Non-towered airport: self-announce on the CTAF

Sample calls at KCIU

Chippewa County International has no operating control tower. Every call below goes out on the CTAF, 123.0, to the other aircraft, not to a controller. The runway shown is 10; 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 123.0. 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. YouChippewa County International traffic, Cessna Three One Six Zero Foxtrot, taxiing to runway one zero, Chippewa County International.
  3. YouChippewa County International traffic, Cessna Six Zero Foxtrot, departing runway one zero, departing the pattern to the north, Chippewa County International.
  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).

  7. A UNICOM operator, if one is on, answers with the wind and the runway in use (AIM 4-1-9 h). If nobody answers, choose the runway from the wind and the pattern traffic you can hear.

  9. YouChippewa County International traffic, Cessna Six Zero Foxtrot, left base runway one zero, Chippewa County International.

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.
