What does Class C airspace typically extend to?

Class C airspace generally extends from the surface up to 4,000 feet above the airport elevation, with a radius of about 5 statute miles. The key characteristic of Class C airspace is its structure that typically starts at the surface and goes up to 4,000 feet above the airport elevation (MSL). This airspace facilitates the safe and efficient movement of aircraft in and out of busy airports while providing a specific air traffic control service.

While the answer indicates "up to 14,000 ft MSL," this could lead to some confusion as it implies that Class C airspace reaches higher altitudes. In fact, Class C airspace only extends to a maximum of 4,000 feet above the airport, not to 14,000 feet.

In summary, Class C airspace typically extends from the surface to 4,000 feet above the airport elevation. The provided answer is partially correct in the horizontal extent of 5 miles, but there is a misunderstanding in the maximum altitude, which is misrepresented.
