![]() Movement of any of the three primary flight control surfaces (ailerons, elevator or stabilator, or rudder), changes the airflow and pressure distribution over and around the airfoil. ![]() Wing flaps, leading edge devices, spoilers, and trim systems constitute the secondary control system and improve the performance characteristics of the airplane or relieve the pilot of excessive control forces.Īircraft control systems are carefully designed to provide adequate responsiveness to control inputs while allowing a natural feel.Īt low airspeeds, the controls usually feel soft and sluggish, and the aircraft responds slowly to control applications.Īt higher airspeeds, the controls become increasingly firm and aircraft response is more rapid. The ailerons, elevator (or stabilator), and rudder constitute the primary control system and are required to control an aircraft safely during flight.

This allows an aircraft to sustain its centre of gravity when dealing with uneven loads/weight.Īt Veritable Aerospace, owned and operated by ASAP Semiconductor, we can help you find all the flight control system parts you need for the aerospace, civil aviation, and defense industries. Elevator, rudder and aileron trim tabs are utilized to help a pilot counter effects of slip stream. This can be used to control airspeed when descending. When raised, spoilers are used to disrupt airflow over the wing and increase the amount of drag. Spoilers are similar to flaps and are located next to ailerons on the top of each wing. ![]() Flaps increase the camber of the wing airfoil, raising an aircraft’s lift coefficient. When flaps are extended, the stalling speed of an aircraft is reduced. Flaps are hinged surfaces on the trailing edge of the wings of a fixed-wing aircraft. The same would be true deflecting a rudder left, which would yaw the nose left.įlaps, spoilers and trim tabs are considered secondary flight control systems. Deflecting the rudder to the right will push the tail left and cause the nose to yaw right. Rudders are typically mounted on the back edge of the fin in the empennage. When raised, they push down on the tail and cause the nose to pitch up, giving an aircraft a higher angle of attack and more lift and drag. Elevators are mounted on the back edge of the horizontal stabilizer on each side of the fin in the tail. This deviation will lower one wing and raise the other, resulting in a turn. When raised, they reduce lift and when lowered, increase lift. Ailerons are mounted on the trailing edge of each wing near the wingtips and are used to turn during flight. Primary flight control systems include aircraft ailerons, elevators and rudders. Aircraft flight control systems are comprised of aircraft control surfaces, cockpit controls, connecting linkages and various operating mechanisms such as flaperon parts, bellcranks, pulleys and cables. In this article, we will go over primary flight control and secondary flight control systems to give an overview of how flight control systems accomplish aerial navigation. Once flight is achieved, aircraft flight controls give a pilot the ability to direct an aircraft. Aircraft Flight Control Systems-Primary and Secondary
