Fixed-Wing Flight Control Systems

Maximize safety and reliability

Collins Aerospace offers fly-by-wire flight control systems for fixed-wing aircraft. These control systems enable automatic functions, such as aircraft stability and redundancy in both computers and electronics, to ensure safety and maximize reliability for flight, landing and take-off.

Our primary flight control systems drive the aircraft attitude in the sky by operating the flight surfaces with aileron, elevator and spoiler actuators, including our trimmable horizontal surface actuator (THSA).

Advanced fly-by-wire technologies include our electro-hydrostatic actuator (EHA) and electro-hydrostatic back-up actuator (EHBA). On these actuators, lift systems drive the flap and slats to increase the wing lift for landing and take-off.

EHA technology is transitioning toward more electrical technology, such as electro-mechanical actuators. The actuator commands and power are electrical, but are used to directly operate a mechanical gear transmission without hydraulic fluid.
