Sea King Self Starting?
Having been parked in a hospital car park for over 45 minutes near a Sea King helicopter with either an engine or APU running, a friend asked me if Sea Kings were self starting from scratch without a ground power unit.
As an aeroplane driver I can think of several reasons why you might sit for 45 minutes with the engine or APU running, and it seems unlikely to me that an aircraft capable of landing "off piste" wouldn't be self sufficient, but I don't actually know the answer!
TIA if anyone can enlighten me.
