Final answer:
The pilot's rapid changes of throttle, propeller RPM control, or mixture control can have a significant impact on the aircraft's performance.
Step-by-step explanation:
The statement is true.
If the pilot makes rapid changes of throttle, propeller RPM control, or mixture control, it can result in rapid changes in engine power output, propeller efficiency, and fuel-air mixture. For example, rapid changes in throttle can lead to quick adjustments in the amount of fuel-air mixture being supplied to the engine, which can in turn affect the power output and performance of the aircraft.
Therefore, rapid changes in throttle, propeller RPM control, or mixture control can have a significant impact on the aircraft's performance and should be done carefully and in accordance with the aircraft's operating procedures.
