What is defined as a back-up power source that provides power to radio installations for distress and safety when the vessel's main and emergency generators cannot?

• A. Auxiliary Generator
• B. Reserve Source of Energy
• C. Battery Bank
• D. Solar Array

Answer: (B)

The concept being tested is ensuring that critical radio equipment keeps running when the ship loses power. The best answer is Reserve Source of Energy. This term refers to a dedicated backup power source that automatically powers the vessel’s radio installations for distress and safety if the main and emergency generators are unavailable. It is typically provided by a battery-based energy storage system sized specifically to support the radio gear during power outages, independent of the ship’s primary generators. While a battery bank is a common component of such a reserve, the formal designation used in regulations and practice is Reserve Source of Energy. An auxiliary generator is another power option but not the defined backup energy source for radio gear in this context, and a solar array is not the standard means for maintaining essential distress communications.
