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 ...
It is the world's largest passenger airliner and the only full-length double-deck jet airliner. Airbus studies started in 1988, and the project was announced in 1990 to challenge the dominance of the Boeing 747 in the long-haul market. The then-designated A3XX project was presented in 1994; Airbus launched the €9.5–billion ($10.7–billion ...
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 round-the-world flight took 35 hours and 54 minutes over 23,125 miles. [5] In 1976 a Boeing 747SP (ZS-SPA) of South African Airways was flown non-stop from the Boeing Company factory in Seattle to Cape Town during its delivery flight. This was a world record for an un-refueled commercial aircraft, this record was held for over a decade.
The Grob Strato 2C was a German experimental high altitude research aircraft. Powered by two turbocharged piston engines and featuring an extremely long span wing of composite construction, one aircraft was built in the 1990s, but was abandoned despite setting a world altitude record for piston-engined aircraft on its last flight.
On 17 December 2023, COMAC signed a deal with Tibet Airlines to jointly develop the high-altitude version of the jet in order to serve passengers in the Tibetan-Himalayan plateau. [ 83 ] The shortened version of the C919 is anticipated to serve routes with high-altitude landing sites, with a typical seating range of 140 to 160 passengers. [ 84 ]
The aircraft was the largest and fastest passenger plane at that time and also had the longest range, at 10,900 km (6,800 mi). It has held the official title of fastest propeller-driven aircraft since 1960. [2] [3] Due to its swept wing and powerplant design, the Tu-114 was able to travel at speeds typical of modern jetliners, 880 km/h (550 mph).
