Aufwind: (noun, German) an upward current of air, updraft. A good preparation is crucial for a safe, relaxed, fun, successful cross-country flight. Overlay all relevant information like airspaces, NOTAMs, waypoints and weather on the map and plan your task for the day with the easy to use visual task planner. Export the task as a CUP file to an SD-card or mail it to yourself and load it up into your flight computer (LX, Oudie and others) or XCSoar. Soaring Weather: Aufwind comes with most crucial soaring forecasts already built-in: - Thermal strength - Cumulus cloudbase - Rain - Wind To get even more detailed soaring forecasts, you can login with your SkySight account in the app. Task Planner: Plan your task for the day interactively on the map overlaid with the weather forecast, airspaces and other relevant information. Thousands of waypoints are already built into Aufwind but you can import your own as well. You can export the planned task to an SD-card or email to use with your on-board flight computer or XCSoar. Airspaces & NOTAMs: Keep on top of local airspaces and NOTAMs and increase flight safety. Airspaces for many countries are already built into Aufwind but you can also import your own airspace files in OpenAir format into the app. ------------------- Aufwind is free to download and free to use.
