What are the cloud clearance requirements in D airspace?

The cloud clearance requirements in D airspace stipulate that pilots must maintain 3 statute miles of visibility and be clear of clouds. This regulation ensures that pilots have sufficient visual reference to navigate and avoid obstacles safely, thus enhancing situational awareness during flight operations in this airspace classification.

In D airspace, which often encompasses airports with an operational control tower, the emphasis is on allowing pilots to operate visually while still maintaining a safe distance from clouds, thus reducing the risks associated with potential cloud obscuration. The requirement for clarity and visibility is crucial for effective traffic management, especially since D airspace typically handles both IFR (Instrument Flight Rules) and VFR (Visual Flight Rules) traffic.

This option reflects the established regulations and safety standards for flying in D airspace and is aligned with FAA guidelines. The other options incorrectly suggest either more restrictive conditions or insufficient visibility and cloud clearance, which do not conform to the operational requirements in D airspace.
