An engine separation basically means that you physically lost | ✈️Aviation English

An engine separation basically means that you physically lost your engine. This situation is really rare but it's also easy to diagnose as you lose all your engine indications.

E.g.
Loss of control was caused by engine detachment due to improper maintenance.

The right engine separated just after takeoff.

P.S. Watch the video extract in another post and pay attention to the phrase "engine departed"
