Furthermore, increasing the drag it helps to reduce the braking time. ĭuring landing and after touchdown, the full extent of the spoilers and air brakes, causing a dramatic loss of lift so that the weight of the airplane applied to the wheels and reducing the case of slipping. In jet aircrafts, spoilers are used in combination with ailerons to control roll. On propeller airplanes the propellers can be used as air brakes themselves by changing their turning step. Another type of air brakes is the parachute as in the case of the Boeing B-47. For example, the air brakes of the Bombardier CRJ900 located at the end of the fuselage on the tail of the airplane, which is divided in half and opens outwards. There are many types in different airplanes. The spoilers are at the top of the wings and used in most jet as air brakes. The air brakes differ from the spoilers in the fact that air brakes increase the drag and lift, while spoilers reduce lift and it requires greater angle of attack to maintain it. From autopilot to electromechanical actuators and inertial sensors, Safran Electronics & Defenses Automatic Flight Control Systems (AFCS) improve the. Īir brakes / speed brakes are the control surfaces that we use on a airplane to increase the drag exerted on it, so to reduce its speed. In larger airplanes, except the tilt of flaps, there is also the expansion of flaps, that increasing the surface of the wing and making bigger the lift and drag. 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. 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.
