Design

Engines, extended slats, flaps, and landing gear of an American Airlines 777-200ER

Boeing introduced a number of advanced technologies with the 777 design, including fully digital fly-by-wire controls,^[114] fully software-configurableavionics, Honeywell LCD glass cockpit flight displays,^[115] and the first use of a fiber optic avionics network on a commercial airliner.^[116] Boeing made use of work done on the cancelled Boeing 7J7 regional jet,^[117] which utilized similar versions of the chosen technologies.^[117] In 2003, Boeing began offering the option of cockpit electronic flight bag computer displays.^[118]

[edit]Fly-by-wire

In designing the 777 as its first fly-by-wire commercial aircraft, Boeing decided to retain conventional control yokes^[114] rather than change to sidestickcontrollers as used in many fly-by-wire fighter aircraft and in many Airbus airliners.^[114] Along with traditional yoke and rudder controls, the cockpit features a simplified layout that retains similarities to previous Boeing models.^[119] The fly-by-wire system also incorporates flight envelope protection,^[114] a system that guides pilot inputs within a computer-calculated framework of operating parameters, acting to prevent stalls and overly stressful maneuvers.^[114] This system can be overridden by the pilot in command if deemed necessary.^[114]
