Boeing 747-300 specs, size & range

The Boeing 747-300 is a landplane with 4 jet engines built by Boeing. Air-traffic control and flight-tracking sites identify it by the ICAO type code B743, while airline timetables and booking sites use the IATA code 743. It belongs to the heavy wake-turbulence category, so aircraft landing or taking off behind it must keep extra separation.

The 747-300 is 70.60 m (231.6 ft) long, has a wingspan of 59.60 m and stands 19.30 m tall. That makes it the #6 longest of 67 airliners & big jets in our database — longer than 87% of them. With 511.0 m² of wing, the wing loading at maximum weight is about 739 kg/m².

747-300 weight and fuel

The maximum take-off weight is 377,842 kg (832,998 lb) and it may land at up to 285,762 kg — 76% 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 #4 of 69 by weight. Without fuel it may weigh at most 247,207 kg, leaving up to 130,635 kg for fuel at maximum take-off weight. The tanks hold 199,158 litres (52,612 US gallons), about 159.3 tonnes of jet fuel.
