Mobile Regional (KMOB) radio calls

Towered airport with a Class C surface area

Sample calls at KMOB

Mobile Regional has a Class C surface area: establish two-way communication with the approach control before entering, and keep it (AIM 3-2-4 c 3). A reply with your call sign, even "standby", establishes it. The calls below use runway 15; 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.
