Before going into jabbara's controversial version, I'll need to understand fully gAMbl3 and vilas version that do concur with Airbus version stated in FCTM > OP >020> Normal Law.
I understand that beta target requires from us to center it with rudder to minimize drag and get max performance in case of high engine thrust.
Does that mean that when we are maintaining level flight before glide interception N-1, clean configuration, Airbus think that rudder deflection is not primordial and thus no beta target necessary?
Same question with engine failure in cruise, while applying drift down procedure : we'll have high engine thrust on one side, performance issues due to mountains , but... no beta target to request any rudder help from us.
Do we assume in those 2 cases that FAC & normal law compensation is simply sufficient ??
