What does a decrease in airspeed during propeller overspeed help maintain?

A decrease in airspeed during propeller overspeed is essential for maintaining the optimal RPM of 2700. The phenomenon of propeller overspeed occurs when the engine's rotational speed exceeds the normal operating limits, risking damage to the engine and propeller system. In this scenario, reducing airspeed can help manage the overspeed condition by limiting the amount of thrust generated by the propeller, thus allowing the engine to stabilize at a safer RPM range.

Keeping the propeller within its optimal RPM not only protects the mechanical integrity of the engine and propellers but also ensures steady and predictable performance during flight. When the RPM exceeds the optimal range, the risk of damage increases, making adherence to this target RPM critical for safe operation.
