Where is the 60 Hz converter located?

• A. On the deck under the pubs library/bookcase (FS 236)
• B. In the nose wheel well
• C. In the cockpit overhead panel
• D. In the aft fuselage area

Answer: (A)

The ability to service and protect an auxiliary 60 Hz converter drives where it is located. This converter is part of the nonessential, cabin-area electrical system, so it’s placed in a maintenance-accessible equipment bay rather than in the cockpit or near moving gear. The deck area under the pubs library/bookcase (FS 236) provides a protected, accessible space for such a unit, keeping it away from the flight-critical systems while minimizing long cable runs to the loads it powers.

Placing it in the nose wheel well would expose it to harsh environment and debris, and near the cockpit overhead panel would clutter the flight deck and expose the unit to cockpit vibrations. The aft fuselage area is farther from where these loads are typically routed and would complicate wiring and cooling.
