In most smaller airplanes, this is achieved by increasing the angle at the rear of the wing by a simple tilt of flaps in correct degrees (plain flaps). The main objective is to increase the lift and drag of the wings. There are several types of flaps, depending on the size, the complexity and the speed of the aircraft. In some other cases, depending on the type of flaps and the position of the wing, their extension may increase the pitch of the aircraft. In some aircrafts, the use of flaps helps to reduce the angle of tilt of the longitudinal axis (pitch), aiding the pilot to have a better view of the runway. In a similar way can reduce the distance on the runway during takeoff, as they allow the aircraft to fly at slower speed. So when using the flaps, we can reduce the speed at which a stall occurs, resulting to have slower approach to the runway, and therefore a shorter distance for safe landing. Ailerons, elevators and rudders are considered primary flight control surfaces.Flaps are located to the back of the wings of an airplane and are used to reduce the speed with which the airplane can fly safely. These are all secondary flight control surfaces, however. Alternative flight control surfaces consist of spoilers, flaps, slaps and air brakes. While ailerons, elevators and rudders are the most common types of flight control surfaces, airplanes may include others as well. When a pilot presses the right pedal, conversely, the airplane’s rudder will move to the right. When a pilot presses the left pedal, the airplane’s rudder will move to the left. The rudder is controlled by a pair of pedals inside of the cockpit. Most airplanes have a single rudder, which is mounted to the back edge of the vertical stabilizer. ![]() We can’t talk about flight control surfaces without mentioning rudders. Both of the elevators will move up together, and they’ll move down together. Unlike with ailerons, elevators operate in sync with each other each. You can find them affixed to the horizontal tail of an airplane. Elevators are adjustable parts of the horizontal stabilizer. This alternating positioning will then change the direction of the airplane, essentially turning the airplane to the left.Īnother common type of flight control surface is an elevator. Normally, when pilots move the control stick to the left, the aileron on the left wing goes up while the aileron on the right wing does down. Most airplanes have a single aileron on the back of each wing. Ailerons consist of horizontal and rectangular-shaped tabs that are fitted to the back of an airplane’s wings. Ailerons, for instance, are a common type of flight control surface. There are several types of flight control surfaces. Secondary flight control surfaces are supplemental devices that assist in the aforementioned flight processes. Primary flight control surfaces are the most important, and airplanes rely on them during takeoffs and landings. ![]() Most airplanes have a combination of primary and secondary flight control surfaces. What are flight control surfaces exactly? Also known as a flight control system, a flight control surface is an aerodynamic device that’s used to change an airplane’s speed, trajectory or altitude. They allow pilots to change the speed or trajectory of an airplane through adjustments performed in the cockpit. These adjustable areas are flight control surfaces. While some of these areas are fixed, others are adjustable. Airplanes are designed to generate lift in response to air flowing under and over certain areas. Flight control surfaces are an important part of all airplanes.
