Who controls the lighting on the aircraft?

The correct answer indicates that the flight attendants, specifically FA1 and FA2, have control over the lighting in the aircraft. This is because flight attendants are responsible for the cabin environment, which includes managing lights for passenger comfort and safety. They can adjust the lighting according to different phases of the flight, such as during boarding, meal service, or before landing.

This control is crucial for ensuring an optimal atmosphere in the cabin that caters to passenger needs, enhances visibility, or creates the appropriate ambiance during important flight phases.

In contrast, roles such as the captain, flight engineer, or ground control may be primarily focused on the aircraft's operational and navigational systems, rather than the interior ambiance directly affecting passengers.
