What color is the solid indicator seen during a normal call from the Flight Deck?

• A. Red
• B. Green
• C. Amber
• D. Blue

Answer: (A)

A solid red indicator is used to show an active Flight Deck to cabin call. When the flight deck initiates communication, the red light stays solid to give a clear, immediate cue that a call is in progress and needs attention. This color-coding helps crew respond quickly without relying on audio cues alone. Other colors are used for different signaling functions, so they wouldn’t represent a normal Flight Deck call.
