When is airspace at an airport with a part-time control tower classified as Class D airspace?

1. Only during the day

2. Only when the control tower is operational

3. At all times

4. Only under specific weather conditions

The correct answer is: Only when the control tower is operational

Airspace around an airport with a part-time control tower is classified as Class D airspace when the control tower is operational. This classification is crucial because Class D airspace is associated with controlled airspace where air traffic control provides instructions for aircraft arriving and departing from the airport. The nature of a part-time control tower means that it may not be staffed and operational at all times, thus the designation of the airspace can change depending on whether or not the control tower is actively managing air traffic. When the tower is not in operation, the airspace could revert to a less controlled status, such as Class E or even Class G, depending on the specific circumstances and regulations. Understanding this concept is important for pilots as it directly impacts the operational procedures and communication requirements when flying near or into such airspace. By recognizing that Class D airspace only applies when the control tower is open, pilots can ensure they are adhering to the appropriate safety protocols and requirements for airspace management.
