Screen Layout (windows)

The GNS 530’s display is divided into four separate “windows” (or screen areas).The left 1/4 of the display provides a COM window (top two lines) and a VLOCwindow (by default with VOR ident/radial, but selectable for other data). The right 3/4of the display consists of a GPS window, which is where you’ll find the variousnavigation, waypoint information and settings “pages”. The bottom of the display isused for annunciators.

Each unique screen of information is referred to as a “page”. Pages are typicallyselected using the small and large right knobs—with the cursor removed fromthe GPS window. See page 5 for arrangement of the GNS 530’s main pages.

CursorsThere are two separate cursors: a tuning cursor and a GPS window cursor. The

tuning cursor is used to select the standby COM or VLOC frequency. Pushing thesmall left knob moves the tuning cursor back-and-forth between the COM andVLOC frequency windows. To select the active frequency, you must first enter thefrequency in the standby field, then use the COM or VLOC flip-flop key toactivate the frequency. Use the large right knob to move the GPS window cursoraround the page.

Selecting Approaches

In order to select an approach, you must firsthave an active direct-to or flight plan whichterminates at an airport with a published approach.

1. Press the PROC key to display theProcedures Page.

2. Rotate the large right knob tohighlight “Select Approach?” and pressENT.

3. A window will appear listing the availableprocedures. Rotate the large right knobto highlight the desired procedure andpress ENT.

4. A second window will appear listing theavailable transitions. Rotate the largeright knob to highlight the desiredtransition waypoint and press ENT. (Theapproach “Vectors” option assumes youwill receive vectors to the final coursesegment of the approach and will providenavigation guidance relative to the final approach course.)

5. Rotate the large right knob to highlight “Load?” or “Activate?” andpress ENT. (“Load?” will add the procedure to the flight plan withoutimmediately using it for navigation guidance. This allows you to continuenavigating the original flight plan, but keeps the procedure available on theActive Flight Plan Page for quick activation when needed. “Activate?”overrides the “enroute” portion of the active flight plan, proceeding directlyto the “approach” portion.)

6. For precision approaches and some non-precision approaches, a reminder windowwill appear indicating that GPS guidanceon such approaches is strictly for monitor-ing only—use the VLOC receiver andexternal CDI (or HSI) for primary naviga-tion. To confirm this reminder, highlight“Yes?” and press ENT.

Not all approaches in the database are approved for GPS use. As you select anapproach, a “GPS” designation to the right of the procedure name indicates theprocedure can be flown using the GPS receiver. Some procedures will not have thisdesignation, meaning the GPS receiver may be used for supplemental navigationguidance only. If the GPS receiver cannot be used for primary guidance, you mustuse the appropriate receiver for the selected approach (e.g., VOR or NDB). The finalcourse segment of ILS approaches, for example, must be flown by tuning the VLOCreceiver to the proper frequency and coupling the VLOC receiver to the external CDI(or HSI).

A selected approach may be activated or loaded. Loading the approach adds theprocedure to the flight plan without immediately using it for navigation guidance. Youcan continue navigating the original flight plan, but the procedure is available forquick activation when needed. Activating the approach overrides the “enroute” portionof the active flight plan, proceeding directly to the “approach” portion. Activating theapproach also initiates automatic CDI scaling transition as the approach progresses.

In many cases, it may be easiest to “Load” the full approach while still somedistance away, enroute to the destination airport. Later, if vectored to final, use thefollowing steps to select “Activate Vector-To-Final”—which makes the inbound courseto the FAF waypoint active. Otherwise, activate the full approach using the “ActivateApproach?” option.

14

Activating an Approach1. With an approach loaded in the active

flight plan, press the PROC key to displaythe Procedures Page.

2. Rotate the large right knob tohighlight “Activate Approach?”.

3. Press ENT.

Activating an Approach with Vectors-to-FinalThe “Activate Vectors-To-Final?” option allows you to activate the final course

segment of the approach. This option assumes you will receive vectors to the finalapproach fix (FAF) and guides you to intercept the final course, before reaching theFAF.

1. With an approach loaded in the activeflight plan, press the PROC key to displaythe Procedures Page.

2. Rotate the large right knob tohighlight “Activate Vectors-To-Final?”.

3. Press ENT.

Due to the variety of available approach procedures, the specific steps required willvary according to the approach selected. Keep the following guidelines in mind whileflying the approach:

• The GNS 530 is designed to complement your printed approach plates andvastly improve situational awareness throughout the approach. However, youmust always fly an approach as it appears on the approach plate

• You will typically select the destination airport as the last waypoint in the activeflight plan or using the direct-to key. Doing so ensures that the desiredwaypoint will automatically appear when choosing the “Select Approach?”option for the Procedures Page. (Otherwise, you must first choose the airport,then the approach procedure.)

• When a localizer-based approach (such as an ILS) is loaded, the desiredfrequency is automatically placed in standby on the VLOC window. To activatethe frequency, press the VLOC flip-flop key.

• If the VLOC receiver will be used for the approach, be sure to switch theexternal CDI (or HSI) to “VLOC” by pressing the CDI key. (VLOC will appeardirectly above the CDI key; see page 10.)

• An “ILS CDI Capture” setting provides automatic switching to “VLOC” as youintercept the final approach course. When the ILS approach is activated (and thecorrect frequency is active in the VLOC window), the GNS 530 will automati-cally switch within 1.2 nautical miles left or right of the approach course. Thisswitch can take place anywhere from 2.0 to 15.0 nautical miles from the FAF.The switch occurs gradually to prevent abrupt CDI changes.

• As you progress to each waypoint, a waypoint alert message (e.g.,“NEXTDTK ###°”) will appear in the lower right corner of the display. (See page 10.)

• When you should begin a course change (via a standard rate turn), turnadvisories (“TURN TO ###°”) will appear in the lower right corner of the display.(See page 10.)

15

• For GPS-based approaches, receiver autonomous integrity monitoring (RAIM)will monitor satellite conditions and alert you—using an “INTEG” or “WARN”annunciation at the bottom left corner of the display (see page 10)—ifprotection limits cannot be maintained. If this occurs, the GPS receiver shouldnot be used for primary navigation guidance. Revert to an alternate navigationsource, such as the GNS 530’s VOR/Localizer receiver, or select an alternatedestination airport.

• Within 30 nautical miles of the destination airport, CDI scaling will transitionfrom 5.0 nautical miles (enroute mode; or “ENR”) to 1.0 nautical mile (terminalmode; or “TERM”)—or when leaving the departure airport, from 1.0 nm to5.0 nm. Within 2.0 nautical miles of the final approach fix, GPS-based ap-proaches will see a second transition from 1.0 nautical mile to 0.3 nautical mile(approach mode; or “APR”).

• A “START PROC TURN” prompt will appear in the lower right corner of thedisplay to remind you to initiate a procedure turn (if you haven’t already begunthe procedure turn). The procedure turn is displayed on the Default NAV andMap pages, but guidance through the turn itself is not provided.

• Alerts for proper holding pattern entry (e.g., “HOLD DIRECT”) are displayed inthe lower right corner of the display. Waypoint sequencing is automaticallysuspended (indicated by “SUSP” directly above the OBS key) at the holdingwaypoint. Press the OBS key again to return to automatic waypointsequencing. For course reversals, waypoint sequencing is suspended for onetrip around the holding pattern only (after which it will return to automaticwaypoint sequencing).

• The CDI will guide you through a DME arc. Just keep the needle centered asyou fly along the arc. When using an autopilot, the course select on the CDI (orHSI) must be periodically updated with the desired track (DTK).

• As you cross the missed approach point(MAP), “SUSP” will appear above the OBSkey, indicating that automatic sequencing ofwaypoint is suspended at the missed approachpoint, and a FROM indication will appear onthe CDI (or HSI).

Flying the Missed Approach1. After crossing the missed approach point, press the OBS key. The next

waypoint in the approach is automatically offered as the destinationwaypoint.

2. Follow the missed approach procedures, as published on your approachplate, for proper climb and heading instructions.

3. An alert message in the lower right handcorner of the screen will recommend entryprocedures for a holding pattern (i.e.,“HOLD DIRECT”, “HOLD PARALLEL”, or“HOLD TEARDROP”). As you fly theholding pattern, a timer appears on theDefault NAV Page. The timer automaticallyresets on the outbound side of the hold when you are abeam the holdwaypoint. The timer again resets as you turn inbound (within approximately30° of the inbound course). This allows you to use standard timing (typicallyone minute) to fly the inbound and outbound legs of the hold.

4. The GNS 530 will provide course guidance only on the inbound side of theholding pattern. When leaving the holding pattern to re-fly the approach (oranother approach) press the PROC key to “Select Approach?” or “ActivateApproach?” as previously described. (Or, use the direct-to key to selectanother destination.)
