What Pilots Say

"XC Therm really is a huge enrichment for me. Everything you need, but not too complicated. The perfect tool for planning the week - when and where to fly."

Patrick von Känel

3x X-Alps Finisher, Swiss XC Champion

"I consider XC Therm currently the most useful forecast for evaluating the flight potential. Because the app works reliably, I am even more confident that I will be at the right place at the right time during the next X-Alps!"

Chrigel Maurer

8x X-Alps Champion, 3x World Champion

"For a long time I have been looking for a possibility to have a detailed and precise but yet compact and affordable thermal and flight weather forecast over several days on my mobile devices. XC Therm fulfills all these requirements."

Thermal Overview

The thermal overview shows the potential flight distance for each of the subscribed regions on the interactive map for 5 consecutive days starting from the current day.

The potential flight distance (PFD) of a region is calculated with the help of these parameters:
