The US Federal Aviation Administration defines a large aircraft as any aircraft with a certificated maximum takeoff weight (MTOW) of more than 12,500 lb (5,700 kg) [1] The European Aviation Safety Agency (EASA) defines a large aircraft as either "an aeroplane with a maximum take-off mass of more than 12,566.35 pounds (5,700.00 kilograms) or a ...
The analogous term for rockets is gross lift-off mass, or GLOW. MTOW is usually specified in units of kilograms or pounds. MTOW is the heaviest weight at which the aircraft has been shown to meet all the airworthiness requirements applicable to it. It refers to the maximum permissible aircraft weight at the start of the takeoff run. [1]
Wing loading is a useful measure of the stalling speed of an aircraft. Wings generate lift owing to the motion of air around the wing. Larger wings move more air, so an aircraft with a large wing area relative to its mass (i.e., low wing loading) will have a lower stalling speed.
The American Federal Aviation Administration defines a large aircraft as any aircraft of more than 12,500 pounds (5.7 tonnes) maximum certificated takeoff weight. [ 1 ] The European Aviation Safety Agency (EASA) defines a large aircraft as either "an aeroplane with a maximum take-off mass of more than 5,700 kilograms (12,600 pounds), a multi ...
Aircraft with thrust-to-weight ratio greater than 1:1 can pitch straight up and maintain airspeed until performance decreases at higher altitude. [3] A plane can take off even if the thrust is less than its weight as, unlike a rocket, the lifting force is produced by lift from the wings, not directly by thrust from the engine.
For instance, the aircraft described by the black altitude envelope on the right can fly at altitudes up to about 52,000 feet (16,000 m), at which point the thinner air means it can no longer climb. The aircraft can also fly at up to Mach 1.1 at sea level, but no faster. This outer surface of the curve represents the zero-extra-power condition ...
The intercontinental models had more fuel capacity, and had an MTOW of up to 315,000 lb (143 t); it was powered by JT4As for the Series 30, and by Rolls-Royce Conway turbofans for the Series 40. The Pratt & Whitney JT3D powered the later DC-8-50 and Super 60 (DC-8-61, -62, and -63) as well as freighter versions, and reached a MTOW of 325,000 lb ...
