Agra. If you had followed the NAS educational material you would have been monitoring the CTAF if in the approach and departure airspace of the airport. You would have heard the taxiing call and given a position report on the CTAF if necessary.
ATC would not have been involved and with less frequency loading may in future have been able to provide a class E separation service to the IFR aircraft when IMC exists .
Since I was cruising at 8500', and some 30 miles from the airport, CTAF would have been completely inappropriate. There were other CTAFs around - which one should I have been monitoring? And, to head off the next obvious riposte, if I'd been on 126.7 or 121.5, I'd have heard nothing at all.
We were both in VMC, and the frequency was in no way "loaded." In fact he seemed quite happy to hear from me, and no A380s were endangered.
And Agra. Don't try that in any other country in the world . You will end up with licence action.
I wasn't
in any other country in the world.
