PREFACE
Applicable to: ALL
Failure to recognize the need for and to execute a go-around, when required, is a major cause of approach and landing accidents. Because a go-around is an infrequent occurrence, it is important to be "go-around minded". The decision to go-around should not be delayed, as an early go-around is safer than a last minute one at lower altitude.
CONSIDERATIONS ABOUT GO-AROUND
Applicable to: ALL
A go-around must be considered if:
? There is a loss or a doubt about situation awareness
? If there is a malfunction which jeopardizes the safe completion of the approach e.g. major navigation problem
? ATC changes the final approach clearance resulting in rushed action from the crew or potentially unstable approach
? The approach is unstable in speed, altitude, and flight path in such a way that stability will not be obtained by 1 000 ft IMC or 500 ft VMC.
? Any GPWS, TCAS or windshears alert occur
? Adequate visual cues are not obtained reaching the minima.
AP/FD GO-AROUND PHASE ACTIVATION
Criteria: SA
1 Applicable to: MSN 0045-0478, 0486-0499
The go-around phase is activated when the thrust levers are set to TOGA, provided the flap lever is selected to Flap 1 or greater. The missed approach becomes the active F-PLN and the previously flown approach is strung back into the F-PLN.
For the go-around, the appropriate flying reference is the attitude, since it is dynamic manoeuvre. So, if the "bird" is ON, the PF will ask the PNF to select HDG/VS, in order to remove the "bird". This also permits to replace the FPD by the FD bars, if the flight director is in use.
If the autopilot or the flight director is in use, SRS and GA TRK modes engage.
If the autopilot and both flight directors are off, the PF will maintain 15 ° of pitch.
If TOGA thrust is not required during a go-around for any reason, e.g. an early go-around ordered by ATC, it is essential that thrust levers are set to TOGA momentarily to sequence the F-PLN. If this is not done, the destination airfield will be sequenced and the primary F-PLN will become PPOS - DISCONT¬.

2 Applicable to: MSN 0480, 1668-4078
The go-around phase is activated when the thrust levers are set to TOGA, provided the flap lever is selected to Flap 1 or greater. The FDs bars are displayed automatically and SRS and GA TRK modes engage. The missed approach becomes the active F-PLN and the previously flown approach is strung back into the F-PLN.
For the go-around, the appropriate flying reference is the attitude, since it is dynamic manoeuvre. This is why, if the "bird" is ON, it is automatically removed, and the FD bars automatically replace the FPD. If TOGA thrust is not required during a go-around for any reason, e.g. an early go-around ordered by ATC, it is essential that thrust levers are set to TOGA momentarily to sequence the F-PLN. If this is not done, the destination airfield will be sequenced and the primary F-PLN will become PPOS - DISCONT
