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 first 747-400 was delivered to Northwest in 1989. By default, its interior has a tri-class (416 passengers) arrangement but a two-class (524 passengers) or one-class configurations are also suitable for the -400 model. The -400D (Domestic) model is a high seating capacity intended for short range routes and was introduced in 1991. The 747-400 Combi has a main deck cargo door installed on the left side aft of the wing. The Combi model can be turned into an all passengers or a passenger/cargo aircraft.
