okay. The conditions are ,final approach,current altitude higher than acceleration altitude and fcu altitude set to missed approach alt which is lower than current altitude. WE put TOGA,briefly, FMA flashes LVR CLB as alt is above GA thr reduction altitude. as flaps are not 0 fmgc goes to GA phase.Fma roll mode changes to NAV(new fms2) ,we bring back thr levers to clb detent quickly.
Now the sweetspot.
DISENGAGEMENT CONDITIONS
The SRS mode disengages :
Automatically,
- at the Go-around acceleration altitude (GA ACC ALT), or
- if ALT* mode engages (above 400 feet RA).
Pitch mode should not remain SRS as we are above GA acceleration altiude, fma roll mode will be current VS and ALT blue. and thrust will be SPEED due pitch mode.
Therefore, no issue if atc tells us to go missed at high alt. simply select speed to higher than vapp, as desired, the aircraft will automatically level off at the lower missed app altitude. The aircraft will NOT go into SRS and therefore shall not climb, but will descend with current V/S. There will be a momentary speed increase as we go to TOGA but will return with SPEED mode engaging.
