The Speed to fly functionality of the ClearNav vario works pretty well for giving you a speed to fly number based on the current conditions. I don't constantly chase the number it displays, but it is a good number to work off of.



Somehow, suggesting a ClearNav (or even XCSoar) to someone who is talking about making paper speed rings for club gliders doesn't seem reasonable, but I guess I'm behind the times.

For the original poster, Paul Remde has an good assortment of soaring related spreadsheets he

In particular, polar6th.xls does pretty much what you want. There is also this web app:

Agreed, I believe the OP stated this was for club ships and/or "just hopping in for a flight". Thus, may not have access to much more than basic instruments in these cases.

As I remind my 2 teenagers (which I supply cellphones for....), not everyone has a "smartphone", thus some of the apps & programs people mention have no relevance to me.
Glad they help out others though.
