Study Notes
Airplane Control Surfaces
-
Ailerons control the aircraft's roll (tilting the aircraft left and right) and are operated by the control wheel.
-
Stabilator controls the aircraft's pitch (nose up or down) and is operated by the control column.
-
Rudder controls the aircraft's yaw (turning the aircraft left or right around its vertical axis) and is operated by the rudder pedals.
Airplane Control Systems
-
Control Wheel is connected to the ailerons via cables and bellcranks which transmit the pilot's input to the ailerons.
-
Control Column connects to the stabilator via a cable and bellcrank.
-
Rudder Pedals connect directly to the rudder.
Trim Systems
-
Stabilator Trim allows the pilot to adjust the angle of the stabilator for a consistent aircraft pitch without having to hold the control column in a specific position. This can be adjusted with a wheel and drum or an electric trim control.
-
Rudder Trim allows the pilot to adjust the angle of the rudder for a consistent aircraft yaw without having to hold the rudder pedals in a specific position.
