Try that on EHLE where multicom and FSS have the same freq. and you never get 'online' with control/centre.

I googled for an hour, but could not find a way to read the control/center frequencies out of P3D. My EFB is not giving them either (don't know if that's a shame). So I'm stuck to the above mentioned procedure. PF3 'reads' those frequencies 'somewhere'. If someone knows a way to find out the active frequency for the area, or any other way to elegantly dial in (not via FSS) it would be highly appreciated.
And one more thing....
The other way around works. Departing from a mega airport on an IFR flight plan with an uncontrolled airfield as destination. I noticed that PF3 puts you on approach (while actually there is no APP freq. according to P3D data). It would be nice if one could 'cancel IFR', fly the circuit using multicom freq. and land. Or is it just Hotkey 8 'Airport in sight'that does it?
