The AN-72 is a light short takeoff and landing jet transport airplane intended for operations on non-equipped air strips 600 m long. Powerful wing high-lift devices and improved thrust-to-weight ratio ensure the airplane’s short takeoff and landing capability. The engines installed above the wing upper surface provide lift augmentation at takeoff and landing owing to the wing and wing center section flaps upper surface blowing with the engine exhaust jets (Coanda effect). The AN-72 was serially manufactured at the Kharkiv Aircraft Manufacturing Company where 114 airplanes of this type were built between 1984 and 1992. Activate group 1- Engine 1 starts.
