Which option accurately describes the AIP's function?

• A. Act as call ID, Shows lav smoke, Alerts flight attendant of routine or emergency call
• B. Shows lav smoke only
• C. Acts as call ID only
• D. Alerts flight attendant of routine call only

Answer: (A)

The AIP is the central interphone panel that handles crew-to-cabin communications. It acts as call identification, showing who is initiating a call; it displays lavatory smoke indication so the crew knows if a lavatory issue has been detected; and it alerts flight attendants to both routine calls and emergency calls so they can respond promptly. Because it combines these three functions—identifying the source of calls, signaling lavatory smoke, and alerting for routine or emergency calls—the option that includes all of them is the best description. The other choices leave out one or more of these essential functions.
