What is the upper MSL altitude limit of the Class D airspace for Addison Airport?

• A. 2,500 feet MSL
• B. 3,000 feet MSL
• C. 11,000 feet MSL
• D. 4,000 feet MSL

Answer: (B)

The upper limit of Class D airspace is specifically defined by the air traffic control tower associated with the airport. In the case of Addison Airport, the designated upper limit is 3,000 feet MSL. This is a standard altitude for many Class D airspaces, which typically extend from the surface up to 2,500 or 3,000 feet MSL, depending on the airport's requirements and surrounding airspace. Class D airspace is designed to provide a controlled environment for aircraft operating in proximity to an airport where air traffic control services are available. Operators and pilots are required to communicate with the tower when operating within this airspace, ensuring safety and efficient traffic management. The defined ceiling at 3,000 feet MSL provides adequate vertical separation from surrounding airspace, particularly areas that may have higher classifications, thus maintaining a safe and organized flow of air traffic. Given this information, it is clear why 3,000 feet MSL is the correct answer for the upper altitude limit of Class D airspace over Addison Airport.
