Hung Start – Aircraft Engine

Hung start -  In a  gas turbine engine, a Hung  Start condition is a  normal light off (ignition)  but RPM remains at some low value rather than increasing to the normal idle rpm. This is often the result of insufficient power to the engine from the starter. In the event of a hung start, the engine should be shut down.
