Hoopa (O21) radio calls

Non-towered airport: self-announce on the CTAF

Sample calls at O21

Hoopa 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 14, which has a right-hand pattern; 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. YouHoopa traffic, Cessna Three One Six Zero Foxtrot, taxiing to runway one four, Hoopa.
3. YouHoopa traffic, Cessna Six Zero Foxtrot, departing runway one four, departing the pattern to the north, Hoopa.
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. YouHoopa traffic, Cessna Three One Six Zero Foxtrot, one zero miles south, two thousand five hundred, landing Hoopa, Hoopa.
6. YouHoopa traffic, Cessna Six Zero Foxtrot, entering left downwind runway one four, full stop, Hoopa.
7. YouHoopa traffic, Cessna Six Zero Foxtrot, left base runway one four, Hoopa.
8. YouHoopa traffic, Cessna Six Zero Foxtrot, final runway one four, full stop, Hoopa.
9. YouHoopa traffic, Cessna Six Zero Foxtrot, clear of runway one four, Hoopa.

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.
