How does an RPM gauge function in aircraft engines?

• A. It indicates fuel flow rate
• B. It measures static pressure in the engine
• C. It measures the engine's rotational speed
• D. It calculates the engine temperature

Answer: (C)

The RPM gauge, or revolutions per minute gauge, functions by measuring the engine's rotational speed. This critical instrument provides real-time feedback on how quickly the engine is rotating, which is essential for monitoring performance and ensuring efficient operation. The measurement is typically taken from a sensor connected to the engine's crankshaft or turbine, translating the rotational speed into a readable format on the gauge. Understanding the RPM helps pilots and maintenance technicians identify optimal operating ranges and detect potential issues with the engine’s performance or health. This makes it a vital tool in the overall management and safety of aircraft operations.
