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]
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.
Aerobatic maneuvers are flight paths putting aircraft in unusual attitudes, in air shows, dogfights or competition aerobatics. Aerobatics can be performed by a single aircraft or in formation with several others. Nearly all aircraft are capable of performing aerobatics maneuvers of some kind, although it may not be legal or safe to do so in ...
The Maneuvering Characteristics Augmentation System (MCAS) is a flight stabilizing feature developed by Boeing that became notorious for its role in two fatal accidents of the 737 MAX in 2018 and 2019, which killed all 346 passengers and crew among both flights.
In aircraft with high-mounted tailplanes, like the F-101 Voodoo, recovery was especially difficult because the tailplane was placed directly in the wing wake during the pitch-up, causing deep stall (although the T-tail was meant to prevent pitch-up from starting in the first place). Deployment of the braking parachute and a considerable height ...
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.
The required altitude depends on the type of terrain, such as low vegetation or low buildings, tree canopy layer of less than 45 m (148 ft), presence of tall buildings or concrete pylons with heights of up to 25 m (82 ft) international standard, or emergent tree layer canopy and lattice steel electricity pylons to 100 m (330 ft) being present ...
