All of Charleston International Airport — runways, frequencies, charts and live weather

Before taxi Charleston

ATIS 124.75: A recorded loop of the field's weather, active runway and any notices, updated hourly or whenever conditions change. Listen before your first call, and tell the controller which letter you have so they do not read it to you again.
Clearance 127.325: Clearance delivery issues your IFR clearance, and at busier fields your VFR departure instructions and squawk code. Call before you request taxi, with the ATIS letter and your intended direction of flight.

Taxi & takeoff Charleston

Ground 121.9: Ground control owns every taxiway and inactive runway on the field. Call for taxi with your position and destination on the field. You need an explicit clearance to cross any runway, including one that is not in use.
Tower 126.0: Tower owns the active runways and the surrounding surface area. Call before entering the surface area inbound, and hold short until you are cleared to take off or to cross.

Departure & arrival Charleston

App/Dep 120.7 (151-330 · BAGGY · OSPRI arrivals; LGRHD · STUNO departures), 121.275 (331-150 · AMYLU arrivals; MLTRE · PLMTO · SWPFX departures): One radar controller working both arrivals and departures — normal at a smaller TRACON. The same frequency takes your climb out and your inbound call.

Also

UNICOM 122.95: A ground station run by the FBO rather than the FAA, for fuel, parking and airport services. Use it for services. Where the field has no separate CTAF, the same frequency doubles as the advisory frequency.
