Hi I was wondering if anyone had any good ideas on how to calculate
short field operations for takeoff on hot summer days.

2400 foot runway, with a supercub at 95 degrees for a single place
glider seems like it would work fine. Your pucker factor does get to
you as you cross the trees at 30-40 feet doing 55 knots.

Of course there's the obvious things that help such as:

-Freshly mowed runway
-1/4 tank of gas in the towplane
-Use a 150 foot rope
-Take off with 10 degrees of flaps on the towplane
-Don't leave any feet behind the glider when setting up at the
beginning of the runway.

If anyone has any other techniques that would help improve safety that
would be great.

Also, if anyone has calculations for this I would appreciate that
too. The POH for all aircraft have short field graphs where you can
use your weight, temp, wind and bada-bing you've got a definitive
answer for just how much runway you need. With a glider behind the
towplane, there aren't any numbers, that I have ever heard of. Unless
anyone here has some personal stories of using a supercub off a short
strip in the middle of summer???

Thanks,
Scott
