Parker Aerospace fly-by-wire (FBW) primary and secondary flight control actuators have demonstrated highly reliable, fault-tolerant, precise position-control solutions for commercial and military applications for decades.

Fly-by-wire flight control actuators receive signals from the flight control computer and convert them into control surface motion for optimal flight control and flying qualities. Parker Aerospace FBW actuators have proven reliability and performance records on a wide variety of commercial, military, and business jet aircraft.

FBW actuators feature Parker's Jet-Pipe® electrohydraulic servovalve technology or direct drive valve technology along with the latest developments in fly-by-wire technology. Today's aircraft manufacturers rely on fly-by-wire for improved performance, reliability, and weight savings gained through the elimination of the control linkages necessary with mechanical input actuation.

The fly-by-wire actuators use the latest technology, materials, and coatings for failsafe and reliable performance over the entire service life. Our proven design tools and engineering teams optimize the packaging for envelope and weight.

APPLICATIONS:  
Fly-by-wire actuators use signals from the pilot via the aircraft's flight control system to control flight control surfaces along the vertical (pitch), longitudinal (roll), and horizontal (yaw) axes for safe and coordinated flight. Fly-by-wire flight control actuation is used by helicopters, military aircraft, commercial transports, regional jets, and business jets.
