Hi CanadianSim

Welcome to the Captain Sim forums.

As far as I know. The Galley Power provides power to the Galley, so the Flight Attendants have power for the ovens, urns/kettles and fridges so they can provide hot or cold drinks and hot food. In the 707, the switch is there and can be turned ON or OFF, but other than simulating power use, it doesn't really do anything at all.

I'm happy to be corrected if I am wrong.
