Which color indicates an interphone Crew-To-Crew call including the Captain?

• A. Interphone Crew-To-Crew including Captain
• B. Customer calling from seat
• C. Customer calling from lavatory
• D. Emergency signaling

Answer: (A)

Interphone signals use color coding to tell you who the call is for and how to respond. A Crew-To-Crew call that includes the Captain is an internal communication among the flight crew, so the color associated with that signal is reserved for messages that involve the crew and the Captain. This is why selecting the option that describes a Crew-To-Crew call including the Captain is the best choice—it indicates the internal, Captain-inclusive channel that you should answer on. The other options describe calls from customers or emergencies, which use different signals and priorities, so they aren’t the signal you’d use for crew coordination with the Captain.
