My comments are strictly based on Airbus documents and I don't lay any claims to greatness. I am aware that some of the people who comment here have better qualifications than i have.
The way FCOM describes this chapter is responsible for some confusion. First these are protections and they are available only in normal law. What is described as load factor law or AOA law are in facts modes of normal law Valpha prot is the defining boundary. FCOM is quoted below
HIGH ANGLE OF ATTACK PROTECTION
Innormal law, when the angle-of-attack becomes greater than α PROT, the systemswitches the elevator control from normal mode to a protection mode, in which the angle-of-attack is proportional to sidestick deflection. That is, in the α PROT range, from α PROT to α MAX, the sidestick commands α directly. However the angle-of-attack will not exceed αMAX, even if the pilot gently pulls the sidestick all the way back. If the pilot releases the sidestick, the
angle-of-attack returns to α PROT and stays there.
I don't see where is the problem?
