Class C airspace typically shifts from the surface to what altitude?

Class C airspace is designed to manage air traffic around busy airports while providing a standard level of air traffic control services. Typically, Class C airspace extends from the surface up to an upper limit of 4,000 feet above the airport elevation. This vertically structured airspace allows for both departing and arriving aircraft to operate in a safe and organized manner.

Understanding the altitude limit is important for pilots to ensure they are adhering to the appropriate regulations and operating within controlled airspace. This altitude from the surface up to 4,000 feet creates a buffer that helps maintain separation between aircraft operating at lower altitudes, as well as those departing or arriving at the airport.

The other options would suggest limits beyond what Class C airspace encompasses, indicating misunderstandings of airspace designations. For instance, 2,500 feet above the airport elevation does not encompass the full vertical extent of Class C airspace, while the other two options reference much higher elevations typical of different airspace classifications, such as Class A or Class E airspace.
