Brooks Field (KRMY) radio calls

Marshall, MIICAO KRMY · FAA RMY

Brooks Field is a non-towered airport in Marshall, MI. Nobody clears you to do anything: you self-announce on the CTAF, 122.8, as Brooks Field Traffic, with the airport name at the start and end of each call. The approach control for the area is Great Lakes Approach on 121.2, which is who you call for VFR flight following.

No Class B, C, D or E surface area is designated for this airport in the FAA data, so the airspace at the surface is Class G.

Non-towered airport: self-announce on the CTAF

Sample calls at KRMY

Brooks 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 10; 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).
  2. YouBrooks Field traffic, Cessna Three One Six Zero Foxtrot, taxiing to runway one zero, Brooks Field.
  3. YouBrooks Field traffic, Cessna Six Zero Foxtrot, departing runway one zero, departing the pattern to the north, Brooks Field.
  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).

If things change. Want flight following after departure? Call Great Lakes Approach on 121.2 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).
