Hi Sanal.

There is a flight plan converter that converts FS Flight Plans into CIVA INS flight that you can load into the INS. Get it here.

A few things you need to know for the converted Flight Plans to work correctly.

1. The converted Flight Plans must be saved in the FSX\civa\ADEU folder.
2. You must save the converted file in the above location BEFORE you start FSX or you can't see them with the INS and so that means you can't load them.
3. A text file is made with the same name as the saved flight plan name which guides you to when you need to load the next part of the flight plan. Keep it close at hand when doing your flight. ;)
