Take a Dash 8, fail an engine, fail the autofeather system so that it doesn't feather, handle it ok and it climbs. It's not pretty and the performance is very marginal, but it can be done.
AerocatS2A, thanks for your post.
Are you saying you can get steady-state climb? That is, climb with a constant airspeed?
Or, is the climb of only a short duration (a few seconds - as the airspeed drops off)?
And, there is definitely no NTS action on the prop?
