Which system is powered by the Secondary 115V AC Bus?

• A. Ground Recording Equipment
• B. Landing Lights
• C. Communication System
• D. Engine Monitoring Equipment

Answer: (A)

The Secondary 115V AC Bus powers essential systems onboard the aircraft, with one of its primary functions being to supply electricity to Ground Recording Equipment. This equipment is crucial for maintaining operational records and monitoring the condition of the aircraft while it is on the ground. The Ground Recording Equipment requires a stable power source to function correctly, which is provided through the Secondary 115V AC Bus. This bus helps ensure that important data logging and maintenance systems remain operational even when other power sources are not available. In contrast, other systems like landing lights, communication systems, and engine monitoring equipment often rely on different power buses or systems specifically designed to meet their power needs. The distinction in power sourcing is important for understanding how different aircraft systems are prioritized and managed.
