Select the correct expansion for the acronym EPU.

• A. Emergency Power Unit
• B. Emergency Processing Unit
• C. Electrical Power Unit
• D. Engine Power Unit

Answer: (A)

In this context, the key idea is a dedicated backup power source that activates during a power loss to keep essential systems running. Emergency Power Unit is the standard expansion, because it clearly communicates a unit designed to supply power in emergencies, ensuring critical hydraulics and controls remain operational. The other phrases aren’t used to name this system in practice, as they don’t convey the established concept of a backup power source activated in emergencies. An Emergency Processing Unit, Electrical Power Unit, or Engine Power Unit aren’t the recognized terms for this function.
