Chevron, I'm at bit amazed the the ETPS trainee would be so quick to feather on the Viscount since it does have a nice autofeather system; so much so that it was hard to notice a flamed out inner, at least on the simulator I flew for some years.
I once shut down #3 with the LP cock, trimmed out and handed it over in the air to the next crew who flew about unawares for several minutes until they were given a climb and the autofeather #3 light came on
