The B737-700 is equipped with what type of handsets? (true statement option)

• A. The B737-700 is equipped with single-purpose handsets
• B. The B737-700 has no handsets
• C. The B737-700 uses wireless only handsets
• D. The B737-700 is equipped with dual-purpose handsets

Answer: (D)

The hands of the B737-700 are dual-purpose, meaning a single handset serves multiple communication tasks. This setup lets crew use the same device for interphone calls between the cabin and the flight deck while also handling other related functions, such as alerts or announcements, without needing separate devices. It streamlines operations, reduces equipment clutter, and speeds up communications when crew need to reach each other or make PA-type interactions. The other possibilities would limit functionality (single-purpose), omit needed equipment (no handsets), or rely on a wireless-only system, which doesn’t match the standard wired, multifunction handsets used on this aircraft.
