Apparently the answer to this question is you sit around listening to Beethoven while randomly exploring the bottoms in iGlide. After a while you find the update flarm data button and that’s all there is to it. I’ll find out for sure when I’m at the soaring club tomorrow.

It is actually not all that random, though the manual is not helpful. MenuSettingsData UpdatesFlarmNetDataDownload Lastest Flarmnet Data should do it. It will download directly into iGlide over your cellular data network. You will still see only the ICAO number for those Flarms not properly configured, which is all too common.

There is a neat feature on iGlide: touch one of the flarm targets (little glider symbols on the display), then the right arrow "" in the pop up. This will show all the flarm data on it, and offer the choice to assign a color to that particular glider. Henceforth, whenever it appears, it will appear in that color including its track. The assignment lasts until iGlide is shut down. A nice way to keep track of friends, rivals, team mates, trouble makers, etc.
