In automatic mode, the blowers of the EAPS are controlled by the MCs to provide automatic operation under what KCAS?

The automatic operation of the Engine Air Particle Separator (EAPS) blowers is designed to activate at a specific airspeed to ensure optimal separation of particles from the engine air intake. In this case, the correct airspeed for automatic operation is 70 KCAS.

This setting reflects a design consideration that allows the EAPS to effectively manage airflow and enhance engine performance by removing contaminants without requiring pilot input. By engaging the blowers at this speed, the system ensures that the engine is protected from potential damage due to particles in the air.

Understanding the functionality of the EAPS and its integration with the aircraft's flight systems at predetermined speeds is essential for maintaining efficiency and safety during flight operations.
