Airspace that extends from the surface to 2500 ft AGL is classified as what?

Airspace that extends from the surface to 2500 feet above ground level (AGL) is classified as Class D airspace. Class D airspace is typically found around airports with an operational control tower and is designed to help manage both aircraft that are departing or arriving and those that are flying in the vicinity of the airport.

In Class D airspace, pilots are required to establish two-way communication with air traffic control before entering and are expected to follow specific operating procedures to ensure safety and efficiency. This classification is particularly focused on creating a safer environment for aircraft operating in proximity to airports.

The other classifications mentioned, such as Class C, Class B, and Class E, operate under different parameters. Class C airspace, for example, is often bigger and encompasses both the surface and higher altitudes, typically from the surface up to 4000 feet, with a specific radius around busy airports. Class B airspace is more extensive and is particularly focused around major airports, extending from the surface to upwards of 10,000 feet AGL in some cases. Class E airspace can be more variable and generally starts at either the surface or a designated altitude and extends up to but not including 18,000 feet.
