When we go to recurrent for the SA227 Metroliner, most of our recurrent is focused on V1 cuts. The Metro doesn't have an auto-feather system per se. It has a Negative Torque Sensing (NTS) system. This system, hopefully properly working, senses if the engine is turning the prop or the prop is turning the engine. If the system NTSes, then it will slowly let oil out of the prop hub and move the prop to a feathered position. If the NTS system does not feather the prop then you have an 8' diameter prop disk out there trying to put you into the ground! After setting max power, rotating, and getting the gear up, you have to immediately manually feather the prop. If you don't you will run out of aileron and rudder authority and make a smoking a hole in the ground.
