Overview
Class C Airspace is found around airports that have a significant level of traffic but do not meet the traffic thresholds or airspace complexities that would necessitate Class B airspace. Although each Class C airspace is designed according to the needs of the area, it generally has two tiers: a 5 NM radius ring that begins at the surface and goes to 4,000 feet AGL and a 10 NM radius ring that begins at 1,200 feet AGL and extends to 4,000 feet AGL. Class C airspace indicates that radar approach control is available. From the perspective of a flight instructor, Class C airspace is a great place to introduce a student to communicating with air traffic control.
