Great article with lots of good information. I did note that there was a range of glide ratios depending on airspeed from 9.5 to 12, and was 11 around the glide speed I have been using in my POH based on my own tests. I guess I should go out and repeat some of my testing to see if the results are similar. Anyway, thanks for the link.
