![]() They help to improve aircraft performance. Flaps –used during takeoff and landing phases of flight.The rudder is controlled by the left and right rudder pedals. The rudder is a moveable surfaced hinged to the vertical stabilizer or fin. Rudder – controls rotation about the vertical axis of an aircraft.The movement is referred to as “pitch.” Most aircraft have two elevators, one mounted on the trailing edge of each half of the horizontal stabilizer. Elevator – controls movement about the lateral axis of an aircraft.This movement is referred to as “roll.” Ailerons are attached to the outboard trailing edge of each wing and move in the opposite direction from each other. Aileron –controls movement about the longitudinal axis of an aircraft.Primary flight controls are required to safely control an aircraft during flight. Normal axis: Rotation around the normal axis is yawning and is controlled by the rudder.Lateral axis: Rotation around the lateral axis is pitching and is controlled by elevators or by a moving tailplane.Longitudinal axis: Rotation around the longitudinal axis is rolling and is controlled by ailerons, spoilers, or a combination of the two.Here are the basic rotation controls around 3 axises: Flight Control General Principlesįor steady flight, an airplane must be in a state of balance and the controls enable this to happen in all positions. In this article, we’ll take a birds eye’s view of flight controls to give you some insights into the general principles and terminology. Flight control systems are subdivided into primary and secondary flight controls. The most basic flight control system designs are mechanical and date back to the earliest aircraft. Flight control systems and characteristics can vary greatly depending on the type of aircraft you’re flying. Pilots use flight control systems to control the forces of flight and the aircraft’s direction and altitude.
