Download the correct waypoint file for your instrument(s) from Airtribune. Go to Airtribune https://airtribune.com/wow2019/info at the bottom of the page in “downloads”. Here you will find a number of waypoint file formats. Depending on your instrument you may need GPSdump to manage the upload to your instrument. If you don’t have GPSdump go to http://www.gpsdump.no/body_gpsdump.htm (windows) choose the latest version 4.92 exe file and try that. For Mac http://www.gpsdump.no/body_mac.htm . Some instruments also have their own proprietary software for uploads eg Flychart for Flytec instruments.
The following formats are available;
CompeGPS, See You.cup, ozi.wpt, GPX, KML, Google Earth KMZ, winplot.dat
