Ok...so more questions now!
1) If we hit Vfloor, A/THR gives TOGA. Can we exit leave A/THR at Vfloor (by pressing red button on levers e.g)?
2) So how does it happen? FAC knows Vfloor. FAC sends a signal to A/THR to give TOGA?
3) Well...confused for Vprot....
What maintains Vprot???? Is it FAC or ELAC? Your F-COM says:
" and not for flight control protection (the activation of the protections is computed by the ELAC)."
It's pretty confusing. It says that FAC only displays Vprot...etc. So just 1 question here:
Option 1: ELAC knows Vprot. It knows it's IAS, it knows it's attitude --> No need of FAC's. ELAC's are managing Vprot.
Option 2: ELAC knows nothing (of course, it does but does not take any decision itself), FAC knows Vprot, our IAS and the attitude --> It sends to ELAC pitch command to maintain Vprot.
Your F-COM tends to say that ELAC do it alone. Of course, FAC's do other things such as stoping trim at Vprot. (Normal Law)
What do you think? (Option 1 or 2?)
Thanks a lot!
