Under which conditions must the autofeather system be operable?

The autofeather system on the King Air 350 is designed to enhance safety and performance by automatically feathering an engine in the event of an engine failure. Its operability under all flight conditions ensures that pilots can rely on this critical safety feature during takeoff, climb, cruise, and landing phases of flight.

During takeoff and climb, the system can prevent drag from a failed engine, allowing for optimal performance and handling. In the cruise phase, having the autofeather operable ensures a quick and effective response to any sudden engine failure. Furthermore, during landing, the system is essential for maintaining control and reducing the risk of accidents associated with asymmetrical thrust. Therefore, it is essential that the autofeather system be functional throughout every phase of flight, ensuring maximum safety and performance capabilities regardless of the flight condition.
