What is the vertical limit of Class D airspace?

Class D airspace typically extends from the surface up to 2,500 feet above ground level (AGL). This is the upper vertical limit for Class D airspace, which is designed to support airport operations and manage air traffic around smaller airports that have an operational control tower. The purpose of establishing this airspace is to provide a controlled environment for aircraft to safely operate in close proximity to an airport.

While the specific vertical limits may vary based on the local regulations and the surrounding terrain, the standard height of 2,500 feet AGL applies to most Class D airspaces. This allows for sufficient altitude for both departing and arriving aircraft, as well as providing a buffer for those operating in the vicinity of the airport.
