What is the required horizontal cloud clearance in Class G airspace?

In Class G airspace, the regulations specify that for operations below 10,000 feet MSL, a visibility of at least 3 statute miles is required along with a horizontal cloud clearance of 2,000 feet from clouds. This requirement is established to ensure safe separation between aircraft and cloud formations, helping to maintain visibility for pilots flying under visual flight rules (VFR) in uncontrolled airspace.

The other options do not meet the requirements set for cloud clearance in Class G airspace. Specifically, 1,000 feet, 500 feet, and 1,500 feet would not provide the adequate separation needed for safe navigation and operations in such environments. Thus, the correct choice reflects the established safety standards designed to enhance pilot situational awareness and reduce the risk of accidents associated with flying too close to cloud cover.
