how to trigger Go-around mode A320
it was on the sim last week. after taking off with one engine on fire, i maintained the runway heading with thrust at MCT detent. everything was ok since it was leveled off at 1500 AGL, then i tried to retract the flap, but the accelerating was slow. then i decided to forward the thrust to TOGA. Strange thing happaned , i triggered the GA mode. FMA displayed TOGA, SRS GA TACK.
Could anyone tell me, the reasons for this? i was on runway heading, it should not happen. |
DSC-22_30-80-40:
Setting at least one thrust lever to TOGA detent engages both SRS/NAV modes if:
Your flap lever was in position 1 (or more), so TOGA engaged GA mode. |
Could anyone tell me, the reasons for this? |
If you want to use TOGA, select it before ACC ALT. After ACC ALT you are out of "Take off mode" (FMGS). With the above mentioned requirements and selecting TOGA, the FMGS thinks you initiating a Go Around. So select TOGA before ACC ALT.

....but it's not a problem if you do select TOGA during acceleration.
Read FMA (MAN TOGA/SRS/GA TRK). Think "is this what I want?" MAN TOGA - Yes SRS -. No, so 'Push to Level Off' (again) and check FMA reads 'VS 0' GA TRK - No, so pull 'Hdg' and check FMA reads 'HDG' Yellow Speed Trend Arrow now much longer!! It's all in the FMA! Cheers mcdhu |
got it cheers

actually i did what u said. what confused me is why the GA mode been triggered during take off.

I'm not sure on that, but MAYBE G/A was triggered because with MCT, A/THR was already out of the two possible T/O modes (TOGA&FLX) Cheers |
