The field has chosen me four times, and happily, each time, I was able to fly it out when the problem was resolved. Two were EFATO's. The 12 to 1 for a power plane is optimistic, as some glide half that well. As Piperboy has well reminded us, practice!
John Farley has written that you pick the more near field, and make it, rather than pick the far one, and hope to make it. My personal preference would be to overshoot because of my mis judgement, rather that to undershoot. If I got it wrong, I'd rather go between two trees at the far end, at 10 MPH, than hit the embankment on the approach end at 60 MPH!
Routine rental flying does not lend itself to practicing forced approaches, particularly on the one or two flights a month, with the wife or kids, but you've got to practice....
