GO AROUND (GA)
Go-around mode combines the speed reference system (SRS) vertical mode with the GA
TRK lateral mode.
ENGAGEMENT CONDITIONS
Setting at least one thrust lever to the TOGA detent engages both SRS/GA TRK modes,
if :
– The flaps lever is at least in position 1, and
– The aircraft is in flight, or
– The aircraft has been on the ground for less than 30 seconds (AP disengages and can
be re-engaged five seconds after lift-off).
– FD bars are automatically restored in SRS/GA TRK modes.
If FPV/FPD was previously selected, it reverts to FD bars.
The FMA displays “SRS” and “GA TRK” in green.
If aircraft is on the ground for
more than 30 seconds, then SRS engages, provided V2 is inserted in FMGC and at least Flap 1 selected.
See FCOM 1.22.30 P47 for SRS engagement conditions.
