Where are interphones located?

• A. At all minimum crew jumpseats, 3 in OFCR, and 1 in OFAR
• B. In cockpit and cabin only
• C. In overhead panels
• D. In lavatories

Answer: (A)

Interphones are placed where crew need immediate access to communicate with the flight deck and with each other, regardless of where they are in the cabin or crew rest areas. On the 787, there are interphone units at all minimum crew jumpseats, plus additional units in the crew rest areas: three in the forward crew rest and one in the aft crew rest. This arrangement ensures cabin crew and pilots can reach the interphone from any working position, even when resting or distributed in different zones. They’re not limited to cockpit and cabin surfaces, and they aren’t located in lavatories or solely on overhead panels, which is why the described distribution is the correct one.
