A type of flight-control system where input command signals are sent to the actuators through the medium of optical-fiber lines. The feedback from the control surfaces and other systems is routed in a similar way. The inputs from the control column, aircraft control surfaces, and other data, such as static and dynamic pressure and angle of attack, are fed into a computer connected to fiber-optic lines. The computer then provides data for movement of the aircraft control surfaces through these cables.

Lucas has already demonstrated this technology, being the first company to supply a fly-by-light system on a passenger carrying aircraft.
5 million program, McDonnell Douglas Aerospace will lead 14 companies in an effort to speed development of fly-by-light and power-by-wire technology for use in military and commercial aircraft.
The FLASH program will develop three key elements of fly-by-light and power-by-wire technology: 1) a cost-effective and reliable fiber optic cable infrastructure to provide viable industry sources of components and systems; 2) a low-cost flight control system using fly- by-light sensors and control links, including new processes for control system design; and 3) fly-by-light/power-by-wire actuators that provide significant improvements in reliability and maintenance over current systems.
IPTN and Lucas have established a Scope of Work to identify specific areas of joint study for a fly-by-wire and fly-by-light flight control system and will utilize the IPTN N250 prototype aircraft number one as the platform to test the flight control configuration.
