Which flight attendant will preflight each of the interphones?

• A. Both
• B. Lead FA Only
• C. Aft FA Only
• D. None

Answer: (A)

Interphone preflight checks must be done for each unit in its own area to ensure reliable crew communication throughout the flight. With two interphone units in the aircraft—one forward and one aft—each is tested by the FA responsible for that section. The forward interphone is checked by the forward (lead) FA so they can talk to the flight deck and the cabin, while the aft interphone is checked by the aft FA to ensure rear cabin calls and crew coordination work properly. By having both FAs perform their respective checks, you guarantee that no communication link is left unverified before pushback. If only one unit were checked, a failure in the other could isolate a crew member from essential calls, which is why the correct approach is to preflight both.
