What is the required visibility and cloud clearance below 10,000' MSL in Class E airspace?

The correct answer specifies that in Class E airspace below 10,000' MSL, the visibility requirement is 3 statute miles, along with cloud clearance of 1,000 feet above the clouds, 500 feet below the clouds, and 2,000 feet horizontal from the clouds. This aligns with the Federal Aviation Administration (FAA) regulations governing visual flight rules (VFR) and the specific guidelines for Class E airspace.

In Class E airspace, which is typically utilized for transitioning purposes and when flying below 10,000 feet, maintaining adequate visibility and separation from clouds is essential for safe flight operations. The visibility of 3 statute miles ensures that a pilot has enough visual reference to navigate safely, while the cloud clearance rules prevent potential risks associated with flying too close to cloud formations, which could obstruct visibility and lead to conflicts with other aircraft. The specified vertical and horizontal distances from clouds are designed to ensure safe separation and margin for visual navigation.

The other choices present requirements that do not correspond to the regulations established for Class E airspace, thereby making them incorrect. Option B suggests a greater visibility requirement and provides less horizontal clearance, which does not meet the established guidelines. Option C has minimum visibility which is less than required,
