Does this aircraft have an APU SERV BUS button on the FA panel on the CRJ 700?

• A. Yes
• B. No
• C. Only on some variants
• D. Not labeled as such

Answer: (B)

APU and service bus control are cockpit items, not cabin cabin-panel items. On the CRJ 700, the Flight Attendant (FA) panel is used for cabin operations (calling, interphone, lights, galley/lav utilities, etc.), while the APU and electrical bus controls live in the flight deck overhead/electrical panels. Since there isn’t a dedicated APU SERV BUS control on the FA panel, the button isn’t present there. If you need to manage the APU or service bus, that’s done from the cockpit, not the cabin panel.
