aviation term for a corkscrew downward path

gas turbine phenomenon

inability of a person to correctly determine their body position in space

turbulence caused by difference in air pressure on either side of wing

aircraft or spacecraft landing which causes substantial damage to the vehicle

aircraft damage attributed to a foreign object

Aerodynamic condition related to helicopter flight

In aviation, a flameout (or flame-out) is the run-down of a jet engine or other turbine engine due to the extinguishment of the flame in its combustor. The loss of flame can have a variety of causes, such as fuel starvation, excessive altitude, compressor stall, foreign object damage deriving from birds, hail, or volcanic ash, severe precipitation, mechanical failure, or very low ambient temperatures.

decision, action or inaction by a pilot of an aircraft

imbalance helicopter rotation when the blades become bunched in the rotational plane, typically on the ground when the landing gear is prevented from freely moving

torus-shaped vortex in a fluid or gas

in-flight visual impairment by pilots

aviation incident in which an unauthorized object enters an active runway

turbine engine unexpectedly stops producing power due to a malfunction other than fuel exhaustion

expert group providing information on atmospheric volcanic ash clouds hazardous for airplanes

aviation incident in which the aircraft suffers damage from leaving the runway

Liability and equipment coverage for aircraft

Abrupt change in an aircraft's roll due to fuselage inertia

misjudgment of true orientation by pilots

Term in rotorcraft aerodynamics

human machine interface extension of an aircraft's control system that prevents the pilot of an aircraft from making control commands that would force the aircraft to exceed its structural and aerodynamic operating limits

phenomenon of rapid air movement produced by the jet engines of aircraft
