To return to the thread:
but why would you ever want the Go Around mode during the Climb phase, if its all to do with phase ?
Observed in a simulator recently during an EFAV1 exercise:
After controlling the aircraft through the engine failure (without selecting TOGA) and before engaging AP the captain calls "Pull heading".
The co-pilot pulls altitude instead so the aircraft goes into OPEN CLIMB.
Suddenly no SRS and no V2 indication on PFD.
Captain engages AP, sets TOGA (SRS/GATRK) and pulls heading himself. Fixed.
Q.E.D.
