Napa County (KAPC) radio calls

Towered airport with a Class D surface area

Sample calls at KAPC

Napa County 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 01L; 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.

1. Listen to the ATIS on 124.05 first and note the letter; "with Information (letter)" on your first call lets the controller skip the weather (JO 7110.65 3-10-1).
