Question

Question restatement: Air traffic control tower Class D airspace is usually:

Option 1: From FL 180 to FL 600. This is not characteristic of Class D airspace. Those flight levels describe high-altitude controlled airspace (more typical of upper enroute airspace), whereas Class D is a surface-to-specified altitude airspace surrounding smaller airports with towers. So this option misstates vertical boundaries entirely.

Option 2: 4nm (5sm) radius and 2,500 AGL. This aligns with the conventional description of Class D airspace: a core around the airport with a radius of about 4 nautical miles (which is 4 NM, roughly 5 statute miles) and a top at 2,500 feet above ground level (AGL). This is the standard configuration used to define many Class D zones.

Option 3: 10nm radius and up to 4,000 AGL. A 10 NM radius is larger than typical for Class D, and 4,000 AGL is higher than the standard top of 2,500 AGL for Class D in most cases. This combination would not match the usual Class D dimensions and sounds more like an expanded control area, not the standard Class D around a towered airport.

Option 4: 30nm radius and up to 10,000 MSL. A 30 NM radius is characteristic of larger terminal or enroute airspace sectors, not the Class D surrounding a towered airport. Also, 10,000 MSL (mean sea level) is a much higher ceiling than standard Class D, which is defined above the surface up to 2,500 AGL.

Reasoning summary: The core criteria defining Class D airspace around a control-towered airport are a surface-based area with a radius typically around 4 NM and a top at 2,500 feet AGL. Options 1, 3, and 4 either misstate the vertical limits (too high or too low) or exaggerate the horizontal radius beyond the typical Class D scope, making them inconsistent with standard Class D definitions.

Final note on which option matches the standard description: Option 2 accurately reflects the common Class D dimensions of a 4 NM radius and 2,500 AGL, whereas the other options deviate from these typical boundaries.
