What Pilots Say

Patrick von Känel

"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
Christian Maurer

"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
Uli Strasser

"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 Map

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 of a region is calculated with the help of these parameters:

  • Wind and climb values for that region
  • Aircraft (paraglider, hang glider, rigid wing)
  • Pilot skills (configurable)

The detailed forcast is displayed by tapping or clicking on that region.

Detailed Forecast

The detailed forecast for a region is available both as a chart and a text representation. In a 30-minute interval it informs about:

  • Expected climb rates
  • Cumulus clouds
  • Cloud cover (low, medium, high)
  • Wind at optimal flight level
  • Weather warnings (thunderstorms, rain, etc.)*

* currently only available in text representation
