Emi, the flightplans you see on the ADEU are not MSFS flightplans, they are pre-saved INS flighplans that were installed with the gauge and are meant to be used as example. I believe one corresponds to the 'Tutorial' document found under 'FSX root folder/Civa/Docs' which I highly recommend you read, along with the other manuals in that folder. the videotutorials in the link above are also very useful.

Unfortunately, MSFS flighplans cannot be imported directly into the CIVA INS. You will have to enter them manually in the unit, waypoint by waypoint.

What I do when creating a flightplan is select 'direct GPS', then pick my waypoints myself along the way, noting down their coordinates on a piece of paper, because they won't appear on the MSFS 'Kneeboard - flight plan' screen. Be sure to use some VORs in your route, which you can use to update your position and re-calibrate your INS during flight.

Hope this helps

Cheers

Nico
