The go-around phase is activated when the thrust levers are set to TOGA, provided the flap lever is at Flap 1 or greater. The FDs are displayed automatically.
The SRS provides guidance to either the speed at go-around engagement or VAPP, whichever is higher, until the acceleration altitude. The speed is further limited to maximum of VLS + 25 with all engines operative or VLS + 15 with one engine inoperative. If the go-around is manually flown, the initial pitch targets are 15. with all engines operative and 12.5. with one engine inoperative. If FPV/FPD has been used for the approach, it may be necessary to press the HDG V/S-TRK FPA.pushbutton.to.restore.pitch.and.roll.bars.
To initiate the go-around, the PF simultaneously applies TOGA thrust, announces the go-around, calls for the required flap setting and rotates to the required pitch attitude. Before moving the flaps, the PNF should check that the speed is greater than VLS and not reducing. For normal operations, the required flap setting is one step less than the approach configuration, e.g. Flap 3 following a Flap Full approach. If the go-around is carried out early in the approach with Flap 1 selected, do not retract flap until above S speed. PF then checks for correct FD presentation and once a positive ROC is confirmed requests landing gear retraction. Before making the requested configuration change, the PNF checks the required parameters and repeats the PF command. The PNF confirms that the correct thrust is set and then the PF reads the FMA and requests the required lateral modes (NAV or HDG). If the AP is engaged the PF can.make.the.lateral.mode.selection.

FCTM Go-around
GA TRK guides the aircraft on the track memorised at the time of TOGA selection. The missed approach route becomes the ACTIVE F-PLN provided the waypoints have been correctly sequenced on the approach. The previously flown approach is placed back into the F-PLN. If a second approach is required, it becomes available when the approach phase is re-activated. Pushing for NAV enables the missed approach F-PLN to be followed. If both APs had been engaged prior to the selection of TOGA, the go-around will be flown with both APs remaining engaged. Whenever any other mode engages, AP 2 disengages. The FMGS makes no predictions in the go-around phase. Consequently CLB mode.is.not.available.and.the.pilot.must.observe.constraints.
Subsequent procedures, including thrust handling and flap retraction, are in accordance with the take-off phase. FCTM Ch 4 refers. Thrust reduction and acceleration will be sequenced at the altitudes programmed in the PERF GA page.
A late go-around may result in ground contact. If touch down occurs after TOGA is engaged, the AP will remain engaged and the A/THR remains in TOGA. The ground.spoilers.and.autobrake.are.inhibited.
Go-Around.From.An.Intermediate.Approach.Altitude
To interrupt an approach, or perform a go-around from an intermediate altitude in the approach where TOGA thrust is not required, set the thrust levers to the TOGA detent and then retard them as required, normally back to the CL detent. Provided the flap lever is at Flap 1 or greater, the go-around mode will activate with the associated AP/FD modes. If the thrust levers are not briefly set to the TOGA detent, the FMGS will not engage the go-around phase, and flying within 7 nm of the airport will sequence the destination waypoint. In this case, the active F-PLN will be erased and only PPOS . F-PLN DISCONTINUITY will be displayed.
If necessary, select the applicable AP/FD and A/THR modes on the FCU to manage.the.subsequent.flight.profile.
LEAVING.THE.GO-AROUND.PHASE
During.the.missed.approach,.choose.either.of.the.following.strategies:
. Fly.a.second.approach . Carry.out.a.diversion
The chosen strategy will depend upon the reason for the go-around, e.g. poor weather. The purpose of leaving the go-around phase is to obtain the proper target.speed.and.predictions.for.the.chosen.strategy.
