This is the speed at which drag is minimised. For jet aircraft, "long-range cruise" speed (LRC) is defined as the speed which gives 99% of the maximum range, for a given weight. This results in a 3–5% increase in speed. [8] It is also a more stable speed than maximum range speed, so gives less autothrottle movement. [9]
The Boeing 747-8 is the final series of the large, long-range wide-body airliners in the Boeing 747 family from Boeing Commercial Airplanes. The 747-8 is the largest variant of the 747 and Boeing 's largest aircraft. After introducing the 747-400, Boeing considered larger 747 versions as alternatives to the proposed double-deck Airbus A3XX ...
Concorde had a maximum cruising altitude of 18,300 metres (60,000 ft) and an average cruise speed of Mach 2.02 (2,150 km/h; 1,330 mph), more than twice the speed of conventional aircraft. [ 138 ]
2003 [2] –2021 [1] Introduction date. 25 October 2007 with Singapore Airlines. First flight. 27 April 2005; 19 years ago (2005-04-27) The Airbus A380 is a very large wide-body airliner, developed and produced by Airbus. It is the world's largest passenger airliner and the only full-length double-deck jet airliner.
The Boeing 747 is a long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2023. After the introduction of the 707 in October 1958, Pan Am wanted a jet 2+1⁄2 times its size, to reduce its seat cost by 30%. In 1965, Joe Sutter left the 737 development program to design the 747.
The Gulfstream G650 is a large business jet produced by Gulfstream Aerospace. [3] The model is designated Gulfstream GVI in its type certificate. [4] The aircraft can be configured to carry from 11 to 18 passengers over a range of 7,000 nautical miles [nmi] (13,000 km; 8,100 mi) at a top speed of Mach 0.925 (530.6 kn; 982.7 km/h; 610.6 mph ...
The de Havilland DH.106 Comet is the world's first commercial jet airliner. Developed and manufactured by de Havilland in the United Kingdom, the Comet 1 prototype first flew in 1949. It features an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wing roots, a pressurised cabin, and large windows. For ...
During the late 1990s, Boeing considered replacement aircraft programs due to slowing sales of the 767 and 747-400.Two new aircraft were proposed. The 747X would have lengthened the 747-400 and improved efficiency, and the Sonic Cruiser would have achieved 15% higher speeds (approximately Mach 0.98) while burning fuel at the same rate as the 767.
