Which aircrafts use fly-by-wire?

First developed on military aircraft and on Concorde, fly-by-wire technology has equipped all Airbus aircraft including A220 since the first A320, back in 1988 and the most modern version of concurrent aircraft, such as the B777, B787 and Embraer E-jets.

No. Fly-by-wire implies and denotes complete disconnection from the mechanical systems in the cockpit. The pilots fly the computers and the computers fly the airplane. The 737 is, really, the only airliner in current manufacture that does not feature fly-by-wire, although in the case of the 747–8, it is partial.

Airbus Flight Control Systems. Airbus aircraft designs subsequent to the A300/A310 are almost exclusively controlled by fly-by-wire equipment. These newer aircraft, including the AIRBUS A-320, A330 Family, A340 Family, A350 and AIRBUS A-380-800 operate under Airbus flight control laws.

These command signals are input to the 757 Flight Control Computers (FCC) or autopilots (described below under Airplane Modifications) which have been modified to act as fly-by-wire (FBW) computers where the pitch control laws are computed.

However, the 737 MAX extended spoilers are fly-by-wire controlled. Most of the systems are carried from the 737NG to allow for a short differences-training course to upgrade flight crews. In addition to the Speed Trim System (STS), the automatic stabilizer control system has been enhanced to include MCAS.

Yes, the Boeing 747–400 is a fly-by-wire airliner.

While the 757 program had been financially successful, declining sales in the early 2000s threatened its continued viability. Airlines were again gravitating toward smaller aircraft, now mainly the 737 and A320, because of their reduced financial risk.
