What color illuminates on the flight attendant indicator panel for a call from a passenger in their seat?

The flight attendant indicator panel uses the color blue to signal a call from a passenger in their seat. This designation is standard across many aircraft to ensure clarity and quick recognition by flight attendants. The blue light indicates that the flight attendant needs to respond to a passenger request, distinguishing it from other situations or alerts that may require attention.

In typical scenarios, red lights usually indicate more urgent situations, such as emergency calls, while white and green are used for different purposes within the aircraft systems or for other types of passenger communication. The consistent use of blue for passenger calls enhances situational awareness for the cabin crew and aids in timely responses to passengers’ needs during the flight.
