At breakfast this morning, I mentioned I'd asked Ricky, the AVL controller, how ADS-B Out was affecting his day-to-day operations.? He said previously their aircraft position information was restricted to primary radar echoes and Mode C transmissions, both limited by the mountains at AVL.? With the addition of ADS-B ground stations, he said ATC now receives near real time aircraft position information from ADS-B Out-equipped aircraft over a much wider area.? With this additional coverage,?there had been discussion of expanding the AVL Class C shelf to as much as 20-25 nautical miles from the current 10 nm.? I'm not aware of any current Class C airspace shelves that extend more than 10 nm, but there is an FAA proposal to grow the Fort Lauderdale (FLL) Class C shelf to 25 nm (see?).? Any change would be years away, but I'm not surprised.

You’re not going to get away that easy Alex. ??

You stated that there was a provision or exception to the transponder requirement for non electric aircraft to enter class C with only radio contact. ? I said there was no such provision specific to non electric system aircraft And that there was a provision for all aircraft that with prior notice.

However ATC can direct an aircraft to enter.

But I’m really a nice guy and even though I am correct I will not require you or Brian to buy me breakfast.?

It’s ok to have enemies, it means you stood up for something.

Interesting. Darwin and I were both right this morning ... I can take the CallAir into Class C but I have to make a reservation with ATC .. can't fly over it, though I don't know why I would.
