What altitudes does Class C airspace extend from?

Class C airspace typically extends from the surface up to an altitude of 4,000 feet above ground level (AGL). This airspace is established around airports with a certain level of air traffic, providing services to both VFR (Visual Flight Rules) and IFR (Instrument Flight Rules) traffic. The structure of Class C airspace generally includes an inner core that extends from the surface to 4,000 feet AGL, with a surrounding shelf that extends horizontally, usually at a higher altitude. Such design serves to create a safer operating environment by ensuring that air traffic control can provide separation and assistance to all aircraft operating within this space.

While there are other classes of airspace with different altitude specifications, understanding the specific limits of Class C is crucial for pilots operating in or near these areas.
