What does the AIP do?

• A. Acts as a caller ID for inter-phone
• B. Shows which lavatory smoke detector has been activated
• C. Alerts FA's of routine and emergency calls
• D. All of the above

Answer: (D)

The Aircraft Interphone Panel is the cabin crew’s main interface for communications and status signals. It handles calls between cabin stations and the flight deck, and it identifies where a call is coming from, acting like a caller ID for interphone communications. It also monitors lavatories for smoke; when a lavatory detector is activated, the AIP lights the corresponding indicator so crew know exactly which lavatory needs attention. In addition, the AIP alerts flight attendants to both routine and emergency calls, using audible and visual cues so responses can be timely and appropriate. Because it covers all these functions, it does all of the above.
