Which statement about interphone preflight is true?

• A. Both FAs must preflight each interphone
• B. Only one FA preflights
• C. Interphones do not require preflight
• D. Maintenance preflights interphones

Answer: (A)

Intercoms are a two-way link between the cabin crew and the flight deck, and reliable communication is critical for safety and coordination. The best practice is that both flight attendants perform the preflight check on their interphone stations. By doing so, each FA verifies that their own handset, microphone, and speaker work, and also confirms that calls can be placed to and answered by the flight deck and that the flight deck can reach them back. This bidirectional test from both ends catches faults that a single check might miss, such as a microphone on one side being dead or a speaker on the other side being out of range, ensuring there’s a dependable path for communication in normal operations and in an emergency. If only one crew member tested the interphone, a fault on the other station or on the flight deck side could go undetected, leaving a potential communication failure unaddressed when it’s most needed. Interphones do require preflight, and maintenance isn’t typically performing the cabin crew’s preflight during passenger service.
