Sailplane polar comparison software

[Mr David Donald]

Some years ago, I was able to download an excel spreadsheet that
compared two gliders (via drop down boxes). It displayed their polars
in different colours against each other. It also showed their sink
rates at speed.

My computer has crashed and I'm trying to find a copy. Anyone got
one out there?

Dave.

Hi Dave,

It is from Australia. I have a link to it on my Soaring-Links Theory,
Equations & Spreadsheets page here:

Thanks Paul. I haven't seen anything like it, but the aircraft are now getting a
bit dated. I wonder if anyone has a version where any additional data has been
added.

While the aircraft may be dated, they are still capable of carrying me further
than I could fly them!!

Regards,

Dave.
