A flameout refers to the failure of a jet engine caused by the extinction of the flame in the combustion chamber. It can be caused by a number of factors, including fuel exhaustion; compressor stall; insufficient oxygen supply; engine ingestion of foreign substances (such as birds, hail or even volcanic ash); severe inclement weather; mechanical failure; and other factors.
