If I see a massive runway I couldn't care less what it's called, where it is, or even if it's open, or indeed complete. If it all goes quiet I'm landing there and you can sod your nearest airport button because that doesn't always list ALL runways.
Indeed, look at the Gimli Glider. Never underestimate local knowledge - North Weald isn't on any of our FMS out of STansted by I know if we had a double engine failure off 22 where i'd like to be heading - 1920m unlicensed, but you'd easily do it
