The Boeing 777-300ER is a landplane with 2 jet engines built by Boeing. Air-traffic control and flight-tracking sites identify it by the ICAO type code B77W, while airline timetables and booking sites use the IATA code 77W. It belongs to the heavy wake-turbulence category, so aircraft landing or taking off behind it must keep extra separation.

777-300ER size and dimensions

The 777-300ER is 73.86 m (242.3 ft) long, has a wingspan of 64.80 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 795 kg/m².

777-300ER weight and fuel

The maximum take-off weight is 340,194 kg (749,998 lb) and it may land at up to 251,290 kg — 74% 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 #10 of 69 by weight. Without fuel it may weigh at most 239,250 kg, leaving up to 100,944 kg for fuel at maximum take-off weight.

777-300ER speed and range

It cruises at about 893 km/h (482 knots), faster than 57% of airliners & big jets. Its range of 13,649 km (7,370 nm) is enough to fly non-stop from London to Singapore (10,880 km) — about 15.3 hours at cruise speed. On final approach it flies at around 149 knots (276 km/h), which puts it in ICAO approach category D. Its ceiling is 43,100 ft (13,137 m).
