Non-towered airport: self-announce on the CTAF

Sample calls at KUMP

Indianapolis Metro 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 15; 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).

  3. YouIndianapolis Metro traffic, Cessna Six Zero Foxtrot, departing runway one five, departing the pattern to the north, Indianapolis Metro.

If things change. Want flight following after departure? Call Indianapolis Approach on 127.15 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).
