Here's an easy approximation... 40:1 glider

Lay your hand on the sectional.

Measure the distance with your finger width.

Each finger width = 1000' of altitude required -- ie, 3 fingers = 3000'
required

(Obvious caveats such as glider performance, width of fingers, etc.)

Ok, so this has sparked a curiosity for me. Who has a list of WAGs
(Mental math calculations) that can be used in the cockpit for glide
distances with wind and such? Is there a resource right now listing
them? Obviously I know it depends on glider performance, but what are
some starting points?
