What defines Class D airspace?

• A. Airspace from the surface to 4,000 feet
• B. Airspace from the surface to 2,500 feet around controlled airports
• C. Typically uncontrolled airspace
• D. Designated for VFR flights only

Answer: (B)

Class D airspace is defined as airspace that extends from the surface up to 2,500 feet above the airport elevation surrounding an airport that has an operational control tower. This type of airspace is intended to provide a buffer for aircraft operating in the vicinity of the airport, allowing for safe management of both arrivals and departures. In Class D airspace, pilots are required to establish two-way radio communication with air traffic control before entering. It's specifically tailored for controlled airspace around airports where traffic typically includes a mix of general aviation and other aircraft, thus necessitating effective communication and coordination to maintain safety. Understanding the vertical limits of Class D airspace relative to nearby controlled airports is crucial for pilots when navigating and planning flights.
