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.
Three right-handed, Cartesian coordinate systems see frequent use in flight dynamics. The first coordinate system has an origin fixed in the reference frame of the Earth: Earth frame Origin - arbitrary, fixed relative to the surface of the Earth; x E axis - positive in the direction of north; y E axis - positive in the direction of east
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
NATO tactical ultra-low-level flight training in Canada is located at CFB Goose Bay in Labrador.In response to lessons learned from the Vietnam War and the growing sophistication of Soviet anti-aircraft radar and surface-to-air missile technology being deployed in Europe, NATO allies began looking at new doctrines in the 1970s–1980s which mandated low-level flight to evade detection.
The Automatic Ground Collision Avoidance System (Auto-GCAS) enhances safety by mitigating controlled flight into terrain (CFIT) accidents. [1] The Auto-GCAS team was awarded the 2018 Collier Trophy for the design-integration and flight testing in the F-35 , marking the year's greatest achievement in aeronautics. [ 2 ]
The grounding order was fully lifted, along with all restrictions on flight ceiling and student pilots, in August 2017. [32] The T-45 fleet was thereafter upgraded with new sensors to monitor the onboard oxygen systems, as well as a new water separation system, in hopes of reducing hypoxia events and determining the root cause of the problems.
