i m just looking for material that is approved by the relevant authority and allows the crew to manually feather before reaching the acceleration altitude in case auto fx fails.
sweet discussion gents, but in the very rare event that a turboprop gets in real life at hot and high conditions with max takeoff mass an engine failure exactly at rotation AND autofeather fails simultany you are pretty close to crash before you have time to think what and why happened.
its not the question of the authority, its the question of emergency procedures for the type and common sense of the crew. all single engine operation procedures and performance numbers are regarded to a feathered prop -so the answer should be obvious what to do when decision is made to survive such a scenario.
without any doubt one memory item should be to change underwear after landing , i quess you will not find this in the checklist .
