At 8000 feet, what is the range of the tachometer for the Cessna 152?

The correct range for the tachometer on the Cessna 152 at 8000 feet is indeed 1900-2550 RPM. This range is crucial for pilots as it indicates the optimal operating speed of the engine at that altitude, ensuring it operates efficiently and safely.

As altitude increases, engine performance can be affected due to the reduced air density, which can alter the engine's power output and operating characteristics. The specified RPM range is designed to maximize performance while preventing engine over-revving or undue strain.

Understanding this range assists pilots in maintaining proper engine operation and performance during flight, especially during critical phases such as takeoff and climb where engine performance can be vital for safety.
