Good morning!
Thanks,
So if I mix your and Flight Detent's knowledge, it gives me this:
Flight Detent: When the plane reaches Vprot, the ELAC pitches down and maintains Vprot. We can override it by pulling up. The "plane" will pitch up and down to maintain Vprot
AF330: The plane? Hmm... But what If A/THR is OFF?
Dupre: ELAC will maintain Vprot. ELAC knows it's IAS and the plane's load factor. It maintains Vprot.
AF330: Ok...and what if A/THR ON at Vprot?
Dupre: ELAC has been programmed and knows if A/THR is ON or OFF. If A/THR is ON:
ELAC will pitch down at X° (programmed value). A/THR will keep managing the target speed TILL AoA Alpha floor where FAC's will ask to give A/THR full TOGA thrust.
AF330: What If we try to disconnect A/THR while Alpha floor?
Dupre: Here is what we can read on the FMA:
A.FLOOR - which means that we ARE at AoA Alpha Floor. We get TOGA from A/THR but we can't disconnect it.
TOGA LCK: We can disconnect A/THR - Even If we are at Vprot (Vprot protection will activate)
Do you agree with this now?
Just waiting for your confirmation!
Regards,
AF330
