/ˌflaɪˌbaɪˈwaɪ(ə)r/

Etymology: < fly v.¹ + by prep. + wire n.¹ (compare wire n.¹ 9a).

Chiefly Aeronautics.

A. adj.

Designating an electrical system used (instead of mechanical connections) to control the flight of an aircraft or spacecraft; involving or relating to such a system. Also: designating a vehicle controlled by such a system. Cf. drive-by-wire adj.In a fly-by-wire system, the operation of the controls by the pilot is translated by an electronic interface into the movement of control surfaces (such as the rudder, ailerons, etc.) of the aircraft.

1955 Aeronaut. Electronics Digest 204/1 A movement of the pilot's joystick or column will only send an electrical signal to some sort of actuating device which will move the surface. Such arrangements for the lack of a more uniformly accepted term are considered fly-by-wire techniques.

1962 J. Glenn in J. Glenn et al. Into Orbit 195 I used the fly-by-wire mode which..utilizes a combination of the manual control stick and the hydrogen peroxide nozzles of the automatic system.

1981 U.S. Patent 4,274,808 6 Electromagnetic interference and lightning induced electromagnetic pulses are potential dangers to any fly-by-wire system.

2019 Daily Tel. (Nexis) 24 June 15 On a fly-by-wire aircraft the pilot's inputs are interpreted by the computer through a series of control laws that limit speed, G-force, the angle of bank and other parameters to maintain a safe flight path within the aircraft's limits.

B. n.

The use of electrical systems (instead of mechanical connections) for controlling the flight of an aircraft; a system of this type. Cf. drive-by-wire n.
