Description: The Boeing 747 is a huge, short and long range, high capacity airliner intended primarily for intercontinental flights. This aircraft is capable of flying at Mach 0.85 carrying around 500 passengers. The first model, 747-100 ordered by Pan Am, entered service in 1970 with a take-off weight of 340-ton. Along with the -100 model, the 747-100B, -100SR for short range/high-capacity flights and -100SF freighter were introduced in 1970.

The Boeing 747-400 is the only 747 model in production incorporating major aerodynamic improvements over earlier models such as winglets to reduce drag. Along with major aerodynamic improvements, the 747-400 introduces new digital avionics, lightweight aluminum alloys, a new flight deck and entertainment systems. It is externally similar to 747-300 model.

The four-engine 747-400 can be powered alternatively by Pratt & Whitney PW4062, Rolls Royce RB211-524 or General Electric CF6-80C2 engines rated approximately at 60,000 pounds each. More than 240,000 pounds of thrust enable the 747-400 to travel at Mach 0.85 while performing intercontinental flights.

The Boeing 747-400ER airliner is an increased gross weight derivative of the 747-400. The additional weight allows to carry more fuel (up to two 3,060 gallons fuel tanks in the forward lower cargo compartment) to fly over longer ranges. It can carry between 416 to 524 passengers in a tri-class or two-class arrangement.

The first -400ER model was delivered to Qantas in 2002. It can be powered by PW4062 or CF6-80C2 engines.
