What is the horizontal cloud clearance requirement for Class C airspace?

In Class C airspace, the horizontal cloud clearance requirement is established to ensure that pilots can maintain visual separation from clouds, enhancing safety during operations. Specifically, pilots must remain at least 2,000 feet horizontally from any cloud. This requirement is designed to reduce the risk of collisions with clouds, particularly for pilots flying under visual flight rules (VFR), and to ensure that they have adequate visual references while navigating. By maintaining this distance from clouds, pilots can better visualize the horizon and surrounding terrain, contributing to safer flight operations in busy airspace. Class C airspace is typically around airports with moderate traffic, making it even more critical to ensure visual separation from clouds to avoid any potential flight safety issues.
