What does the term 'Alpha Prot' refer to?

The term 'Alpha Prot' specifically refers to a maximum angle of attack protection feature designed to prevent the aircraft from exceeding its critical angle of attack, which is the angle at which stall occurs. By implementing this protection mode, the flight control computers can automatically limit the maximum angle of attack the aircraft can achieve during flight. This is crucial for maintaining safe flight conditions and preventing stalls, especially during critical phases such as takeoff and landing.

This feature is part of the aircraft's flight control laws, and it serves to enhance safety by allowing the pilot to focus on other aspects of flying without the constant worry of inadvertently approaching a stall condition. The system engages to protect against flight situations that could otherwise lead to a loss of control due to excessive angle of attack.
