Alma Municipal (4D9) radio calls

Non-towered airport: self-announce on the CTAF

Sample calls at 4D9

Alma Municipal has no operating control tower. Every call below goes out on the CTAF, 122.9, to the other aircraft, not to a controller. The runway shown is 17; 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 122.9. 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).
2. YouAlma Municipal traffic, Cessna Three One Six Zero Foxtrot, taxiing to runway one seven, Alma Municipal.
3. YouAlma Municipal traffic, Cessna Six Zero Foxtrot, departing runway one seven, departing the pattern to the north, Alma Municipal.
4. Announce until you are about 10 miles out; on the way back, start announcing at 10 miles (AIM 4-1-9 c 1, TBL 4-1-1).
5. YouAlma Municipal traffic, Cessna Three One Six Zero Foxtrot, one zero miles south, two thousand five hundred, landing Alma Municipal, Alma Municipal.
6. YouAlma Municipal traffic, Cessna Six Zero Foxtrot, entering left downwind runway one seven, full stop, Alma Municipal.
7. YouAlma Municipal traffic, Cessna Six Zero Foxtrot, left base runway one seven, Alma Municipal.
8. YouAlma Municipal traffic, Cessna Six Zero Foxtrot, final runway one seven, full stop, Alma Municipal.
9. YouAlma Municipal traffic, Cessna Six Zero Foxtrot, clear of runway one seven, Alma Municipal.

If things change. 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). Listen for ten miles before you arrive; most of what you want to know has already been said.
