Non-towered airport: self-announce on the CTAF

Sample calls at KECS

Mondell Field has no operating control tower. Every call below goes out on the CTAF, 122.8, to the other aircraft, not to a controller. The runway shown is 14, 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 122.8. 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).
