Sample calls at KCMY
Sparta/Fort Mc Coy has a Class D surface area: establish two-way communication with the tower before entering (AIM 3-2-5 b 3).

The aircraft is the AIM’s own example, Cessna Three One Six Zero Foxtrot; the squawk codes, altitudes and headings are illustrative. Frequencies, station names and runway numbers are this airport’s, from the FAA data.
