What powers the electronics and hydraulics of a small business jet?

Aurora asked:


I am curious what powers the basic electronics and hydraulics of a business jet? Is it a battery? Is the engine somehow powering it? Is there an APU unit and so on…

    Good answer from Coffeebuff. Jet engines have generators (alternators) and accessory pumps, just like your car engine.

    Yes good answer Coffeebuff.

    I’d like to add that on smaller business aircraft the generator that is used to power the aircraft also dubs as the starter. They simply are called starter-generators. Pretty neat if you ask me.

    Most of the small business jets do not incorporate APU’s. Rather they use batterys to start the engine so they don’t require ground power unless they run out of juice in the batteries.
