Final answer:
The bank angle is typically limited to less than 67 degrees when high angle of attack protection is active. This safety measure ensures the aircraft does not stall during aggressive maneuvering. The bank angle is a critical factor in the balance of lift forces during flight.
Step-by-step explanation:
When discussing flight control laws and high angle of attack protection, it's important to understand that modern aircrafts are designed to maintain safe operating conditions during flight. High angle of attack (AoA) protection is an advanced feature found particularly in fly-by-wire aircraft systems, like those on an Airbus or advanced military jets, designed to prevent the aircraft from stalling. When this protection is active, it limits the aircraft's maneuverability to ensure that the angle of attack does not exceed a safe threshold.
The bank angle during high AoA protection is usually constricted to prevent the aircraft from reaching critical angles that could induce a stall or other undesirable aerodynamic states. Typically, when the high angle of attack protection system is active, it will automatically limit the bank angle to less than 67 degrees. This is to reduce the risk of a stall during aggressive turning maneuvers at high angles of attack by making sure that some lift is always directed downwards to support the weight of the aircraft.
To clarify how lift and banking relate, consider this: When an airplane banks, there is a trade-off between the horizontal component that drives the turn and the vertical component that counters the weight of the airplane. In a balanced turn, these components are adjusted so that the airplane can safely maneuver without losing altitude. The degree to which an airplane can bank without compromising safety is determined by various factors including speed, wing configuration, and the design of the control laws that govern the aircraft systems.
