What type of airspace does Class D represent?

Class D airspace is classified as controlled airspace surrounding an airport. This type of airspace typically extends from the surface up to a specific altitude, usually 2,500 feet above the airport elevation. The purpose of Class D airspace is to ensure safe and organized operations for both arriving and departing aircraft, particularly in busy terminal areas.

Within Class D airspace, communication with air traffic control (ATC) is required for all aircraft, which helps maintain safety by managing the flow of traffic. While it is primarily associated with airports that have an operational control tower, Class D airspace can be crucial for ensuring that both commercial and general aviation operations can occur without conflict.

The other options describe different airspace types. Uncontrolled airspace refers to areas where no ATC services are provided, which is characteristic of Class G airspace. Restricted airspace is designated for specific military or other activities and imposes certain restrictions on entry, while the reference to airspace for light aircraft only suggests limitations that do not apply to Class D, where a mix of aircraft can operate.
