The angle of bank is controlled by which axis?

The angle of bank refers to the tilt of the aircraft about its longitudinal axis, which runs from the nose to the tail. When a pilot initiates a turn, the aircraft's wings are banked relative to the horizontal plane. This banking motion is essential for the aircraft to change direction while maintaining lift and control.

The longitudinal axis is directly involved in controlling the roll of the aircraft, which is what the angle of bank represents. As the aircraft rolls to one side or the other about this axis, it effectively changes the direction of flight, allowing the aircraft to turn. Understanding this concept is crucial for pilots in managing turns effectively and ensuring safe maneuvering through various phases of flight.
