Sub-idle
A question for the powerplant experts. Can you explain the sub-idle condition for a jet engine that is not governed by a fadec? The engine is still running in flight but a section of it is below ground idle and this is causing the accesory gearbox to revolve slowly enough for items to trip off. .
Would advancing the thrust lever lead to an engine stalll or failureif there was a reduced fuel flow which is causing the sub-idle condition?
