What is required regarding cloud distance and ground visibility when operating under special VFR in Class D airspace?

When operating under special VFR in Class D airspace, the requirement is to remain clear of clouds while ensuring that ground visibility is at least 1 statute mile. This regulation is in place to ensure that pilots have sufficient visibility to navigate safely and avoid potential collisions with other aircraft or obstacles on the ground while flying at lower altitudes.

The focus on ground visibility of at least 1 statute mile allows pilots to maintain visual separation from other aircraft and enables them to adhere to visual flight rules even in less than ideal conditions. By mandating that pilots remain clear of clouds, this rule emphasizes safety by ensuring that pilots can see and be seen, which is critical during maneuvering in congested airspace, such as near airports.

In terms of other options, they either specify incorrect cloud clearance requirements or have different visibility standards that do not align with the regulations for special VFR operations. Understanding these requirements helps pilots make informed decisions and ensures compliance with aviation safety standards.
