Hike & Fly Planer

hikeandfly.org (formerly parange.ch) is a hike & fly planer for Paragliders.

The tool calculates the region a paraglider can reach in theory by gliding from a chosen starting location and elevation. The calculation rests on the assumption of these conditions:

Static air - no wind and no thermals.

- no wind and no thermals. Assumes flying with the set glide ratio even when turning. No change in the glide ration due to braking or accelerating.

even when turning. No change in the glide ration due to braking or accelerating. The height model used is coarse with a grid size of approximately 200 meters. This limitation becomes even more relevant for small glide ratios.

The tool is meant to supplement flight preparations especially for hike & fly type trips in the Alps in addition to things like the weather forecast, aeronautical charts, and common sense.

Coverage

The tool currently covers the earth's land surface except Antarctica, Greenland, Iceland, and a few remote islands. If you are missing coverage for a certain area or if you find some strange results please contact me.

Acknowledgement

The digital elevation model is based on 3 arc second data from Jonathan de Ferranti's View Finder Panoramas-Project.
