Non-towered airport: self-announce on the CTAF
Sample calls at C83
Byron has no operating control tower. Every call below goes out on the CTAF, 123.05, to the other aircraft, not to a controller. The runway shown is 05, 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.

If things change. Want flight following after departure? Call NorCal Approach on 123.85 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).
