Washington Dulles International (KIAD) radio calls

Towered airport inside Class B

Sample calls at KIAD

Washington Dulles International sits inside Class B airspace: an explicit ATC clearance is required before entering it (AIM 3-2-3 b), and you will hear "cleared into the Bravo" or you stay out. The calls below use runway 01C; 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.
