Beagle's post re the STUPRECC drill in the Gnat (had to Google it!) has raised some interesting points in my mind. Essentially a PEFATO is NOT an EFATO, and could actually lead a pilot into believing turning back after the engine quits is a good idea, when it really isn't. Firstly, with the engine idling all the systems still work and secondly, at flight idle the engine must be producing some thrust. Not a lot, but possibly just enough to be the difference between a hard landing in the undershoot and a ball of flame in the approach lights. All IMHO of course.
