If I’m 19nm from an airport, and I call inbound - on tower frequency - and as I turn to right base as they told me to, approach asks me to contact them, what should I do?
This happened earlier today, and so I responded to tower’s directions that sent me to right base, and contacted the approach who had by this time asked that I contact them two times. So I did, and before long (an understandably confused) tower, was asking me to contact them (again). So I asked to change frequency, but approach told me to remain with them.
Which ATC service should I be connected to, and at what distance from the airport?
