Sample calls at 3N8

Mahnomen County 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 09; 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.
