Aircraft control

Definition

Aircraft control refers to the mechanisms and processes that allow a pilot or an automatic system to direct an aircraft's flight path. This includes the use of control surfaces like ailerons, elevators, and rudders, as well as systems for stabilizing and adjusting the aircraft's attitude in response to various inputs. Effective aircraft control is crucial for maintaining safe and efficient flight operations, especially in complex maneuvers or challenging conditions.
