Line pull Excel spreadsheet
« on: June 03, 2009, 06:22:21 PM »
I've written a small Excel sheet to calculate line pull at different heights above ground. I just found that I can't post it, so e-mail me if you'd like a copy.

I'd be interested to get your feedback and additions or corrections.

The calculated pull feels about right for my Panther.

Humm, have you tried copy and paste into your message or do you have it set up for feeding in parameters and getting line pull calculated? If the latter, you may well be blocked from posting here.

Out of curiosity, do you assume the same laptime, or same airspeed??

You need to run it in Excel, so cut and paste won't work, though I could post a screenshot, I suppose.

I assume a constant air speed, calculated from the laptime.  User enters lap time, circle radius (line length + arm + distance to A/C center) and airplane weight.
