What is the required cloud clearance in controlled airspace?

In controlled airspace, the required cloud clearance is 1,000 feet vertically and 3 miles horizontally from clouds. This regulation ensures that pilots maintain a safe distance from clouds to avoid potential collisions with other aircraft operating in or near the clouds, as well as to promote visual navigation.

To maintain adequate separation, pilots flying VFR (Visual Flight Rules) in controlled airspace are expected to comply with these visibility and cloud clearance requirements. This standard helps mitigate risk in air traffic environments where multiple aircraft may be maneuvering in proximity.

Other options do not meet the established regulations for cloud clearance in controlled airspace. For instance, more relaxed requirements in other airspace categories might apply, but in controlled airspace, adhering to this specific 1,000-foot and 3-mile criteria is crucial for safe operations.
