Not sure if I understand your question?
I also have a question as to importing SimBrief flight plans CJ4?
No problem getting the Simbrief flight plan into the CJ4 FMC. but now the ATC knows nothing about this flight plan?
If I import it to Microsoft simulator the ATC works OK.
So do I have to import the flight plan into both MSF and CJ4 in order for both to work?
Or am I missing something?
