Lake Chelan (S10) radio calls

Chelan, WAFAA identifier S10; no ICAO code assigned

Lake Chelan is a non-towered airport in Chelan, WA. Nobody clears you to do anything: you self-announce on the CTAF, 122.9, as Lake Chelan Traffic, with the airport name at the start and end of each call, and a UNICOM on 122.95 can give you the wind and runway in use.

No Class B, C, D or E surface area is designated for this airport in the FAA data, so the airspace at the surface is Class G.

Non-towered airport: self-announce on the CTAF

Sample calls at S10

Lake Chelan 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, 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. YouLake Chelan traffic, Cessna Three One Six Zero Foxtrot, taxiing to runway zero two, Lake Chelan.
  3. YouLake Chelan traffic, Cessna Six Zero Foxtrot, departing runway zero two, departing the pattern to the north, Lake Chelan.
  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. YouLake Chelan traffic, Cessna Three One Six Zero Foxtrot, one zero miles south, two thousand five hundred, landing Lake Chelan, Lake Chelan.
  6. YouLake Chelan UNICOM, Cessna Six Zero Foxtrot, one zero miles south, request wind and runway information, Lake Chelan.
  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. YouLake Chelan traffic, Cessna Six Zero Foxtrot, entering left downwind runway zero two, full stop, Lake Chelan.
  9. YouLake Chelan traffic, Cessna Six Zero Foxtrot, left base runway zero two, Lake Chelan.
  10. YouLake Chelan traffic, Cessna Six Zero Foxtrot, final runway zero two, full stop, Lake Chelan.
  11. YouLake Chelan traffic, Cessna Six Zero Foxtrot, clear of runway zero two, Lake Chelan.

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.
