What aspect of cabin functionality can the FAP control?

The cabin functionality that the FAP, or Flight Attendant Panel, can control is cabin lighting. The FAP is specifically designed to allow flight attendants to manage various aspects of the cabin environment, and one of its primary features is the ability to adjust lighting. This includes controlling overhead lights, reading lights, and other ambient lighting in the passenger cabin.

While the other options related to passenger seat adjustments, overhead storage, and galley equipment may be part of the cabin experience, they do not fall under the direct control of the FAP. Seat adjustments are typically managed by individual passengers or via controls specific to the seat. Overhead storage is a fixed feature of the aircraft and does not require active control. Galley equipment is managed by the crew in different operational ways, focusing on services and food preparation rather than through the FAP. Therefore, cabin lighting is the most accurate representation of the control capabilities associated with the FAP.
