Boeing 747-400 specs, size & range

The Boeing 747-400 is a landplane with 4 jet engines built by Boeing. Air-traffic control and flight-tracking sites identify it by the ICAO type code B744, while airline timetables and booking sites use the IATA code 744. It belongs to the heavy wake-turbulence category, so aircraft landing or taking off behind it must keep extra separation.
