I’ve “flown” both models of Cygnus, and they work like a charm. On one test of the system that I did at Oshkosh AirVenture at Redbird’s exhibit, I decided to be funny and set the flight sim I was flying, a Redbird TD2, to take off from Lakeland Linder Regional Airport, home to the Sun ‘n Fun fly-in. The iPad, which was still verifiably in Oshkosh, Wisconsin, was fooled by Cygnus into thinking it was in Lakeland, and while we flew I used ForeFlight to follow by flight path, down to pinching and zooming into the moving map display and selecting “nearest” airports and their approach charts.
