What triggers the bank angle protection to activate?

1. Bank angle exceeds 35º

2. Thin air conditions

3. Flap configuration

4. Low fuel levels

The correct answer is: Bank angle exceeds 35º

The activation of bank angle protection is specifically designed to enhance safety during flight by preventing excessive bank angles that could lead to loss of control. When the bank angle exceeds 35 degrees, the aircraft’s flight control system intervenes to limit further bank increase. This protection system is crucial for maintaining the aircraft's stability and ensuring that pilots do not unintentionally enter a situation that could lead to a stall or uncontrolled dive. The other options, while relevant to various aspects of flight operations, do not directly initiate bank angle protection. Thin air conditions might impact lift and performance but are not directly tied to bank angle restrictions. Flap configuration affects the aircraft's aerodynamic characteristics, influencing airflow and lift but does not trigger bank angle protection. Low fuel levels are a critical operational consideration but do not dictate bank angle limits or activation of protective measures. Therefore, the correct answer reflects the specific condition that directly activates this crucial safety feature.
