The allowable rolling angle of a civil airliner refers to the maximum angle at which the aircraft rotates around its longitudinal axis. The pilot changes the rolling angle of the plane by manipulating the side sliding of the aircraft. The rolling angle plays a crucial role in flight. It can help aircraft change course, avoid wind shear and turbulence, and perform aerobatic flight.
The allowable rolling angle range of civil airliners is usually between -20 degrees and +20 degrees. Within this range, the plane can safely turn, climb and descend. However, in actual flight, pilots rarely adjust the rolling angle of the aircraft to this fixed limit, because excessive rolling angle may damage the structure and flight safety of the aircraft.
The main reasons for the limitation of the rolling angle are as follows:
1. Structural strength of the aircraft: An excessive rolling angle may cause the aircraft structure to be subjected to excessive stress, thus affecting the life and safety of the aircraft.
2. Pilot's comfort: Excessive rolling angle will cause discomfort in the cockpit, which will affect the pilot's eyesight and accuracy.
3. Flight safety and stability: excessive horizontal roll affects flight safety.
The pilot controls the lateral rolling angle of the aircraft by manipulating the lateral slide. During the flight, the pilot needs to adjust the rolling angle of the aircraft in a timely manner according to the actual situation, such as weather conditions, route requirements, etc., to ensure the safety and comfort of the flight.
The impact of the rolling angle on flight safety and comfort cannot be ignored. Pilots need to be rigorously trained and master the horizontal rolling control of the aircraft to ensure that they can fly the aircraft safely and stably in all situations.
