Final answer:
The rudder trim reset pushbutton is typically deactivated when the rudder is in a neutral position. This is to protect against accidental resets during important flight operations.
Step-by-step explanation:
The rudder trim reset pushbutton is generally deactivated when the rudder is in a neutral position.
The reason behind this is to prevent the rudder trim from being reset unintentionally during flight operations when the rudder is being actively used to control the aircraft's yaw. It is designed this way to preserve the intended rudder trim setting during critical phases of flight, such as takeoff and landing, which ensures the safety and stability of the aircraft.
