Class C: This is the controlled airspace above 7,500 feet and surrounding major airports. Both IFR and VFR flights are permitted and both require ATC clearance and separation service is to be provided by ATC. Class G: This airspace is uncontrolled.

Unless otherwise authorized or required by ATC, no person may operate an aircraft at or below 2,500 feet above the surface within 4 nautical miles of the primary airport of a Class C airspace area at an indicated airspeed of more than 200 knots (230 mph).
Class Charlie Airspace surrounds those airports that have an at least operational Air Traffic Control Tower (ATCT), and Terminal Radar Approach Controls (TRACON) These air traffic control agencies provide radar services which apply whenever operating within Class C airspace as depicted on various aeronautical charts.
Class Charlie or Class C airspace is a busy category of controlled airspace found near mid-size airports that service both general aviation and airline traffic. The primary airport in a Class C airspace has both an operational Air Traffic Control Tower (ATCT) as well as Terminal Radar Approach Controls (TRACON).
Class C airspace is designed to establish and maintain safe separation of mixed general aviation and airline traffic. It is usually upside-down wedding cake shaped and depicted on charts with two bold magenta rings along with numbers indicating the airspace floor and ceiling within each ring.
Definition. Generally, that airspace from the surface to 4,000 feet above the airport elevation (charted in MSL) surrounding those airports that have an operational control tower, are serviced by a radar approach control, and that have a certain number of IFR operations or passenger enplanements.
How to get Approval to Enter Class C Airspace. The approval needed to enter Class C airspace is like Class D in that you do not need a specific clearance, but you do need to establish two-way communication with control. To be able to enter Class C airspace, a pilot must contact ATC prior to arrival.
Like most controlled airspace, ALL pilots must notify and receive approval from the FAA to fly in Class C airspace. Pilots must also follow the necessary procedure to receive permission. Approval cannot be granted by control towers individually; the request must be sent using one of two methods.
Unless otherwise authorized or required by ATC, no person may operate an aircraft at or below 2,500 feet above the surface within 4 nautical miles of the primary airport of a Class C airspace area at an indicated airspeed of more than 200 knots (230 mph).
Class C Airspace (Mandatory Radar)A shelf area with an outer radius of 10 nautical miles surrounds the core area. It extends from 1200 feet AGL to 4000 feet AGL. The airspace is depicted on charts as 2 concentric magenta circles.
Class B airspace surrounds the busiest airports from the surface to 10,000 feet MSL. The dimensions of Class B airspace vary depending on the needs of the airport. Class C airspace extends from the surface to 4,000 feet MSL.
Class C Airspace OverviewClass C Airspace shows up on the map around larger airports as a solid Magenta line. They have a layer similar to class B airspace, but on a smaller scale and typically with only one other shelf.
Since Class D is controlled airspace all the way to the surface, you can't fly VFR when the ceiling (a broken or overcast cloud layer) is less than 1000' AGL (FAR 91.155 (c)), or when the visibility is less than 3 SM.
Class A airspace is more restrictive than Class B, Class C, Class D, Class E, or Class G airspace. Class B airspace is more restrictive than Class C, Class D, Class E, or Class G airspace.
Entering Class C airspace requires a mode C transponder, and two-way communications (meaning that ATC says your tail number). To transition through or land at a Class C airspace, make the request within 20 miles.
Class C ArrivalIf you are not receiving flight following, around 20NM from the airport and prior to entering Class C airspace contact approach control on the frequency listed on your VFR chart. On initial contact you should provide your callsign, location, altitude, request, and the ATIS code.
