ENGINES ACCELERATION
Applicable to: ALL
When the pilot sets TOGA thrust for go-around, it takes some time for the engines to spool up due to the acceleration capability of the high by pass ratio engines. Therefore, the pilot must be aware that the aircraft will initially loose some altitude. This altitude loss will be greater if initial thrust is close to idle and/or the aircraft speed is lower than VAPP.

LEAVING THE GO-AROUND PHASE
Applicable to: ALL
The purpose of leaving the go-around phase is to obtain the proper target speed and proper predictions depending upon the strategy chosen by the crew. During the missed approach, the crew will elect either of the following strategies:
? Fly a second approach
? Carry out a diversion

SECOND APPROACH
If a second approach is to be flown, the crew will activate the approach phase in the MCDU PERF GO-AROUND page. The FMS switches to Approach phase and the target speed moves according to the flaps lever setting, e.g. green dot for Flaps 0.
The crew will ensure proper waypoint sequencing during the second approach in order to have the missed approach route available, should a further go-around be required.
DIVERSION
Once the aircraft path is established and clearance has been obtained, the crew will modify the FMGS to allow the FMGS switching from go-around phase to climb phase:
? If the crew has prepared the ALTN FPLN in the active F-PLN, a lateral revision at the TO WPT is required to access the ENABLE ALTN prompt. On selecting the ENABLE ALTN prompt, the lateral mode reverts to HDG if previously in NAV. The aircraft will be flown towards the next waypoint using HDG or NAV via a DIR TO entry.
? If the crew has prepared the ALTN FPLN in the SEC F-PLN, the SEC F-PLN will be activated, and a DIR TO performed as required. AP/FD must be in HDG mode for the ACTIVATE SEC F-PLN prompt to be displayed.
? If the crew has not prepared the ALTN FPLN, a selected climb will be initiated. Once established in climb and clear of terrain, the crew will make a lateral revision at any waypoint to insert a NEW DEST. The route and a CRZ FL (on PROG page) can be updated as required.
REJECTED LANDING
Applicable to: ALL
A rejected landing is defined as a go-around manoeuvre initiated below the minima.
Once the decision is made to reject the landing, the flight crew must be committed to proceed with the go-around manoeuvre and not be tempted to retard the thrust levers in a late decision to complete the landing.
TOGA thrust must be applied but a delayed flap retraction should be considered. If the aircraft is on the runway when thrust is applied, a CONFIG warning will be generated if the flaps are in conf full. The landing gear should be retracted when a positive climb is established with no risk of further touch down. Climb out as for a standard go-around.
