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 ...
Hence, the aircraft will not have any excess capacity to climb further. Stated technically, it is the altitude where the maximum sustained (with no decreasing airspeed) rate of climb is zero. Compared to service ceiling, the absolute ceiling of commercial aircraft is much higher than for standard operational purposes.
The rule affected only those aircraft operating under IFR when in level flight above 3,000 ft above mean sea level, or above the appropriate transition altitude, whichever is the higher, and when below FL195 (19,500 ft above the 1013.2 hPa datum in the UK, or with the altimeter set according to the system published by the competent authority in ...
It is owned by the Telluride Regional Airport Authority. At an elevation of 9,078 feet (2767 m) above sea level, [2] it was the highest commercial airport in North America with scheduled passenger flights when Great Lakes Airlines resumed scheduled passenger service in December 2016; however, those flights ceased in March 2018.

El Alto is the world's highest international airport, located at 4,062 metres (13,327 ft) above sea level. The average temperature at the airport is 6 °C (43 °F). Because of the thin high altitude air, most commercial wide-body aircraft such as the Boeing 747 and Airbus A330 cannot
The C919 aircraft made its debut outside China, staging a fly-by at the pre-show of the 2024 Singapore Airshow. [73] Also at the airshow, Comac announced an order from Tibet Airlines for 40 C919s. The high-altitude variant ordered will have a shortened fuselage and strengthened landing gear for short-field performance. [74]
On August 13, 2001, [1] the Helios Prototype piloted remotely by Greg Kendall reached an altitude of 96,863 feet (29,524 m), a world record for sustained horizontal flight by a winged aircraft. [4] The altitude reached was more than 11,000 feet (3,400 m) — or more than 2 miles (3.2 km) — above the previous altitude record for sustained ...
This is a list of large aircraft, including three types: fixed wing, rotary wing, and airships. 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 ]
