Never heard of it either. We operate with bleeds off for takeoff/landing anyway.
Edit:..
Just came across this as I went through an old groundschool powerpoint slide:
Autofeather occurs when torque on one engine falls below 28%. The autofeather sequence is now initiated. Immediately upon receiving and AUTOFEATHER signal, the good engine uptrims 10% torque.
- Displayed by a green UPTRIM light located to the left of the ECU switch.
-Torque on the good engine increases 10%.
- There is a 3 second delay then the Autofeather Solenoid Opens and Auxilary Feathering Pump runs for 18 seconds.
-The good engine bleed shuts off.
-Autofeather systems disarms.
Certainly this was something I was never aware of and I guess I was asleep during this part of class. Must try it in the sim next time. As I said earlier, we operate with bleeds off for TO/LDG.
