Whilst we never say never,
I would always land ahead. Genghis, there have been a number of fatalities in the States, where individuals have attempted a turn back. In my type, Beech Bonanza, a number of studies have been undertaken, (weather dependent), and it seems at least 1200 feet is necessary to even attempt the procedure.
In a twin, land ahead. Always.
The issue is that the aircraft turns into a glider, without the characteristics of one, and you are only going down
My view is that the insurance company can replace the aeroplane, a bit harder to replace the crew and passengers. I also think that the only reason one would turnback was to save the hull. Not worth it in my view.
