Because a go-around is not a frequent occurrence, the importance of being go-around-prepared and go-around-minded must be emphasized.

To be go-around-prepared and go-around-minded the flight crew should:• Have a clear mental image of applicable briefings, sequences of actions, task sharing,

standard calls and excessive -deviation callouts;• Be ready to abandon the approach if:

Ceiling and/or visibility (RVR) are below the required minimums; Criteria for a stabilized approach are not achieved; Doubt exists about the aircraft position; and/or, Confusion exists about the use of automation.

If the conditions for a safe approach and landing are not met, the flight crew should be go-around-committed without any hesitation.

PF / PNF Task Sharing

• Strict adherence to task-sharing is main princible.• The PF is responsible for controlling the vertical flight path and lateral flight

path and for energy management.• The PNF is responsible for monitoring tasks and for performing the actions

requested by the PF

During rotation for takeoff, the aircraft is pre-trimmed and the thrust is already set.

The initiation of a go-around involves a very dynamic sequence of actions and changes (i.e., thrust increase, configuration change) affecting the pitch balance.

When initiating a go-around at DA(H), the PF is expected to minimize the altitude loss.

Understanding the flight dynamicsof the go- around

Therefore, the PF must simultaneously apply a nose up pitch command on the control column (side stick) and trigger the go-around levers (set TOGA).

3 Nose Up effects:

By Elevator

By Thrust

By Flaps

• The PF should simply fly the aircraft while closely monitoring the PFD.

• If the pitch is not positively controlled, the pitch attitude continues to increase until a significant speed loss occurs, despite the go-around thrust.

Flying a manual go-around maneuver

For the PF:

• Toga• Rotation• PITCH COMMAND (typically 18 deg.)• Check power, performance• Announce FMA

• Flaps • FMA• Positive climb + L/G• Monitor A/C performance• Check FMA

For the PNF:

Strict adherence to the defined PF / PNF task sharing and to crew resources management principles are important.

The manual go-around technique must:

• Minimize the initial altitude loss;• Prevent an excessive pitch attitude by :

Following FD pitch commands (SRS orders), not exceeding 18-degrees pitch attitude ;

Considering a 25-degree pitch attitude as an ultimate barrier from which the pilot should return immediately.
