Which system is monitored by the Battery Feeder Protection Unit for short circuits?

• A. Navigation Systems
• B. Communication Systems
• C. Battery and external power lines
• D. Fuel System

Answer: (C)

The Battery Feeder Protection Unit is designed to protect the aircraft's electrical systems, particularly by monitoring the battery and external power lines. This unit plays a crucial role in detecting short circuits that could occur within these power distribution lines. By continuously monitoring the electrical integrity of the battery feeder and external power sources, it ensures that any abnormal conditions, such as a short circuit, are identified promptly. This protection is vital for maintaining the safety and operational reliability of the aircraft, as any fault in the battery or external power lines could lead to significant issues, such as loss of power to critical systems or even fire hazards. The other options relate to various aircraft systems, but they are not directly monitored by the Battery Feeder Protection Unit for short-circuit conditions, hence why they do not represent the correct focus of this unit’s function.
