Which cockpit switch enables AC power to cabin outlets?

In aircraft systems, the switch that specifically enables AC power to cabin outlets is designed to control the flow of electrical energy to those specific outlets used for passenger convenience and operation of cabin equipment. The FURN switch is often associated with the controls for heating and cooling systems within the cabin, which typically require AC power to function properly.

This switch is dedicated to facilitating cabin comfort systems, ensuring that electrical appliances can operate effectively during flight. It regulates power to outlets where passengers might plug in devices, thus directly linking it to the availability of AC power in the cabin.

Other switches, such as the AC Power switch, may manage the overall distribution of AC power within the aircraft, but they do not specifically indicate the connection to cabin outlets. The Cabin Power switch, similarly, might be a more generalized control without the specific intent of allowing power solely to cabin outlets. The Battery switch governs the power from the aircraft's battery, which is not directly related to power directed at cabin outlets.

In summary, the FURN switch stands out as the decision point that specifically connects AC power to cabin outlets, making it essential for ensuring that necessary systems remain operational within the passenger area.
