That's fine for a takeoff minimum but you may(will) find a time when you're landing with minimum fuel on board and have to do a go-around. It happened to me in the Tripacer when I took off with mininum fuel on board and winds 10G15 and was going to fuel at the destination. When I got there the wind was 20G30 and 90 degrees to the runway. I didn't realize the wind was that stong and messed up the first approach and had to do a go-around. Always figure worst case. Sooner or later it WILL happen. Larry Flesner
