What defines Class D airspace?

• A. Airspace above 10,000 feet AGL
• B. Airspace without any control towers
• C. Airspace surrounding an airport with an operational control tower
• D. Airspace for exclusively military operations

Answer: (C)

Class D airspace is specifically defined as the airspace surrounding an airport that operates with an active control tower. This type of airspace typically extends upward from the surface to a designated ceiling, which is generally not higher than 2,500 feet above ground level (AGL). The key characteristic of Class D airspace is the presence of air traffic control services, which manage the traffic within this space to ensure safety and efficiency for both aircraft operating in the vicinity of the airport and those flying in and out of it. The control tower serves to coordinate the movements of aircraft on the ground and in the airspace surrounding the airport, providing important guidance for both arrival and departure procedures. In Class D airspace, pilots are required to establish two-way radio communication with the tower before entering, which helps maintain situational awareness and safety among various aircraft. The other choices do not accurately define Class D airspace. For instance, airspace above 10,000 feet AGL pertains more to higher classifications such as Class E and is not exclusive to Class D. Likewise, airspace without control towers would more likely refer to uncontrolled airspace, which does not fit the definition of Class D. Finally, airspace designated for exclusively military operations encompasses entirely different classifications
