Center Frequency Range Restriction


Is there any option/way to restrict tuning into Center Frequency , and only available when an aircraft is within certain miles of distance from the FIR boundry ?

Or if it only available to IFATC’s

I mean I know on the ES at least you have to be within 400nm of the station (i.e. the airport the ATC loaded up at), even if you are technically inside the FIR. I assumed it was the same on TS but is it not?

No, this is only for expert server

Yes, it is on TS, but surprisingly a lot of Center stations have a smaller area than the 400nm radius from the station. Unfortunately people still tune in to Center even when they are not “officially” in the airspace on ES
