If you Dive n Drive, with approach flap and a minimum of, say 400', then you are not stable by 500' (no land flap) so you must go around.
You could be up there all day!
Flying a level segment in a med/lge transport aircrafdt is barking mad. Even more so on one engine!
Notional glidepath and add 50' or so to the MDA and use it as a DA.
If you can't get in from that, go somewhere else!
