What is the defined range for continuous engine operation at normal conditions?

The defined range for continuous engine operation at normal conditions for the King Air 350 is set between 94% and 100% RPM. This range is crucial for ensuring that the engines operate efficiently and reliably during prolonged use. Operating within this range helps to maintain engine health, optimize fuel consumption, and avoid undue wear and tear that could lead to mechanical issues.

Exceeding the upper limit of this range risks overheating and excessive stress on the engine components, while operating below this threshold may not provide sufficient power for optimal performance in flight. This balance is essential for safe and successful operation of the aircraft, especially during critical phases such as takeoff and climb, where maintaining proper engine performance is vital.

Thus, having the continuous engine operation range defined as 94-100% RPM reflects the engine manufacturer's guidelines to ensure safety and efficiency.
