Hello all,

This is a really stupid question and I don't know how I don't know the answer but, what's APU and what does it do? I see APU Gen and APU start stuff and I think 😳

Thanks in advance,

APU = Auxilliary Power Unit - a small gas turbine which powers a separate generator.

Normally engine powered generators will provide electrical power, but if a generator fails (etc), the APU can be used to provide power and "replace" a failed generator.
