Sam, my farm strip is about 450 meters, on the odd occasion I've considered upgrading to a bigger plane I looked at the Saratoga, Cherokee 6 , DArrow, Pathfinder Dakota, C210 and a lot of others, some have book figures that may just make it but those figures are for a plane equipped with a new engine and prop and flown by a factory test pilot. Could they do it? probably, do I want to do it consistently with passengers? probably not the margins are to slim. Sooner or later you're going to have an overshoot.
