What is the cloud clearance requirement for Class E airspace above 10,000 feet MSL?

The cloud clearance requirement for Class E airspace above 10,000 feet MSL is indeed a combination of visibility and distance from clouds. In this case, the correct answer specifies that pilots must maintain a visibility of 5 statute miles, as well as being 1,000 feet above, 1,000 feet below, and 1 statute mile horizontally from clouds.

This requirement is designed to ensure that pilots have adequate visual references in the airspace, promoting safety by minimizing the risk of collisions with other aircraft and allowing for the ability to see and avoid cloud formations. Maintaining these distances helps in providing sufficient separation from clouds for visual flight operations, which is crucial, especially at higher altitudes where weather conditions can be more variable and challenging.

The specific distances outlined in the correct option reflect the FAA's harmonizing of visual flight rules in various airspace classes, ensuring that all pilots operate under clear guidelines that enhance situational awareness while flying. Understanding these requirements is vital for safe navigation and compliance with aviation regulations.
