I am surprised ...

... that nobody has ever left a comment before.
This is a superb app which is fully integrated into my flight simulator cockpit. I actually run the app on two IPADs simultainously to see more data. Flight planning is the link to FSX or P3D is more stable than the simulator itself. Easy to setup, a massive amount of opportunities, and a full auto pilot included. Would never fly without anymore!! great job!
