintenance procedures for Solo. For repairs not
covered in this manual, contact 3DR Support or an authorized Solo Service Center.
Solo’s exterior components are designed to absorb impact from hard landings and protect
the core electronics. If damage is sustained to Solo’s legs or motors, replace them with
official 3DR parts from store.3dr.com or an authorized retailer. 3DR offers an extended
controller battery upgrade with double the capacity so you can fly longer between charges.
Before opening the battery bay or performing any maintenance on Solo, always ensure that
Solo is powered off with the battery removed.
Controller Battery Replacement
To replace the controller battery, open the battery door on the back of the controller.
Remove the foam block and disconnect the battery from the port in the side of the battery
compartment. To install a battery, connect the battery to the controller, and, for standard-size
controller batteries, use the foam block to pad the empty space in the compartment. For
information on safely storing spare controller batteries, see Section 4.10.
Calibrations
Use the Solo app to perform compass and level calibrations when prompted by the
controller. Remove Solo’s propellers before performing calibrations.
Compass Calibration
To calibrate Solo’s compass, connect the app to Solo Wi-Fi, go to Settings > Solo and select
Compass Calibration. Ensure that Solo and the controller are powered on with the propellers
removed. Solo requires an interference-free environment for compass calibration, so ensure
that you are away from metal buildings, reinforced concrete, or other metal structures before
starting calibration.
The app prompts you to rotate Solo end-over-end multiple times until the bar at the top of the
screen is completely green. If the calibration fails, move to a different location and try again.
Level Calibration
A level calibration zeroes Solo’s accelerometers to recognize static states. To perform a
level calibration, remove the propellers from Solo and connect the app to Solo Wi-Fi. Go to
Settings Solo and choose Level Calibration from the list, and follow the prompts to place
Solo perfectly still on each side in turn. In each step, wait a few seconds after moving Solo to
press Next.

DTQRH3.2 29/01/2020
Pairing the Controller
Turn off the Solo and the controller that you want to pair, along with any other Solos and
controllers nearby. Power on the Solo and controller that you want to pair.
Wait 30 seconds for Solo and the controller to fully boot up.
Identify the Pair button underneath Solo. It’s a small button inside the hole labeled Pair.
You’ll need to use a paper clip, a small screwdriver, or another similar tool to push it.
Press the Pair button underneath Solo and hold for one second.
When the controller detects Solo, it prompts you to accept the pairing request as seen in the
screen below. (If the controller does not detect Solo after thirty seconds, try pressing the Pair
button underneath Solo again and repeat as needed.)
Press A, then B and hold both buttons down. Once the controller vibrates, release the
buttons. Within 20 seconds, the Controller displays “Solo Paired.”
Legs
Solo uses three unique types of legs: two legs with an antenna module (#1 and #2), a leg
with no electronic components (leg #3), and a leg with a compass module (leg #4).
Leg #3
To replace a standard leg, use a #2 Phillips screwdriver to remove the two screws, detach
the old leg, and attach the new leg using the provided screws.
Legs #1 and #2 with Antennas
To replace a leg with an antenna module where the existing antenna is physically intact,
you’ll need to remove the antenna from the old leg before replacing it.
To detach the antenna, remove the plastic sheet from the leg (1) and detach the antenna
from the Velcro by carefully pulling the cable (2). Follow the standard leg replacement
procedure to detach the old leg (3).
Attach the new leg by threading the antenna cable through the notch in the top of the leg (1)
and securing the leg using the provide screws (2).
To secure the antenna to the new leg, use the provided Velcro to attach only the yellow-
backed Velcro strip to the Velcro on the antenna. Then remove the backing and attach the
Velcro and antenna to the inside of the leg, placing the tip of the antenna five mm from the
edge of the rubber foot (1) as shown in the following illustration. Fold the ends of a provided
plastic sheet at right angles (2), remove the adhesive backing, and stick the plastic sheet to
the leg so it secures the antenna in place (3).
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
Leg #4 with Compass
Solo’s right-rear leg (#4) contains the compass module. Start by detaching the leg from the
arm as you would a standard leg, but the leg will not be removable until you disconnect the
compass from Solo. To access the compass connector, you’ll need to remove the battery
tray from Solo. For battery tray removal instructions, see Section 10.5.
With the battery tray removed, locate the compass connector in the corner of the board
closest to the leg being replaced. Disconnect the compass connector from the board by
holding down the tab on the far side of the connector and lifting up the connector. Because
the space between the arm and the connector is limited, it might help to use a screwdriver to
press the tab.
With the compass disconnected, remove the old leg and cable from Solo. Place the new leg
into position and thread the new compass cable through the arm where it can connect to the
board. Connect the compass connector in the same place as the old compass.
Secure the new leg in place and replace the battery tray.
Battery Tray
The battery tray holds the battery and GPS in place, and allows you to access the main
electronics bay. This section covers how to remove to tray to access the interior of Solo.
GPS Cover
The GPS cover is the flat, black end cap in front of the battery tray. To remove the GPS
cover, use your fingernails (1) to release the side clips outward. Next, lift slightly while
pushing forward (2) to pop the cover off completely.
: GPS Cover Removal
Battery Tray Removal
To detach the battery tray and access Solo’s main electronics bay, use a small Philips
screwdriver to remove the seven screws securing the battery tray to Solo.
The battery tray is still connected to Solo via the GPS cable, so carefully lift out the tray just
enough to access the board beneath.
Motor Mods
Replacement motors are available as clockwise and counterclockwise Motor Pods. Use a
counterclockwise Motor Pod to replace motors #1 and
#2, and use a clockwise Motor Pod to replace motors #3 and #4. Replace motor pods after
every 150 hours of flight or when they can no longer turn smoothly.
To replace a Motor Pod, first use a small, flat prying tool to remove the LED cover form the
underside of the arm.
Use a #2 Phillips screwdriver to remove the four screws securing the pod to the arm.
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
Disconnect the wide beige connector, the red wire and the black wire to remove the old
motor pod. To remove the wide beige connector (DF13), carefully lift the edges of the
connector away from the pod until they pop out, then remove the connector. Don’t pull on the
wires! The connector can break easily you use force to remove it.
Connect the three cables from the arm to the new motor pod. Tuck the cables inside the arm
and set the new pod into place.
Turn over Solo and secure the new motor pod into place using the four provided screws. Do
not reuse the screws from the old Motor Pod. Finally, snap the LED cover back into place.
Factory Reset
Performing a factory reset restores Solo and the controller to their state prior to the first flight
update. Use a factory reset if you forget your Solo Wi-Fi password or need to restore Solo’s
factory settings.
Contact customer support before performing a Factory Reset. This procedure can cause
irreparable damage to Solo.
Step 1: Reset the Vehicle
As part of the reset procedure, Solo is un-paired from the Controller. Start by powering off
Solo. Use a paper
clip or similar tool to press and hold Solo’s Pair button while powering on Solo. (Make sure
you feel the Pair button click down underneath the paper clip to verify you have properly
activated the Pair button.) Continue holding the Pair button for at least 15 seconds.
Below the Accessory Port and adjacent to the Pair button is a small orange LED Pair
indicator light. Once this light starts flashing rapidly (strobing about five times per second),
release the Pair button.
Step 2: Reset the Controller
Start with the Controller powered off. Hold the Power and Fly buttons simultaneously until
you see the controller-updating display. The Controller then restarts, taking up to five
minutes, and then the screen turns off for one minute.
When the Controller reset is complete, you will see one of these two completion screens:
As the vehicle reset nears completion, the lights under the arms change between many
different colors, followed by a sequence of beeps. When the lights stop changing color, the
reset is complete. Upon completion, the lights freeze on their current colors, so they might all
be the same or different colors.
Step 3: Reboot Solo and the Controller
While rebooting, Solo emits its regular startup tones. The lights underneath Solo’s arms also
light up green and change to white in the front and red in the back. If you do not hear and
see these signals, then reboot Solo again. If the lights change colors now, then the vehicle is
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
still resetting. Let Solo finish resetting and then reboot Solo again once the lights stop
changing colors.
After you reboot the controller, it displays the Preflight Update or Waiting for Solo screen.
Step 4: Pair Solo and the Controller
For instructions on pairing Solo and the Controller, see section 10.3.
Step 5: Update your system
For instructions on updating your system, see section 2.6.4. The Factory Reset procedure is
now complete.

F4: Likely outcome of failure of propeller or ESC
The DJI Inspire 2 is a quadcopter. As a result, there is no redundancy in the event of
propeller or ESC failure and the aircraft is likely to enter uncontrolled vertical descent.
F5: Battery Management
Battery details for the DJI Inspire 2 are as follows:
Item Detail
Battery type Intelligent lithium polymer battery
Number required for
flight
2
Battery capacity TB50: 4280mAh
Battery voltage TB50: 22.8V
Watt hours TB50: 97.58Wh
Charger type DJI smart charger
Charge instructions Sit the charger in a safe location on a non-flammable surface.
Attach batteries to smart charger. Observe batteries initially to
ensure that charge initiates.
Additional instructions Batteries must be periodically discharged to below 5% as
directed within the DJI app. The charger should only be set up
by a crew member who is familiar its use and the battery being
charged should be monitored. Lithium-polymer batteries can
become unstable. The two main causes of this are damage
during a crash and improper charging. Any battery that is
noticeably swelling should be placed in a safe place. There
have been occasions when lithium polymer batteries have
burst into flame. If a battery is involved in a crash, it should not
be used for the remainder of the operation until it has been
checked by the Technical Manager even if it appears
undamaged and the UAS is operational.

F10: Emergency Procedures
RPs should take the time to review this section before flight and to understand the
procedures to implement in different emergency situations.
10.1: Mitigation Measure - DJI failsafe
This UAS uses the DJI failsafe return-to-home system. In the event of Tx signal loss it will
carry out the following:
hover for 3 seconds
ascend to user defined height (or remain at current height if already above defined height)
move to a position over the “home” point
descend at a rate of 0.5 m/s and auto-land
switch off motors after 3 seconds
The UAS can then be shut-down.
This procedure can also be initiated from the APP or by holding the return-to-home (RTH)
button on the Tx.
10.2: Mitigation Measure – DJI geofencing
All DJI systems can be restricted to preset distance limits to reduce the risk of fly-away. It is
recommended that the distance and height limit are set to the minimum distance required to
carry out each project.
10.3: Crew warning
If at any time the craft descends in an uncontrolled measure the RP should shout “HEADS”
to warn crew members. The briefing should include what action any crew should take on
hearing the shout. The response may vary by operation.
10.4: Responses to emergency situations
Loss of primary control frequency including Transmitter battery failure
In the event of loss of control frequency, including Tx failure or Tx battery failure, the
aircraft will enter failsafe as described above. At this point it is the responsibility of the
RP/crew to maintain the take-off area clear.
Malicious or accidental interference with control frequency
In the event of interference with the control frequency, it is highly likely that the aircraft will
enter failsafe and return to base. If that is not the case then the incident should initially be
treated as a fly-away as described below. Once the aircraft is safely recovered, the cause
of the interference should be investigated and reported appropriately.
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
Loss of power or aircraft battery failure
In the event of power loss to the flight controller or motors, the aircraft may crash, normally
vertically. As a result it is important that the area below the aircraft is maintained clear and
that people in the area are aware of the potential risk. If possible the “HEADS” warning
should be given.
Remote Pilot incapacitated
In the event of the RP becoming incapacitated whilst the UAS is in flight the aircraft will
remain in hover and descend vertically to land under low battery voltage. If crew or
observer are used, instructions can be given on how to initiate RTH in the event of RP
incapacitation.
Aircraft incursion
If another aircraft is seen and appears to be entering or approaching the operating area
the RP should descend the UAS until it is clear there is no risk and may then continue the
operation or land in the take-off area and wait if necessary. If possible “AIRCRAFT”
warning should be given.
Propeller or motor failure
On loss of a propeller or motor it is likely the UAS will enter uncontrolled descent. In this
case the priority is the safety of the public, client and crew so the key mitigation is avoiding
the presence of crew or public immediately below the flight path. If possible the “HEADS”
warning should be given.
Total electronic failure
If this occurs it is likely that the UAS will enter uncontrolled descent. If possible the
“HEADS” warning should be given. If injury occurs it should be ascertained if emergency
services are needed and first aid carried out as necessary. As soon as is appropriate the
UAS must be made safe by disconnecting the flight battery. Once the situation has been
dealt with the incident must be logged and reported appropriately.
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
“Fly-away”
Fly away is heavily mitigated by the distance limiting feature of the DJI flight controller.
The RP should ensure that an appropriate maximum distance and height are programmed
for each operation up to a maximum of 500m horizontally and 400 feet (122m) from the
surface.
In the event of a “fly-away” the RP should attempt to regain control:
Attempt atti mode flight
Attempt RTH
Attempt to force failsafe by turning off transmitter
Turn transmitter back on and if appropriate attempt to cut motors (CSC)
If above fails, log the direction, speed, altitude and estimated flight time of the UAS and
immediately contact the Police and local ATC to inform them. If safe to do so the UAS
should be tracked until it lands under second-level low battery protection.
Fire in the air
If control is still possible, attempt to land the aircraft away from crew and on a non-
flammable surface. Follow procedures below.
Fire on the ground
Allow the battery fire to burn out.
Prevent the spread of flame if necessary using the fire extinguisher/blanket. Avoid smoke
inhalation as the smoke is toxic.
If necessary contact fire services.
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
F11: Incident management
In the event of an incident the RP should follow the procedures below. In the event of injury,
the casualty is the priority. If necessary, emergency services should be contacted.
In the event of an incident causing injury or fatality
Stage Item Check
1 Make the UAS safe by removing flight battery if possible
2 Administer first aid as necessary
3 Contact emergency services if necessary
4 Any injured person remains the priority until they are stabilized and
if necessary paramedics have taken control
5 Take witness statements if appropriate
6 Photograph the scene to show position of the UAS
7 Ensure any footage is retained to show as evidence
8 Repack components and UAS
9 Log the details of the accident and report as necessary
In the event of an incident not causing injury or fatality
Stage Item Check
1 Make the UAS safe by removing flight battery if possible
2 Monitor flight battery for swelling and/or fire
3 Take witness statements if appropriate
4 Photograph the scene to show position of the UAS
5 Ensure any footage is retained to show as evidence
6 Log the details of the accident and report as necessary
After any accident or incident, the RP should ensure that all appropriate logs are completed
and that, if appropriate, the incident is reported. No further flights should be carried out until
the cause of the incident is established and any risk of re-occurrence is mitigated.

F9: Emergency Procedures Pilots should take the time to review this section before flight and to understand the procedures to implement in different emergency situations.
9.1: Mitigation Measure - eBee failsafe return to home The eBee has a variety of internal return to home waypoint procedures whereby the eBee returns to the home waypoint and holds position to await further commands when:
a) eBee goes beyond 500m operating radius from home waypoint b) strong winds are detected c) low power detected d) loss of link to tablet for 30s e) Poor GPS/GLONASS coverage f) Camera malfunction detected
Additionally, in the case where ground is detected the eBee will seek to climb unless in a landing sequence. 9.2: Mitigation Measure – eBee land now
In the case of a critical failure where the drone’s ability to fly is compromised (e.g GPS
signal loss or detection of empty battery) the SUA will land immediately based on an in-
built procedure.
9.3 Mitigation measure – in-built emergency commands
There are 5 emergency procedures built into the eMotion software that controls the eBee RTK.
There are additionally 4 other procedures that may be useful in an emergency situation.
The emergency procedures are:
• Land now: the SUA immediately initiates a circular landing around a 30m radius waypoint
at its current location.
• Abort landing: if the landing process looks unsafe after landing has been initiated, the abort
landing command climbs to a defined safe altitude and circles waiting for further commands.
• Roll: the SUA performs a roll along a linear flight path and then resumes its mission. This
command is most useful to protect the drone from attack from bird of prey.
• Fast climb: the SUA climbs suddenly with full thrust approximately 40m and then gradually
descends to initial altitude.
• Fast descent: the SUA enters a spinning dive leading to a loss of 15-30m of altitude before
gradually climbing. This should only be used when the aircraft is flying above 40m.
Additional in-built procedures which may be useful in an emergency are:
• Hold position: the SUA starts to circle about its current position until given further
commands
• Go land: SUA flies to the home waypoint and initiates landing procedure
• Go start waypoint: SUA flies to the start waypoint, circles and waits for further commands
• Go home waypoint: SUA flies to the home waypoint, circles and waits for further commands
Version 2.1 Swansea University Operations Manual
DTHQRH3.2 29/01/2020
For emergencies needing further avoidance, the autopilot can be overridden and manual control of
the SUA activated. A remote control can then be used to control the SUA: assisted manual control
will be used whereby the remote control changes direction, height and speed rather than the
thrust, ailerons and elevator directly. Manual control will only ever be used in the last resort.
9.4: Crew warning
If at any time the craft descends in an uncontrolled measure the RP should shout “HEADS”
to warn crew members. The briefing should include what action any crew should take on
hearing the shout. The response may vary by operation.
9.5: Responses to emergency situations
Loss of primary control frequency including Transmitter battery failure
In the event of loss of control link the eBee will return to the home waypoint. At this point the
manual remote control can be turned on to safely land the eBee
Malicious or accidental interference with control frequency
In the event of interference with the control frequency, it is highly likely that the aircraft will enter
failsafe and return to base. If that is not the case then the incident should initially be treated as a
fly-away as described below. Once the aircraft is safely recovered, the cause of the interference
should be investigated and reported appropriately.
Loss of power or aircraft battery failure
In the event of power loss to the motors, the eBee will attempt to land immediately, the aircraft
may crash. As a result it is important that the area below the aircraft is maintained clear and that
people in the area are aware of the potential risk. If possible the “HEADS” warning should be
given.
Pilot incapacitated
In the event of the RP becoming incapacitated whilst the UAS is in flight the aircraft will remain
in hover and descend vertically to land under low battery voltage. If crew or observer are used,
instructions can be given on how to initiate RTH in the event of pilot incapacitation.
Aircraft incursion
If another aircraft is seen and appears to be entering or approaching the operating area the RP
should turn to manual remote control and descend the UAS until it is clear there is no risk and
may then continue the operation or land in the take-off area and wait if necessary. If possible
“AIRCRAFT” warning should be given.
Propeller or motor failure
On loss of a propeller or motor it is likely the UAS will enter uncontrolled descent. In this case the
priority is the safety of the public, client and crew so the key mitigation is avoiding the presence
of crew or public immediately below the flight path. If possible the “HEADS” warning should be
given.
Total electronic failure
Version 2.1 Swansea University Operations Manual
DTHQRH3.2 29/01/2020
If this occurs it is likely that the UAS will enter uncontrolled descent. If possible the “HEADS”
warning should be given. If injury occurs it should be ascertained if emergency services are
needed and first aid carried out as necessary. As soon as is appropriate the UAS must be made
safe by disconnecting the flight battery. Once the situation has been dealt with the incident must
be logged and reported appropriately.
“Fly-away”
Fly away is heavily mitigated by the distance limiting feature of the emotion2 software. The
RP should ensure that an appropriate maximum distance and height are programmed for
each operation up to a maximum of 500m horizontally and 400 feet (122m) altitude.
In the event of a “fly-away” the RP should attempt to regain control:
1) Attempt to force manual control by turning on remote control and using to land aircraft
2) Attempt to force return to home failsafe by turning off transmitter
3) Turn transmitter back on and if appropriate attempt to cut motors (CSC)
If above fails, log the direction, speed, altitude and estimated flight time of the UAS and
immediately contact the Police and local ATC to inform them. If safe to do so the UAS should be
tracked until it lands under second-level low battery protection.
Fire in the air
If control is still possible, attempt to land the aircraft away from crew and on a non-flammable
surface. Follow procedures below.
Fire on the ground
Allow the battery fire to burn out.
Prevent the spread of flame if necessary using the fire extinguisher/blanket. Avoid smoke
inhalation as the smoke is toxic.
If necessary contact fire services.

DTHQRH3.2 29/01/2020
F4: Likely outcome of failure of propeller or ESC
The Swell Pro SplashDrone3+ is a quadcopter. As a result, there is no redundancy in the event of
propeller or ESC (40A) failure and the aircraft is likely to enter uncontrolled vertical descent.
F5: Battery Management
Battery details for the SplashDrone 3+ are as follows:
Item Detail
Battery type High Voltage Lithium Polymer Battery 4S 15.2V 5200mAh LiHV battery
Number required for
flight
2 (one battery powers the drone, the other powers the remote
controller).
Battery capacity 520mAh
Battery voltage 15.2V
Battery Weights 561g
Charger type SplashDrone 3+ Battery Charger
Charge instructions Always use the SwellPro approved charger. Do not charge battery
immediately after flight because the battery temperature may be too
high. Site the charger in a safe location on a non-flammable surface.
Attach batteries to smart charger. Observe batteries initially to
ensure that charge initiates.
Additional instructions The charger should only be set up by a crew member who is familiar
its use and the battery being charged should be monitored. Batteries
should be stored in LiPo battery cases. Lithium-polymer batteries
can become unstable. The two main causes of this are damage
during a crash and improper charging. Any battery that is noticeably
swelling should be placed in a safe place and if a battery is to be
disposed of check the manual for safe disposal guidelines and inform
the technical manager. There have been occasions when lithium
polymer batteries have burst into flame. If a battery is involved in a
crash, it should not be used for the remainder of the operation until it
has been checked by the Technical Manager even if it appears
undamaged and the UAS is operational.

DTHQRH3.2 29/01/2020
F10: Emergency Procedures
RPs should take the time to review this section before flight and to understand the procedures to
implement in different emergency situations.
There are 3 flight modes on the SwellPro;
1. GPS mode: This mode uses the GPS module to achieve accurate and stabilized hovering, braking, intelligent flight, intelligent return and other intelligent fight mode functions. In this mode, maximum flight speed is 10m/s, maximum ascend speed is 4m/s, and maximum descend speed is 3m/s.
2. Smart Cruise: Specially designed for smooth aerial filming. The turning function of the
left joystick is disabled, and is blended into the right joystick function, to achieve smooth sweeping turns with a single control.
3. ATTI mode: This is a more advanced flight mode which does not use the GPS positioning function but still maintains altitude stabilization. The drone will drift with any wind when hovering and will not brake when the joysticks are released.
10.1: Mitigation Measure –SwellPro Return Home
The SplashDrone 3+ has an Auto return home function if GPS successfully recorded the home point before take-off. If the remote controller and the aircraft loose communication with each other, the drone will automatically return to the take off point and land. The Return Home function can also be manually initiated from the remote controller by using the Return Home switch. A switch must be manually switched on the remote controller to initiate a Return Home function. If the remote controller and the aircraft loose communication with each other, the drone will automatically return to the take-off point and land. During the return process only the right (steering) stick is active. When the drone returns to the home point and commences descent only the left joystick will control direction (heading). At any point the return home function can be cancelled by switching back to normal flight mode.
10.2: Crew warning
Version 2.1 Swansea University Operations Manual
DTHQRH3.2 29/01/2020
If at any time the craft descends in an uncontrolled measure the RP should shout "HEADS" to
warn crew members. The briefing should include what action any crew should take on hearing the
shout. The response may vary by operation.
10.3: Responses to emergency situations
Loss of primary control frequency including Transmitter battery failure
In the event of loss of control frequency, or battery failure, the aircraft will enter return home
mode if GPS is recorded. At this point it is the responsibility of the RP/crew to maintain the take-
off area clear.
Malicious or accidental interference with control frequency
In the event of interference with the control frequency, it is highly likely that the aircraft will enter
return to home mode. If that is not the case then the incident should initially be treated as a fly-
away. Once the aircraft is safely recovered, the cause of the interference should be investigated
and reported appropriately.
Loss of power or aircraft battery failure
In the event of power loss to the flight controller or motors, the aircraft may crash, normally
vertically. As a result it is important that the area below the aircraft is maintained clear and that
people in the area are aware of the potential risk. If possible the "HEADS" warning should be
given. A visual warning light will flash on the screen if the battery voltage is low and in this
scenario the drone will start auto landing in place. Should it be necessary to prevent the auto-
landing, switch the drone into ATTI mode to regain manual control and land the drone.
Remote Pilot incapacitated
In the event of the RP becoming incapacitated whilst the UAS is in flight, if crew or observer are
used, instructions can be given on how to initiate RTH in the event of RP incapacitation i.e.
switch the return home switch on and the drone will land at take-off area.
Aircraft incursion
If another aircraft is seen and appears to be entering or approaching the operating area the RP
should descend the UAS until it is clear there is no risk and may then continue the operation or
land in the take-off area and wait if necessary. If possible "AIRCRAFT" warning should be given.
Propeller or motor failure
On loss of a propeller or motor it is likely the UAS will enter uncontrolled descent. In this case
the priority is the safety of the public, client and crew so the key mitigation is avoiding the
presence of crew or public immediately below the flight path. If possible the "HEADS" warning
should be given.
Total electronic failure
If this occurs it is likely that the UAS will enter uncontrolled descent. If possible the "HEADS"
warning should be given. If injury occurs it should be ascertained if emergency services are
needed and first aid carried out as necessary. As soon as is appropriate the UAS must be made
safe by disconnecting the flight battery. Once the situation has been dealt with the incident must
be logged and reported appropriately.
Version 2.1 Swansea University Operations Manual
DTHQRH3.2 29/01/2020
"Fly-away"
The RP should ensure that an appropriate maximum distance and height are programmed for
each operation up to a maximum of 500m horizontally and 400 feet (122m) altitude.
In the event of a "fly-away" the RP should attempt to regain control:
Attempt ATTI mode flight to gain manual control
Attempt Return to Home function
Turn transmitter back on and if appropriate attempt to cut motors (CSC)
If above fails, log the direction, speed, altitude and estimated flight time of the UAS and
immediately contact the Police and local ATC to inform them. If safe to do so the UAS should be
tracked until it lands under second-level low battery protection.
Fire in the air
If control is still possible, attempt to land the aircraft away from crew and on a non-flammable
surface. Follow procedures below.
Fire on the ground
Allow the battery fire to burn out.
Prevent the spread of flame if necessary using the fire extinguisher/blanket. Avoid smoke

and can still be controlled via its steering surfaces. The ESC powers the servo rail on this aircraft
and as result of an ESC failure the aircraft will thereby go into an uncontrolled descend.

F9: Emergency Procedures Pilots should take the time to review this section before flight and to understand the procedures to implement in different emergency situations. 9.1: Mitigation Measure - DJI failsafe This UAS uses “return-to-home” failsafe system. In the event of Tx signal loss it will carry out the following:
g) Abort mission h) Fly towards “home” while descending to user defined height i) Circle home at predefined height until new user input is registered
The UAS can then either be landed or the mission can be resumed (should UAS status allow). This procedure can also be initiated by flicking the mode switch on the transmitter to RTH. 9.2: Mitigation Measure –geofencing The UAS can be restricted to pre-set distance limits to reduce the risk of fly-away. It is
recommended that the distance and height limit are set to the minimum distance required to carry
out each project.
9.3: Crew warning
If at any time the craft descends in an uncontrolled measure the RP should shout “HEADS”
to warn crew members. The briefing should include what action any crew should take on
hearing the shout. The response may vary by operation.
9.4: Responses to emergency situations
Loss of primary control frequency including Transmitter battery failure
In the event of loss of control frequency, including Tx failure or Tx battery failure, the aircraft will enter
failsafe as described above. At this point it is the responsibility of the pilot/crew to maintain the take-
off area clear.
Malicious or accidental interference with control frequency
In the event of interference with the control frequency, it is highly likely that the aircraft will enter
failsafe and return to base. If that is not the case then the incident should initially be treated as a fly-
away as described below. Once the aircraft is safely recovered, the cause of the interference should
be investigated and reported appropriately.
Loss of power or aircraft battery failure
In the event of power loss to the flight controller or motors, the aircraft may crash, normally vertically.
As a result it is important that the area below the aircraft is maintained clear and that people in the
area are aware of the potential risk. If possible the “HEADS” warning should be given.
Pilot incapacitated
In the event of the RP becoming incapacitated whilst the UAS is in flight the aircraft will remain in
autonomous mode until the mission is finished or low battery voltage is detected. In both cases the
Version 2.1 Swansea University Operations Manual
DTHQRH3.2 29/01/2020
aircraft will at that point go into RTH mode. If crew or observer are used, instructions can be given on
how to initiate RTH in the event of pilot incapacitation.
Aircraft incursion
If another aircraft is seen and appears to be entering or approaching the operating area the RP should
descend the UAS until it is clear there is no risk and may then continue the operation or land in the
take-off area and wait if necessary. If possible “AIRCRAFT” warning should be given.
Propeller or motor failure
On loss of a propeller or motor it is likely the UAS will enter uncontrolled descent. In this case the
priority is the safety of the public, client and crew so the key mitigation is avoiding the presence of crew
or public immediately below the flight path. If possible the “HEADS” warning should be given.
Total electronic failure
If this occurs it is likely that the UAS will enter uncontrolled descent. If possible the “HEADS” warning
should be given. If injury occurs it should be ascertained if emergency services are needed and first
aid carried out as necessary. As soon as is appropriate the UAS must be made safe by disconnecting
the flight battery. Once the situation has been dealt with the incident must be logged and reported
appropriately.
“Fly-away”
Fly away is heavily mitigated by the distance limiting feature of the flight controller. The RP
should ensure that an appropriate maximum distance and height are programmed for each
operation up to a maximum of 500m horizontally and 400 feet (122m) altitude.
In the event of a “fly-away” the RP should attempt to regain control:
4) Attempt RTH
5) Attempt manual mode flight
6) Attempt to force failsafe by turning off transmitter
7) Turn transmitter back on and if appropriate attempt to disarm motors
If above fails, log the direction, speed, altitude and estimated flight time of the UAS and immediately
contact the Police and local ATC to inform them. If safe to do so the UAS should be tracked until it
lands under second-level low battery protection.
Fire in the air
If control is still possible, attempt to land the aircraft away from crew and on a non-flammable surface.
Follow procedures below.
Fire on the ground
Allow the battery fire to burn out.
Prevent the spread of flame if necessary using the fire extinguisher/blanket. Avoid smoke inhalation
as the smoke is toxic.
If necessary contact fire services.

F10: Emergency Procedures
RPs should take the time to review this section before flight and to understand the
procedures to implement in different emergency situations.
10.1: Mitigation Measure - DJI failsafe
This UAS uses the DJI failsafe return-to-home system. In the event of Tx signal loss it will
carry out the following:
1. hover for 3 seconds
2. ascend to user defined height (or remain at current height if already above defined
height)
3. move to a position over the “home” point
4. descend at a rate of 0.5 m/s and auto-land
5. switch off motors
The UAS can then be shut-down.
This procedure can also be initiated from the app or by holding the return-to-home (RTH)
button on the Tx.
10.2: Mitigation Measure – DJI geofencing
All DJI systems can be restricted to preset distance limits to reduce the risk of fly-away. It is
recommended that the distance and height limit are set to the minimum distance required to
carry out each project.
10.3: Crew warning
If at any time the craft descends in an uncontrolled measure the RP should shout “HEADS”
to warn crew members. The briefing should include what action any crew should take on
hearing the shout. The response may vary by operation.
10.4: Responses to emergency situations
Loss of primary control frequency including Transmitter battery failure
In the event of loss of control frequency, including Tx failure or Tx battery failure, the
aircraft will enter failsafe as described above. At this point it is the responsibility of the
RP/crew to maintain the take-off area clear.
Malicious or accidental interference with control frequency
In the event of interference with the control frequency, it is highly likely that the aircraft will
enter failsafe and return to base. If that is not the case then the incident should initially be
treated as a fly-away as described below. Once the aircraft is safely recovered, the cause
of the interference should be investigated and reported appropriately.
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
Loss of power or aircraft battery failure
In the event of power loss to the flight controller or motors, the aircraft may crash, normally
vertically. As a result it is important that the area below the aircraft is maintained clear and
that people in the area are aware of the potential risk. If possible the “HEADS” warning
should be given.
Remote Pilot incapacitated
In the event of the RP becoming incapacitated whilst the UAS is in flight the aircraft will
remain in hover and descend vertically to land under low battery voltage. If crew or
observer are used, instructions can be given on how to initiate RTH in the event of RP
incapacitation.
Aircraft incursion
If another aircraft is seen and appears to be entering or approaching the operating area
the RP should descend the UAS until it is clear there is no risk and may then continue the
operation or land in the take-off area and wait if necessary. If possible “AIRCRAFT”
warning should be given.
Propeller or motor failure
On loss of a propeller or motor it is likely the UAS will enter uncontrolled descent. In this
case the priority is the safety of the public, client and crew so the key mitigation is avoiding
the presence of crew or public immediately below the flight path. If possible the “HEADS”
warning should be given. In the event of ESC failure, power will reroute via the flight
controller and should allow a controlled landing.
Total electronic failure
If this occurs it is likely that the UAS will enter uncontrolled descent. If possible the
“HEADS” warning should be given. If injury occurs it should be ascertained if emergency
services are needed and first aid carried out as necessary. As soon as is appropriate the
UAS must be made safe by disconnecting the flight battery. Once the situation has been
dealt with the incident must be logged and reported appropriately.
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
“Fly-away”
Fly away is heavily mitigated by the distance limiting feature of the DJI flight controller.
The RP should ensure that an appropriate maximum distance and height are programmed
for each operation up to a maximum of 500m horizontally and 400 feet (122m) from the
surface.
In the event of a “fly-away” the RP should attempt to regain control:
Attempt atti mode flight
Attempt RTH
Attempt to force failsafe by turning off transmitter
Turn transmitter back on and if appropriate attempt to cut motors (CSC)
If above fails, log the direction, speed, altitude and estimated flight time of the UAS and
immediately contact the Police and local ATC to inform them. If safe to do so the UAS
should be tracked until it lands under second-level low battery protection.
Fire in the air
If control is still possible, attempt to land the aircraft away from crew and on a non-
flammable surface. Follow procedures below.
Fire on the ground
Allow the battery fire to burn out.
Prevent the spread of flame if necessary using the fire extinguisher/blanket. Avoid smoke
inhalation as the smoke is toxic.
If necessary contact fire services.

DTQRH3.2 29/01/2020
F11: Incident management
In the event of an incident the RP should follow the procedures below. In the event of injury,
the casualty is the priority. If necessary, emergency services should be contacted.
In the event of an incident causing injury or fatality
Stage Item Check
1 Make the UAS safe by removing flight battery if possible
2 Administer first aid as necessary
3 Contact emergency services if necessary
4 Any injured person remains the priority until they are stabilized and
if necessary paramedics have taken control
5 Take witness statements if appropriate
6 Photograph the scene to show position of the UAS
7 Ensure any footage is retained to show as evidence
8 Repack components and UAS
9 Log the details of the accident and report as necessary
After any accident or incident the RP should ensure that all appropriate logs are completed
and that, if appropriate, the incident is reported. No further flights should be carried out until
the cause of the incident is established and any risk of re-occurrence is mitigated.
A mandatory occurrence report can now be raised online via the ECCAIRS system at:

1
Battery capacity 5350mAh
Battery voltage 15.2V
Watt hours 81.3 Wh
Charger type DJI smart charger
Charge instructions Sit the charger in a safe location on a non-flammable surface.
Attach batteries to smart charger. Observe batteries initially to
ensure that charge initiates.
Additional instructions Batteries must be periodically discharged to below 5% as
directed within the DJI app. The charger should only be set up
by a crew member who is familiar its use and the battery being
charged should be monitored. Lithium-polymer batteries can
become unstable. The two main causes of this are damage
during a crash and improper charging. Any battery that is
noticeably swelling should be placed in a safe place. There
have been occasions when lithium polymer batteries have
burst into flame. If a battery is involved in a crash it should not
be used for the remainder of the operation until it has been
checked by the Technical Manager even if it appears
undamaged and the UAS is operational.

F10: Emergency Procedures
Remote Pilots should take the time to review this section before flight and to understand the
procedures to implement in different emergency situations.
10.1: Mitigation Measure - DJI failsafe
This UAS uses the DJI failsafe return-to-home system. In the event of Tx signal loss it will
carry out the following:
1. hover for 3 seconds
2. ascend to user defined height (or remain at current height if already above defined
height)
3. move to a position over the “home” point
4. descend at a rate of 0.5 m/s and auto-land
5. Switch off motors after 3 seconds
The UAS can then be shut-down.
This procedure can also be initiated from the app or by holding the return-to-home (RTH)
button on the Tx.
10.2: Mitigation Measure – DJI geofencing
All DJI systems can be restricted to preset distance limits to reduce the risk of fly-away. It is
recommended that the distance and height limit are set to the minimum distance required to
carry out each project.
10.3: Crew warning
If at any time the craft descends in an uncontrolled measure the RP should shout “HEADS”
to warn crew members. The briefing should include what action any crew should take on
hearing the shout. The response may vary by operation.
10.4: Responses to emergency situations
Loss of primary control frequency including Transmitter battery failure
In the event of loss of control frequency, including Tx failure or Tx battery failure, the
aircraft will enter failsafe as described above. At this point it is the responsibility of the
RP/crew to maintain the take-off area clear.
Malicious or accidental interference with control frequency
In the event of interference with the control frequency, it is highly likely that the aircraft will
enter failsafe and return to base. If that is not the case then the incident should initially be
treated as a fly-away as described below. Once the aircraft is safely recovered, the cause
of the interference should be investigated and reported appropriately.
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
Loss of power or aircraft battery failure
In the event of power loss to the flight controller or motors, the aircraft may crash, normally
vertically. As a result, it is important that the area below the aircraft is maintained clear
and that people in the area are aware of the potential risk. If possible the “HEADS”
warning should be given.
Remote Pilot incapacitated
In the event of the RP becoming incapacitated whilst the UAS is in flight the aircraft will
remain in hover and descend vertically to land under low battery voltage. If crew or
observer are used, instructions can be given on how to initiate RTH in the event of RP
incapacitation.
Aircraft incursion
If another aircraft is seen and appears to be entering or approaching the operating area
the RP should descend the UAS until it is clear there is no risk and may then continue the
operation or land in the take-off area and wait if necessary. If possible “AIRCRAFT”
warning should be given.
Propeller or motor failure
On loss of a propeller or motor it is likely the UAS will enter uncontrolled descent. In this
case the priority is the safety of the public, client and crew so the key mitigation is avoiding
the presence of crew or public immediately below the flight path. If possible the “HEADS”
warning should be given.
Total electronic failure
If this occurs it is likely that the UAS will enter uncontrolled descent. If possible the
“HEADS” warning should be given. If injury occurs it should be ascertained if emergency
services are needed and first aid carried out as necessary. As soon as is appropriate the
UAS must be made safe by disconnecting the flight battery. Once the situation has been
dealt with the incident must be logged and reported appropriately.
Version 2.1 Swansea University Operations Manual
DTQRH3.2 29/01/2020
“Fly-away”
Fly away is heavily mitigated by the distance limiting feature of the DJI flight controller.
The RP should ensure that an appropriate maximum distance and height are programmed
for each operation up to a maximum of 500m horizontally and 400 feet (122m) from the
surface.
In the event of a “fly-away” the RP should attempt to regain control:
Attempt atti mode flight
Attempt RTH
Attempt to force failsafe by turning off transmitter
Turn transmitter back on and if appropriate attempt to cut motors (CSC)
If above fails, log the direction, speed, altitude and estimated flight time of the UAS and
immediately contact the Police and local ATC to inform them. If safe to do so the UAS
should be tracked until it lands under second-level low battery protection.
Fire in the air
If control is still possible, attempt to land the aircraft away from crew and on a non-
flammable surface. Follow procedures below.
Fire on the ground
Allow the battery fire to burn out.
Prevent the spread of flame if necessary using the fire extinguisher/blanket. Avoid smoke
inhalation as the smoke is toxic.
If necessary contact fire services.

F3: Operational envelope
Parameter Limitations
Maximum wind speed 12m/s – 26.8mph – 23.3kt
Maximum service altitude 16,404 feet AMSL (5000m)
Aircraft speed range 11-25m/s – 25-56mph – 21-49kt
Temperature range 10oC to +35oC
Maximum take-off mass (MTOM) 0.7Kg
Flight time 50 minutes (camera & weather dependent)
F4: Likely outcome of failure of propeller or ESC The eBee is a fixed wing plane and has a long glide slope. If there is propeller failure then the
aircraft will self-stabilise to a safe landing. If the ESC fails the elevons are powered from the flight
controller so the aircraft should self-stabilise to a safe landing.

F5: Battery Management Battery details for the eBee are as follows:
Item Detail
Battery type Lithium polymer battery
Number required for flight 1
Battery capacity Between 2150 and 4900 mAh
Battery voltage 11.1V (3S)
Charger type Sensefly LiPo Charger/Discharger
Charge instructions
Sit the charger in a safe location on a non-flammable surface.
Attach batteries to the charger and follow charger’s manual to start
charging. Observe batteries initially to ensure that charge initiates.
Additional instructions
The charger should only be set up by a crew member who is
familiar its use and the battery being charged should be monitored.
Lithium-polymer batteries can become unstable. The two main
causes of this instability are damage during a crash and improper
charging. Any battery that is noticeably swelling should be placed in
a safe place such as a flame proof lipo bag. There have been
occasions when lithium polymer batteries have burst into flame. If a
battery is involved in a crash, it should not be used for the
remainder of the operation until it has been checked by the
Technical Manager, even if it appears undamaged and the UAS is
operational.

F10: Emergency Procedures RPs should take the time to review this section before flight and to understand the procedures to implement in different emergency situations.
10.1: Mitigation Measure - failsafe This aircraft has a failsafe system; in the event of Tx signal loss the aircraft will enter a loiter mode over the home point and on low battery will descend to a safe landing at the pre-programmed location. The UAS can then be recovered and the battery immediately unplugged. 10.2: Crew warning
If at any time the craft descends in an uncontrolled measure the RP should shout “HEADS”
to warn crew members. The briefing should include what action any crew should take on
hearing the shout. The response may vary by operation.
10.3: Responses to emergency situations
Loss of primary control frequency including Transmitter battery failure
In the event of loss of control frequency, including Tx failure or Tx battery failure, the aircraft will
enter failsafe as described above. At this point it is the responsibility of the RP/crew to attempt
recovery of connection to the UAS by power cycling the Tx/laptop.
Malicious or accidental interference with control frequency
In the event of interference with the control frequency, it is highly likely that the aircraft will enter
failsafe. If that is not the case then the incident should initially be treated as a fly-away as
described below. Once the aircraft is safely recovered, the cause of the interference should be
investigated and reported appropriately.
Loss of power or aircraft battery failure
In the event of power loss to the ESC or motor, the aircraft may crash. As a result it is important
that the area within the glide slope is maintained clear and that people in the area are aware of
the potential risk as far as possible. If possible the “HEADS” warning should be given. If enough
power remains, the eBee will attempt to fly to the homepoint and commence an expedited
landing procedure that may be less accurate than normal.
RP incapacitated
In the event of the RP becoming incapacitated whilst the UAS is in flight the aircraft will continue
its mission and loiter after the last waypoint. Crew should be briefed in how to initiate landing. In
the event the RP is operating alone, the aircraft will land on low battery.
Version 2.1 Swansea University Operations Manual
DTHQRH3.2 29/01/2020
Aircraft incursion
If another aircraft is seen and appears to be entering or approaching the operating area the RP
should loiter until it is clear there is no risk and may then continue the operation or land in the
take-off area and wait if necessary. If possible “AIRCRAFT” warning should be given. The rapid
descent button could be used to avoid a collision in the air.
Propeller or motor failure
If loss of a propeller or motor occurs, it is likely the UAS will glide to a landing
Total electronic failure
If total electronic failure occurs it is likely that the UAS will enter uncontrolled descent. If possible
the “HEADS” warning should be given. If injury occurs it should be ascertained if emergency
services are needed and first aid carried out as necessary. As soon as is appropriate the UAS
must be made safe by disconnecting the flight battery. Once the situation has been dealt with the
incident must be logged and reported appropriately.
“Fly-away”
The RP should ensure that an appropriate maximum distance and height are observed for
each operation up to a maximum of 500m horizontally and 400 feet (122m) altitude.
In the event of a “fly-away” the RP should attempt to regain control by restarting the eMotion
software then try power cycling the transmitter and/or laptop and if appropriate attempt to cut
motors.
If above fails, log the direction, speed, altitude and estimated flight time of the UAS and
immediately contact the Police and local ATC to inform them. If safe to do so the UAS should be
tracked until it lands.
Fire in the air
If control is still possible, use eMotion to attempt to land the aircraft away from crew and on a
non-flammable surface. Follow procedures below.

F9: Emergency Procedures
Pilots should take the time to review this section before flight and to understand the procedures to
implement in different emergency situations.
9.1 : Mitigation Measure – Autel Robotics failsafe
This UAS uses the Autel Robotics failsafe return-to-home system. In the event of Tx signal loss it will
carry out the following:
a) hover for 3 seconds b) ascend to user defined height (or remain at current height if already above defined height) c) move to a position over the “home” point d) descend at a rate of 0.5 m/s and auto-land
e) Switch off motors after 3 seconds
The UAS can then be shut-down.
This procedure can also be initiated from the APP or by holding the return-to-home (RTH) button on
the Tx.
9.2 : Mitigation Measure – Autel Robotics geofencing
All Autel Robotics systems can be restricted to preset distance limits to reduce the risk of fly-away. It
is recommended that the distance and height limit are set to the minimum distance required to carry
out each project.
9.3 : Crew warning
If at any time the craft descends in an uncontrolled measure the RP should shout “HEADS” to
warn crew members. The briefing should include what action any crew should take on hearing
the shout. The response may vary by operation.
9.4 : Responses to emergency situations
Loss of primary control frequency including Transmitter battery failure
In the event of loss of control frequency, including Tx failure or Tx battery failure, the aircraft will
enter failsafe as described above. At this point it is the responsibility of the pilot/crew to maintain the
take-off area clear.
Malicious or accidental interference with control frequency
In the event of interference with the control frequency, it is highly likely that the aircraft will enter
failsafe and return to base. If that is not the case then the incident should initially be treated as a fly-
away as described below. Once the aircraft is safely recovered, the cause of the interference should
be investigated and reported appropriately.
Loss of power or aircraft battery failure
In the event of power loss to the flight controller or motors, the aircraft may crash, normally vertically.
As a result it is important that the area below the aircraft is maintained clear and that people in the
area are aware of the potential risk. If possible the “HEADS” warning should be given.
Version 2.1 Swansea University Operations Manual
DTHQRH3.2 29/01/2020
Pilot incapacitated
In the event of the RP becoming incapacitated whilst the UAS is in flight the aircraft will remain in
hover and descend vertically to land under low battery voltage. If crew or observer are used,
instructions can be given on how to initiate RTH in the event of pilot incapacitation.
Aircraft incursion
If another aircraft is seen and appears to be entering or approaching the operating area the RP should
descend the UAS until it is clear there is no risk and may then continue the operation or land in the
take-off area and wait if necessary. If possible “AIRCRAFT” warning should be given.
Propeller or motor failure
On loss of a propeller or motor it is likely the UAS will enter uncontrolled descent. In this case the
priority is the safety of the public, client and crew so the key mitigation is avoiding the presence of
crew or public immediately below the flight path. If possible the “HEADS” warning should be given.
Total electronic failure
If this occurs it is likely that the UAS will enter uncontrolled descent. If possible the “HEADS” warning
should be given. If injury occurs it should be ascertained if emergency services are needed and first
aid carried out as necessary. As soon as is appropriate the UAS must be made safe by disconnecting
the flight battery. Once the situation has been dealt with the incident must be logged and reported
appropriately.
“Fly-away”
Fly away is heavily mitigated by the distance limiting feature of the Autel Robotics flight
controller. The RP should ensure that an appropriate maximum distance and height are
programmed for each operation up to a maximum of 500m horizontally and 400 feet (122m)
altitude.
In the event of a “fly-away” the RP should attempt to regain control:
1) Attempt atti mode flight
2) Attempt RTH
3) Attempt to force failsafe by turning off transmitter
4) Turn transmitter back on and if appropriate attempt to cut motors (CSC) If above fails, log the direction, speed, altitude and estimated flight time of the UAS and immediately
contact the Police and local ATC to inform them. If safe to do so the UAS should be tracked until it
lands under second-level low battery protection.
Fire in the air
If control is still possible, attempt to land the aircraft away from crew and on a non-flammable surface.
Follow procedures below.
Fire on the ground
Version 2.1 Swansea University Operations Manual
DTHQRH3.2 29/01/2020
Allow the battery fire to burn out.
Prevent the spread of flame if necessary using the fire extinguisher/blanket. Avoid smoke inhalation
as the smoke is toxic.
If necessary contact fire services.

F10: Incident management
In the event of an incident the RP should follow the procedures below.
In the event of injury, the casualty is the priority. If necessary, emergency services should be
contacted.
In the event of an incident causing injury or fatality
Stage Item Check
1 Make the UAS safe by removing flight battery if possible
2 Administer first aid as necessary
3 Contact emergency services if necessary
4 Any injured person remains the priority until they are stabilized and if necessary paramedics have taken control
5 Take witness statements if appropriate
6 Photograph the scene to show position of the UAS
7 Ensure any footage is retained to show as evidence
8 Repack components and UAS
9 Log the details of the accident and report as necessary
In the event of an incident causing damage
Stage Item Check
1 Make the UAS safe by removing flight battery if possible
2 Monitor flight battery for swelling and/or fire
3 Take witness statements if appropriate
4 Photograph the scene to show position of the UAS
5 Ensure any footage is retained to show as evidence
6 Log the details of the accident and report as necessary
After any accident or incident the RP should ensure that all appropriate logs are completed and that, if
appropriate, the incident is reported. No further flights should be carried out until the cause of the
incident is established and any risk of re-occurrence is mitigated.

1. Introduction This document provides a basic technical description and operational procedure for the remote
controlled model aircraft that are designed, built and test flown as part of the EGA302a module on
the aerospace engineering course. These aircraft are basic representations of the full scale
conceptual designs that are developed during the module, which can follow various design briefs
ranging from hypersonic transports to unmanned medical supply delivery systems, with students
free to pick any heavier-than-air configuration that can meet the requirements. Therefore, the aircraft
show considerable variety in size and shape.
Swansea University has operating procedures for Unmanned Aerial Systems (UAS) which require
that Quick Reference Handbooks, specifying technical data and operating instructions, are on record
for all types of UAS that are flown. It is unfeasible to produce separate documentation of this nature
for each individual aircraft flown due to the timescales of the assessment. Instead this document
takes the pragmatic approach of defining a broad class of model aircraft referred to as an ‘EGA302a
Design Build Model’ (EDBM), and presenting what technical data and instructional data can be
applied to all such aircraft in a generic QRH. Clearly, such technical data will be relatively vague,
because of the diversity of aircraft that can be produced under this activity. However, by establishing
the envelope of technical data, and the typical operation, for all such aircraft, it will fulfil the purpose
of allowing an audit of documents to see that operating procedures involving these aircraft are fit for
the purpose of ensuring safe operations.
In Section 2, relevant technical data that is available for all such aircraft is presented. In Section 3
an outline operating instructions are provided.

2. Technical data
2.1 Physical data Mass of model (kg) Maximum 5 kg
Typically <3 kg
A survey of 2019 designs
showed a maximum mass of
2.5kg and an average of
1.3kg.
Wingspan (m) Maximum 3 m
Typically <2 m
Minimum flight speed (stall
speed)
< 15m/s Survey of2019 designs,
considering takeoff mass and
wing area and assuming
maximum Cl of 1.5 predicts
average 9.2m/s.
Max flight speed: Estimated to be < 25 m/s
Takeoff method In most cases a throw launch is used although runway take
off is also used.
Landing method Generally a belly landing is used, although some aircraft
have undercarriages.
Due to the relatively untested nature of aircraft, a high
proportion of crash landings are inevitable.
2.2 Propulsion In the vast majority of cases the power system consists of the following items:
• Ripmax Quantum II 480 Brushless Motor
• Ripmax Quantum 60A SBEC Brushless Esc
• Hi-Energy Extreme 3S 1300mAh 30C Li-Po battery
The propeller used is selected on a case by case basis but is in the range 8-10” diameter.
Occasional variations to this are considered, but have similar amounts of power and thrust.
2.3 Control The aircraft are controlled through an FRSky X9D transmitter. The receivers used are nearly always
the FrSky V8R4-II 2.4Ghz 4 Channel Receiver, although when more channels are required FrSky
V8R7-II 2.4Ghz 7 Channel Receiver is used. In exceptional circumstances similar alternatives to
these control systems are substituted.
No telemetry or autonomous on board flight control is used.

DTHQRH3.2 29/01/2020
3. Operating instructions The aircraft are only to be operated by a competent Remote Pilot (RP), who is on Swansea
University’s list of approved UAS operators and have a certificate of competence. Detailed operating
instructions are not feasible due to the variety of aircraft, however the RP will follow the advice given
by the British Model Flying Association (BMFA) for operating newly built model aircraft, as taught
through their pilot accreditation schemes that are recognised by the Civil Aviation Authority (CAA).
A full description of these procedures is beyond the scope of this document but in outline they
ensure:
• Structural robustness of the aircraft, checked prior to flight
• Operation of all flight control surfaces, checked prior to flight
• Failsafe procedures in the case of loss of radio contact
• Safe flight planning and conduct of the flight.
