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 ...
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]
The U.S. FAA lists factors of aircraft upset in the Airplane Upset Recovery Training Aid [1] [2] as follows: Turbulence causes: Clear air turbulence; Mountain wave turbulence; Windshear; Thunderstorms; Microbursts; Wake turbulence; Aircraft icing; Systems anomalies: Flight instruments; Autoflight systems; Flight control and other anomalies ...
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.
The nose attitude was not in a sufficient upwards position for a recovery as it was only put at 8 degree and the aircraft's landing gear was not retracted. Due to the low altitude of the aircraft, according to investigators the crew would've needed a much more higher setting of the thrust lever (at fully forward position) and the landing gear ...
A final approach over a downsloping terrain with a flat runway, or to an unusually wide runway may produce the visual illusion of being too low on final approach. The pilot may then pitch the aircraft's nose up to increase the altitude, which can result in a low-altitude stall or a missed approach. [13]: 2, 3
A Delta Airlines flight had to return minutes after takeoff as passengers’ noses began bleeding when the cabin failed to pressurize as it climbed high into the air.. The Boeing 737-900 plane ...
For aviators, proper recognition of aircraft attitude is most critical at night or in poor weather, when there is no visible horizon; in these conditions, aviators may determine aircraft attitude by reference to an attitude indicator. Spatial disorientation can occur in other situations where visibility is reduced, such as diving operations.
