In a self-announce radio broadcast at a non-towered airport, how is an inbound aircraft's position relative to the airport typically stated?

Why: The FAA study guide describes the standard inbound broadcast: "This initial radio call will also include the position the aircraft is in relation to north, south, east or west from the airport. For example: Town and Country traffic, Cessna 123 Bravo Foxtrot is 10 miles south inbound for landing, Town and Country traffic."

• Invents a GPS-coordinate convention; the self-announce phraseology described uses cardinal direction and distance in miles, not a latitude/longitude readout.
• Confuses the aircraft's own heading with its position relative to the airport; the broadcast states where the aircraft is (e.g., "10 miles south"), not merely the direction it is pointed.
