Grosse Ile Municipal (KONZ) radio calls

Non-towered airport: self-announce on the CTAF

Sample calls at KONZ

Grosse Ile Municipal 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 04, 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 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).
2. YouGrosse Ile Municipal traffic, Cessna Three One Six Zero Foxtrot, taxiing to runway zero four, Grosse Ile Municipal.
3. YouGrosse Ile Municipal traffic, Cessna Six Zero Foxtrot, departing runway zero four, departing the pattern to the north, Grosse Ile Municipal.
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. YouGrosse Ile Municipal traffic, Cessna Three One Six Zero Foxtrot, one zero miles south, two thousand five hundred, landing Grosse Ile Municipal, Grosse Ile Municipal.
6. YouGrosse Ile Municipal UNICOM, Cessna Six Zero Foxtrot, one zero miles south, request wind and runway information, Grosse Ile Municipal.
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. YouGrosse Ile Municipal traffic, Cessna Six Zero Foxtrot, entering left downwind runway zero four, full stop, Grosse Ile Municipal.
9. YouGrosse Ile Municipal traffic, Cessna Six Zero Foxtrot, left base runway zero four, Grosse Ile Municipal.

If things change. Want flight following after departure? Call Detroit Approach on 134.3 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).
