How is the galley air heated?

• A. By a 1000 watt electric heater, controlled by the HEATER switchlight at the galley control panel.
• B. By a 1500 watt electric heater controlled from the cockpit.
• C. From engine bleed air through a dedicated heat exchanger.
• D. By a small fuel heater in the galley cabinet.

Answer: (A)

Galley air is heated by a self-contained electric heater in the galley, rated at 1000 watts and controlled by the HEATER switchlight on the galley control panel. This setup provides local warmth directly in the galley and lets crew adjust it without involving cockpit controls or the engine bleed air system. The option of a cockpit-controlled 1500-watt heater isn’t consistent with the galley panel control. Using engine bleed air through a dedicated heat exchanger would be part of the aircraft’s main environmental system, not a separate galley heater. A small fuel heater in the galley cabinet would introduce fuel handling and potential fire risk, which isn’t how galley heating is implemented here.
