Non-towered airport: self-announce on the CTAF

Sample calls at KCVO

Corvallis Municipal has no operating control tower. Every call below goes out on the CTAF, 123.075, 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 123.075. 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. YouCorvallis Municipal traffic, Cessna Three One Six Zero Foxtrot, taxiing to runway one zero, Corvallis Municipal.
  3. YouCorvallis Municipal traffic, Cessna Six Zero Foxtrot, departing runway one zero, departing the pattern to the north, Corvallis 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. YouCorvallis Municipal traffic, Cessna Three One Six Zero Foxtrot, one zero miles south, two thousand five hundred, landing Corvallis Municipal, Corvallis Municipal.
  6. YouCorvallis Municipal UNICOM, Cessna Six Zero Foxtrot, one zero miles south, request wind and runway information, Corvallis Municipal.
  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.
  8. YouCorvallis Municipal traffic, Cessna Six Zero Foxtrot, entering left downwind runway one zero, full stop, Corvallis Municipal.
  9. YouCorvallis Municipal traffic, Cessna Six Zero Foxtrot, left base runway one zero, Corvallis Municipal.
  10. YouCorvallis Municipal traffic, Cessna Six Zero Foxtrot, final runway one zero, full stop, Corvallis Municipal.
  11. YouCorvallis Municipal traffic, Cessna Six Zero Foxtrot, clear of runway one zero, Corvallis Municipal.

If things change. Want flight following after departure? Call Cascade Approach on 120.25 once clear of the pattern: identification, type, position, altitude, destination, "request VFR flight following" (AIM 4-1-18 a 3). 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).
