What is Autofeather?
'''Autofeather''' is a feature of the engines on [[turboprop]] or piston engine [[aircraft]]. When the power being made by the [[Aircraft engine|engine]] falls to the point where it is not helping add to the thrust, the [[propeller]] will go into a [[Feathering (disambiguation)|feathered]] mode to help lower the amount of [[Drag (physics)|drag]]. An automatic feathering system was first brought out into the open on the [[Martin 4-0-4]] aircraft, which was a piston engine airplane. The system was made to automatically feather an engine that failed during takeoff or the initial climb of the plane to its cruising [[altitude]]. {{Transport-stub}} [[Category:Aircraft engines]]
