Operational Context

Boeing 777-300 — high-capacity widebody twinjet

The 777-300 first flew in 1997 and entered service in 1998. It features an extended fuselage compared with the 777-200, allowing additional seating. The aircraft retains the widebody twin-engine layout and advanced flight deck systems introduced with the 777 program.

Powered by two high-bypass turbofan engines producing up to approximately 94,000 pounds of thrust (418 kN) each depending on engine option, the 777-300 cruises at around 490 knots (905 km/h). Maximum takeoff weight exceeds 660,000 pounds (299,370 kg). Seating typically ranges from 350 to over 450 passengers depending on configuration.

The 777-300 laid the groundwork for the later 777-300ER. It enabled airlines to serve high-demand routes efficiently with twin-engine economics. The model remains an important member of the 777 family history.
