Auto feathering is disarmed
- during landing.
- during take off.
- in the cruise.
Explanation
Autofeather is needed during the high-thrust phases of take-off and the initial climb to feather a failed engine quickly; once safely in the cruise it is no longer required and is disarmed to prevent an unwanted feather. It is therefore armed for take-off, not disarmed then.
Jordi asking:
why is it disarmed during cruise?Wouldnt be right to have it auto while crusing in case of engine failure?

I've searched it on the internet and it says: "An automatic feathering system was first introduced on the Martin 4-0-4 aircraft, a piston engine airplane. The system was designed to automatically feather an engine that failed during takeoff or initial climb. It is not used during cruise.".
