Compute a safe altitude for your glider plane on a local flight. The app uses the GPS to display your relative position to an airfield and compute a safe glide altitude according to the selected L/D ratio. Database includes airfields of 34 European countries. You may add your own waypoints and fields. Require iPhone or iPad with GPS. Include Apple Watch app (models with GPS). CAUTION : The app does not monitor the terrain clearance, but only glide angle.
