cruise vs. climb article location
I am looking for an article from several years ago that discussed the
relative importance of climb rate as compared to speed to fly between thermals. This was a fairly detailed comparison of percentage impact on net speed, emphasizing that 5-10mph cruise errors was far less important than selection and optimal use of best thermals. If anyone remembers where this article is , I would appreciate your helping me find it. Thanks, SZ

cruise vs. climb article location
Just calculating the cruise speed in Excel will help as well with the
help of the polar. This shows that flying 10% faster or slower will decrease max cruise (with a modern 15-meter class glider) with less than a percent disadvantage...

I second Shawn! John Cochrane's "Just a little faster please" article is
well written, condensed and excellent information PeterK http://www.xs4all.nl/~arjanvd/flyingfaster.pdf "Shawn" wrote in message . ..

Little Faster, Please" located at http://faculty.chicagogsb.edu/john.c...ers/#maccready "Frank Whiteley" wrote in message ups.com...
