What RPM does EPECS set the propeller RPM to for normal operation in flight?

Explanation:
In normal flight, the propeller is kept at a fixed cruise speed by the electronic propeller control system. That system targets 1700 RPM because it provides an efficient balance of thrust, fuel economy, and engine load across a wide range of altitudes and air speeds. It achieves this by automatically adjusting the blade pitch to hold the RPM steady whenever you’re in normal cruise. Higher RPM settings are reserved for high-power phases like takeoff or climbs, while lower RPM settings would reduce thrust too much for typical cruise. So 1700 RPM is the standard cruise setting the system maintains in normal operation.
