Which of the following best describes the location of the 60 Hz converter?

• A. On the deck under the pubs library/bookcase (FS 236)
• B. In the avionics bay behind the cockpit
• C. In the forward cabin ceiling panel
• D. In the tail cone area

Answer: (A)

60 Hz converters are part of the aircraft’s electrical system and are placed where they can be serviced easily, stay cool, and efficiently feed the loads that need 60 Hz power. In this configuration, the deck area under the pubs library/bookcase (FS 236) is the designated space for such auxiliary power equipment. That location keeps the converter out of the heat and vibration of the avionics bay behind the cockpit, while still being accessible to maintenance and close enough to cabin circuits that require 60 Hz, minimizing long wiring runs. The other proposed spots are less practical: the avionics bay is a harsh, restricted area for a nonessential converter; the forward cabin ceiling panel isn’t a serviceable equipment bay; and the tail cone area is inaccessible and distant from the cabin systems that would use the power.
