Non-towered airport: self-announce on the CTAF

Sample calls at T94

Twin-Oaks 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 12; 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. YouTwin-Oaks traffic, Cessna Three One Six Zero Foxtrot, taxiing to runway one two, Twin-Oaks.
  3. YouTwin-Oaks traffic, Cessna Six Zero Foxtrot, departing runway one two, departing the pattern to the north, Twin-Oaks.
  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. YouTwin-Oaks traffic, Cessna Three One Six Zero Foxtrot, one zero miles south, two thousand five hundred, landing Twin-Oaks, Twin-Oaks.
  6. YouTwin-Oaks traffic, Cessna Six Zero Foxtrot, entering left downwind runway one two, full stop, Twin-Oaks.
  7. YouTwin-Oaks traffic, Cessna Six Zero Foxtrot, left base runway one two, Twin-Oaks.
  8. YouTwin-Oaks traffic, Cessna Six Zero Foxtrot, final runway one two, full stop, Twin-Oaks.
  9. YouTwin-Oaks traffic, Cessna Six Zero Foxtrot, clear of runway one two, Twin-Oaks.

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.
