The Boeing 777-300 is a landplane with 2 jet engines built by Boeing. Air-traffic control and flight-tracking sites identify it by the ICAO type code B773, while airline timetables and booking sites use the IATA code 773. It belongs to the heavy wake-turbulence category, so aircraft landing or taking off behind it must keep extra separation.

777-300 size and dimensions

The 777-300 is 73.86 m (242.3 ft) long, has a wingspan of 60.90 m and stands 18.50 m tall. That makes it the #4 longest of 67 airliners & big jets in our database — longer than 93% of them. Its fuselage is 6.20 m wide, wide enough for a twin-aisle cabin. With 427.8 m² of wing, the wing loading at maximum weight is about 700 kg/m².

777-300 weight and fuel

The maximum take-off weight is 299,370 kg (659,997 lb) and it may land at up to 237,682 kg — 79% of take-off weight, so after a short flight it has to burn off fuel before landing at full weight. Among airliners & big jets it ranks #15 of 69 by weight. Without fuel it may weigh at most 224,528 kg, leaving up to 74,842 kg for fuel at maximum take-off weight.

777-300 speed and range

It cruises at about 893 km/h (482 knots), faster than 57% of airliners & big jets.
