Quick answers, no account. They use the same maths as the app.

Pick a place, your drone and an altitude: get the go/no-go for this hour from wind and gusts at height, rain, visibility, Kp and daylight.

Turn a 10 m wind forecast into the wind and estimated gusts at 30, 60, 90 and 120 m, with the power law and your drone’s limits.

Live Kp index from NOAA, weighted for your latitude, with a plain “GPS: normal / may be degraded” line and the next 24 hours.

Convert wind speed between m/s, km/h, mph and knots and see the Beaufort force, with the full Beaufort table for drone pilots.
