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.

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.
Starting in the fall of 2020, Boeing found previous quality defects at multiple joins inside 787 fuselages that stopped almost all deliveries of the jet through August 2022, racking up more than $6.3 billion in additional “abnormal costs.”
We are fully confident in the safety of the 737 MAX, in the updates, and in the work technicians performed while these planes were on the ground: Updating the plane with the latest FAA-approved flight deck software. Rewiring the aircraft. Opening and inspecting the fuel tanks.
“If you could book a 737 500, and you find out it's a 737 MAX, technically they don't have to honor your request. … So you don't have a right to specify you are not going to go on a 737 MAX.”
A pilot's perspectiveSmith added that the 757 could get off the ground at a lower speed and use less runway than the 737, making it easier to operate for pilots flying out of smaller airports. Furthermore, the addition of winglets decreased the issue of wake turbulence that earlier 757s were known to generate.
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.
The Boeing 737 MAX aircrafts are returning to the skies. If there is an aircraft that you want to avoid it is this one. The 737MAX has been responsible for the deaths of 346 people in 2 separate plane accidents.
The A320's fly-by-wire technology was not only a way of improving flight controls and reducing weight. It enabled Airbus to take safety to a new level by introducing the flight envelope protection.
