## What is FCST?

FCST is a weather forecast for air sports, sailing and the mountains. We run our own models: WRF for all of Europe (5.4 km grid, ECMWF input), mountain wave on a 1.8 km grid over southern Poland, ICON-D2 over the Alps, and the Andes in Chile.

Pick your disciplines – the home screen shows 0–100 scores, the best time window and a short reason.

GLIDING
• Thermals: climb rate, cloud base, cloud cover, thunderstorm risk.
• Ridge lift from a terrain model and wave at several heights.
• Competitions from SoaringSpot: start window, route in AAT areas, conditions on each leg.
• Forecast files for XCSoar.

VFR FLYING
• Weather along the route at your ETA: ceiling, visibility, icing, thunderstorms, wind.
• Vertical cross-section of the route, METAR and TAF of airfields on the way.
• Suggested route around airspace and an OpenAIP airspace map.

IN-FLIGHT MAP
• Your glider or airplane on the forecast map, your track and the airspace at your altitude.
• Cross-section of the next 20 minutes: real terrain, cloud base, freezing level, rain, thermal top.

PARAGLIDING AND PPG
• Launch site scores: wind at launch and every 100 m up to the inversion, gradient, turbulence, thermals.
• Pilot profile adjusts the wind limits. Launch site database built by pilots.

BALLOON AND SKYDIVING
• Balloon: launch windows and predicted flight trajectories.
• Skydiving: wind at exit altitude and near the ground, jump hours for your drop zone.

SAILING
• Wind in knots and Beaufort, gusts, squalls, waves and currents.
• My voyage: weather along the voyage and the best departure time.

SKIING AND HIKING
• Ski resorts and ski tours: snow, weather, avalanche danger.
• My route: trails and weather at the real elevation of the route.

Also:
• 12-day weather forecast for any place and rain radar.
• Notifications of good and dangerous conditions at your places.
• Home screen widgets.
• Offline forecast maps – work without signal.
• "Who's coming" – see who is heading to the airfield or launch site.
• 6 languages: English, Polish, German, Czech, French, Italian.

Free: the weather forecast without limits, today's discipline forecasts and warnings. Premium (yearly subscription, 14 days free): the following days, any place, widgets with scores, alerts and offline maps.

Forecasts are a planning aid, and the in-flight map is not a navigation device. They do not replace official meteorological information, a briefing or your own assessment of the conditions.

Data: WRF (ECMWF), ICON-D2 (DWD), GFS (NOAA), Open-Meteo, Copernicus, OpenAIP, maps © OpenStreetMap.
