Class C Airspace

Controlled airspace surrounding airports with an operating control tower and radar approach control that serve a moderate volume of traffic. Depicted as solid magenta lines on sectional charts, it typically extends from the surface to 4,000 feet AGL in a two-layer configuration. Pilots must establish two-way radio communication with ATC before entering and must have a Mode C transponder. VFR minimums are 3 SM visibility, 500 below, 1,000 above, and 2,000 horizontal from clouds.
