The U.S. NASA Aviation Safety Program [2] [3] defines upset prevention and upset recovery as to prevent loss-of-control accidents due to aircraft upset after inadvertently entering an extreme or abnormal flight attitude. A Boeing-compiled list determined that 2,051 people died in 22 accidents in the years 1998–2007 due to LOC accidents. [1]
One mnemonic for upset recovery is "UPRT": Upset; Push; Roll; Thrust; On noticing an unusual flight condition, the pilot should first reduce the thrust, and push forward on the yoke to unstall the aircraft. An aircraft cannot be stalled at zero g. [8] The pilot should then roll the shortest way to the horizon. Finally thrust can be increased ...
China Airlines Flight 006 (call sign "Dynasty 006") was a daily non-stop flight from Taipei to Los Angeles International Airport. On February 19, 1985, the Boeing 747SP operating the flight was involved in an aircraft upset accident , following the failure of the No. 4 engine, while cruising at 41,000 ft (12,500 m).
A Delta plane flies by the wreckage of Delta Flight 191 the day after the Aug. 2, 1985, crash. JOE GIRON/Star-Telegram There have been 2,751 aircraft crashes with a fatality in Texas in more than ...
Generally, though, spin training is undertaken in an "Unusual attitude recovery course" or as a part of an aerobatics endorsement (though not all countries actually require training for aerobatics). However, understanding and being able to recover from spins is certainly a skill that a fixed-wing pilot could learn for safety.
APS is known for their approach to UPRT that includes the combination of computer-based, on-aircraft, and full-flight simulator training platforms, which reduce the risk of Loss of Control In-flight (LOC-I) through flight training. [13] Their live on-aircraft training platforms include the Marchetti S211 piston Extra 300L. [14]
The mass exodus from Cuba took an unusual twist Friday, when a pilot in a Soviet-era biplane took off from the island just 90 miles south of Key West and landed on an isolated, mostly forgotten ...
Throughout a normal flight, a pilot controls an aircraft through the use of flight controls including maintaining straight and level flight, as well as turns, climbing, and descending. Some controls, such as a "yoke" or "stick" move and adjust the control surfaces which affects the aircraft's attitude in the three axes of pitch, roll, and yaw.
