Missoula Montana (KMSO) radio calls

Towered airport with a Class D surface area

Sample calls at KMSO

Missoula Montana has a Class D surface area: establish two-way communication with the tower before entering (AIM 3-2-5 b 3). A reply that uses your call sign, even "standby", establishes it; "aircraft calling, standby" does not. The calls below use runway 08; the tower assigns the runway in use 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. The tower operates 0600-2200 local. Outside those hours the airport is a non-towered field: self-announce on the CTAF, 118.4 with the airport name first and last, and the surface area reverts to Class E or Class G as published in the Chart Supplement.
