Ground running for engine testing without flight will accumulate time.

Ground running for engine testing without flight will accumulate time.

• A. Sometimes
• B. Not Specified
• C. True
• D. False

Answer: (C)

Time on an engine is accumulated whenever the engine is running, regardless of flight status. During a ground test, the engine is actively rotating, with oil flow, fuel combustion, heat generation, and mechanical wear occurring just as in flight. The engine’s hour meter tracks this running time, so ground runs contribute to the total engine hours used for maintenance planning and overhaul schedules. Therefore, ground running for testing without flight will accumulate time.
