Paul,

Actually I entered the data in your conversion spreadsheet as a
Cambridge Polar File and then posted the resulting See You data
points.

Using the best L/D and speed and the 2 meter sink rate at speed, when
I checked the resulting generated polar, it was pretty close to the
Johnson measured polar. Close enough that I would fly with it.

Best L/D was actually measured at 36.8 @ 92 kph and the 2 meter sink
speed @ 148kph. Test weight was 315.2 kg.

Hi Mike,

Those numbers look like they may be correct. *Hopefully, when you enter
those numbers into SeeYou Mobile, it displays the correct glide ratio and
other data.

If you send me the 3 airspeed and sink rate pairs (with the lowest speed one
at the best L/D speed). *I would be glad to put them onto my Polars web
site. *I will also need to know the wing loading at which the numbers were
obtained.

Best Regards,

Paul Remde

Mike,
I do not understand what to enter on the SeeYou Mobile
Polar setting page. There are six available boxes.
Name Sgs 1-35
Min Load - 6.38
Stall Speed - 43 mph
a -
b -
c -

I do not know what goes in a, b, c boxes.
Even when I look at the polars for my own
glider, I do not understand what the numbers
mean.

If I entered the data correctly into Paul's spreadsheet, and the
conversion from a cambridge file to a See you *file is correct, the
data supplied by Dick Johnson's actual test polar at his weight is ...

a= 2.1
b= -4.4
c= 3.2
