The highest altitude obtained by an electrically powered aircraft is 29.524 kilometres (96,863 ft) on August 14, 2001, by the NASA Helios, and is the highest altitude in horizontal flight by a winged aircraft. This is also the altitude record for propeller driven aircraft, FAI class U (Experimental / New Technologies), and FAI class U-1.d ...
Ground effect and medium altitude transport Airbus A380-900: 2006: 580.68 tons Airbus A380-800 stretch, postponed in May 2010 [6] TsAGI HCA-LB: current: 984.21 tons Ground effect aircraft powered by LNG: WindRunner: current: Outsize cargo freight aircraft: 108 m long, 80 m wingspan. [7] [8]
Above the TA, the aircraft altimeter pressure setting is changed to the standard pressure setting of 1013 hectopascals (equivalent to millibars) or 29.92 inches of mercury, with the aircraft altitude will be stated as a flight level instead of altitude. In the United States and Canada, the transition altitude is 18,000 ft (5,500 m). [5]
A landing U-2 is accompanied on the ground by a chase car, which is driven by a second U-2 pilot who assists the landing U-2 by reporting the aircraft's altitude. [45] [46] In practice, once the aircraft has descended to an altitude of two feet (0.61 m) above the runway the pilot initiates a stall and the aircraft falls from this height. Chase ...
The X-15 set speed and altitude records in the 1960s, crossing the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, 4,520 miles per hour (7,274 km/h; 2,021 m/s), [ 1 ] was achieved on 3 October 1967, [ 2 ] when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet ...
Long-range intercontinental high-altitude strategic bomber prototype, designed to climb up to 16,000–17,000 m (52,000–56,000 ft). [63] It was a high-altitude version of the Tupolev Tu-95 aircraft with high-altitude augmented turboprop TV-16 engines and with a new, enlarged-area wing.
The Grob G 520 ‘EGRETT’ is a turboprop-powered long-endurance, high-altitude reconnaissance and surveillance aircraft designed and produced by the German aircraft manufacturer Grob Aircraft. Since September 1988, it has been the holder of several world records relating to altitude and time to climb.
The Bristol Type 138 High Altitude Monoplane was a British high-altitude single-engine, low-wing monoplane research aircraft developed and produced by the Bristol Aeroplane Company during the 1930s. It set nine world altitude records, with the maximum altitude achieved being 53,937 ft (16,440 m) on 30 June 1937, during a 2¼-hour flight.
