Commonly referred to as the 'Triple Seven,' the 777 is Boeing's first fly-by-wire airliner (an electronic system that replaces the conventional manual flight controls of an aircraft) and the first commercial aircraft entirely computer-designed.

Yes, the Boeing 777 was the first Boeing aircraft to utilize a full digital Fly-By-Wire (FBW) flight control system. Launched in 1994, it replaced traditional mechanical cables and pulleys with electronic interfaces. Pilot inputs from the yoke are converted into digital signals, which are then processed by three "triple-triple redundant" primary flight computers. These computers then send commands to hydraulic actuators at the control surfaces. One unique feature of the 777's FBW system is its "Envelope Protection," which prevents the pilot from making maneuvers that would overstress the airframe or cause a stall, though unlike Airbus, Boeing's system still allows the pilot to "override" the computers with enough force. In 2026, this system is lauded for its reliability and safety, as it uses three different types of microprocessors (Intel, Motorola, and AMD) to ensure that a software bug in one chip won't affect the entire flight control system.
