Marion County/Brown Field (KAPT) radio calls

Non-towered airport: self-announce on the CTAF

Sample calls at KAPT

Marion County/Brown Field has no operating control tower. Every call below goes out on the CTAF, 122.8, to the other aircraft, not to a controller. The runway shown is 04; use whichever runway the wind and the traffic dictate on the day.

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.

1. Tune 122.8. Nobody clears you; you announce and you listen. The airport name goes at the start and the end of every call, and the runway is always a number, never "the active" (AIM 4-1-9 g 8).

If things change. Want flight following after departure? Call Chattanooga Approach on 119.2 once clear of the pattern: identification, type, position, altitude, destination, "request VFR flight following" (AIM 4-1-18 a 3). Do not use "any traffic in the area, please advise"; the AIM says it is not to be used under any condition (AIM 4-1-9 g 1).
