Class C airports(Redirected from Class C Airports)
United StatesThe airspace around medium size US airports is ICAO Class C. This protects the approach and departure paths from aircraft not under air traffic control. All aircraft inside Class C airspace are subject to air traffic control. Traffic operating under VFR must be in communication with a controller before it can enter. The airspace is similar to Class B's "upside down wedding cake" but much smaller. The inner most ring extends from the surface area around the airport to typically 4,000 ft (1220 m) above ground level (AGL). One outer ring surrounds it with a floor from about 1,500 ft (460 m) AGL to the 4,000 ft (1220 m) AGL ceiling. (listed by state and IATA Airport Code/ICAO Airport Code)

CanadaCanada uses Class C for busy airports with commercial airline service. The size of the airspace however is similar to Class B airports in the United States. The inner most ring extends from the surface area around the airport to typically 12,500 ft (3810 m) MSL. Several outer rings surround it with progressively higher floors to allow traffic flow into nearby airports.
