When I send a flightplan from simbrief to MSFS on the cj4 working mod, it does not give the option to request an IFR clearance. I execute after input but still nothing. Help?
Because they programmed the fmc by themself and do not use the default one as far as I understood.
You need to use the ‘synchronize with atc’-feature in the fmc of working title (…as documented on their site…)
