Generally the symptoms of an engine flameout are an
uncommanded drop in engine speed and abnormal engine
instrument readings. The flameout may result from a
momentary running out of fuel or may possibly be caused by an
unstable engine operation e.g. due to adverse engine intake
entry conditions. Once fuel supply has been restored or engine
operation has been recovered to stable conditions and after an
engine emergency shut down, the engine may be restarted.
Note A hot restart may be initiated immediately after a flameout
or engine emergency shut down occurred, irrespective of
altitude or speed conditions, provided that the flameout was
not the result of a malfunction (e.g. mechanical failure) that
might make it dangerous to attempt an engine restart.
Caution Except during an emergency, do not attempt an in-flight
engine restart between 1 and 10 minutes after engine failure
Important Safe engine air start is possible up to 24.000 ft pressure
altitude and at airspeed up to 140 kt TAS.
