I've pondered this one alot.
On the way I've been taught, you are essentially going to be sticking it in the mud - i.e. you set up such that you are dependent on engine to make the runway. If the fan stops, you won't make it if you are on final (vs. cutting in from downwind)
The other method I've seen, used in 'non-gliding' aircraft like the T6, Pitts etc, is run it in quite high and close (i.e. curve into the runway rather than fly a linear approach) then zoom it down late... in the T6 it was "500ft over the numbers" !!
So, err, why don't we fly like that generally? i.e. always keep the option to glide it? There's probably good answers (yuck approach to fly generally, much more skilll required, 'non standard' pattern)
