Non-towered airport: self-announce on the CTAF

Sample calls at U37

Midway 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 02; 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. YouMidway traffic, Cessna Three One Six Zero Foxtrot, taxiing to runway zero two, Midway.
  3. YouMidway traffic, Cessna Six Zero Foxtrot, departing runway zero two, departing the pattern to the north, Midway.
  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. YouMidway traffic, Cessna Three One Six Zero Foxtrot, one zero miles south, two thousand five hundred, landing Midway, Midway.
  6. YouMidway traffic, Cessna Six Zero Foxtrot, entering left downwind runway zero two, full stop, Midway.
  7. YouMidway traffic, Cessna Six Zero Foxtrot, left base runway zero two, Midway.
  8. YouMidway traffic, Cessna Six Zero Foxtrot, final runway zero two, full stop, Midway.
  9. YouMidway traffic, Cessna Six Zero Foxtrot, clear of runway zero two, Midway.

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.
