What is the minimum separation required from clouds in controlled airspace up to 1,200 feet AGL?

In controlled airspace, the minimum separation from clouds for aircraft flying below 1,200 feet AGL is 500 feet vertically and 2,000 feet horizontally. This standard ensures that pilots maintain a safe distance from cloud formations, which is crucial for visual flight rules (VFR) operations where visual reference to the ground is necessary.

Choosing 500 feet is correct because it aligns with the regulatory requirements for maintaining adequate separation from clouds while flying in controlled airspace. This distance allows pilots to have clear visibility of their surroundings, which is essential for avoiding obstacles and ensuring the safety of flight operations.

Clouds can pose a significant hazard for pilots by obstructing visibility and potentially leading to loss of control if an aircraft inadvertently enters instrument meteorological conditions. Thus, the 500-foot minimum vertical separation is established to mitigate these risks effectively while allowing for safe navigation and situational awareness.
