What are the aileron trailing edge traveling limits?

The correct answer indicates that the aileron trailing edge has a travel limit of 20 degrees up and 11 degrees down. This specification is crucial as it defines the maximum deflection of the ailerons, which are essential for controlling the roll of the aircraft. The upward motion of the ailerons contributes to reducing lift on that wing, allowing the aircraft to roll in the opposite direction. Conversely, the downward motion increases lift on the same wing, facilitating the desired roll.

The precise angles of travel are determined by the aircraft's design to ensure effective control while maintaining structural integrity and aerodynamic efficiency during various flight conditions. Understanding these limits is vital for pilots and technicians alike to ensure safe operation and adherence to the aircraft's handling characteristics.

In this context, knowing the exact travel limits helps in the operational and safety checks during pre-flight inspections and ensures that pilots are familiar with how much control surface response to expect during maneuvering.
