Re: Glide Ratio

I see your autocorrect keeps wanting to make "ratio" into "ration". Mine does too!
I need to go fly this again and get a bigger data set and plot this again. It is distinctly different than when I measured in summer temperatures but with the aircraft at the SAME load condition and Density Altitude AGL.
Because there is Vg and there is VMinSink (which the glider guys use to loiter while looking for lift). They are usually different and that quick dataset from today doesn't show it. On these short stubby wings they may well be almost the same - I know when I did it extensively with my 150 there was only about a 1 knot difference - which was way within the margin of pilot error.
I've shot a note to a mathematician/aerodynamicist to try and glean why I got different answers at the same DA but different temperatures.

Any Onex owners or glider pilots who know the answer about different Vg for different seasons but same DA?
