The pilot controls the flight controls.
Flight controls are the mechanisms that allow the pilot to maneuver an aircraft. These controls include the yoke or stick, rudder pedals, throttle, and ailerons, elevators, and rudder.
The yoke or stick controls the ailerons and elevators, which are responsible for rolling and pitching the aircraft, respectively.
The rudder pedals control the rudder, which is used for yawing the aircraft.
The throttle controls the engine power, which affects the aircraft's speed and altitude.
The pilot's actions on these controls are translated into movements of the aircraft's control surfaces, which in turn alter the airflow over the wings and tail, resulting in changes in the aircraft's attitude and direction.
In addition to the pilot, flight controls can also be controlled by autopilot systems, which are designed to maintain a specific heading, altitude, and speed.
Autopilots are typically used during long flights to reduce pilot workload and improve safety.
Modern aircraft also have fly-by-wire systems, which use electronic signals to control the flight controls instead of mechanical linkages. This allows for more precise control and can also help to prevent pilot error.
