What might occur if the RPM falls within the prohibited range?

When the RPM falls within the prohibited range, it can lead to potential engine damage. This is because operating within this range may cause excessive stress on the engine components and disrupt the normal operation of the engine systems. An RPM that is too low or too high can result in adverse conditions such as vibrations, overheating, or even mechanical failure. Engines are designed to operate optimally within specified RPM limits, and exceeding or dropping below these limits can lead to diminished performance and serious damage, necessitating costly repairs or overhauls.

Understanding the implications of RPM operation is crucial for maintaining the health of the engine and ensuring safe flight operations. Recognizing the RPM limits and adhering to them helps prevent incidents that could compromise aircraft safety.
