What are the visibility requirements in Class B airspace?

Class B airspace is designed to accommodate high-density traffic around major airports. The visibility requirements in this airspace are set to enhance safety for both aircraft operating within the space and those transitioning through it. The correct visibility requirement is 3 statute miles, with the additional stipulation that the aircraft must be clear of clouds.

This requirement ensures that pilots have adequate visual references to navigate safely and avoid collisions with other aircraft. Clear of clouds means that pilots should maintain visual separation from clouds, which enhances their ability to see and be seen by other aircraft, as well as ground references. Meeting this visibility and cloud clearance standard is crucial for maintaining safe operations, especially in busy airspace where multiple aircraft are working in proximity to one another.

The other options do not align with the regulations for Class B airspace. Lower visibility requirements would not ensure the same level of safety, which is why the regulations have been established at this specific standard.
