What are the basic VFR weather minimums for flight at 6,500 feet MSL according to the regulations?

The basic VFR (Visual Flight Rules) weather minimums for flight at 6,500 feet MSL (Mean Sea Level) are primarily concerned with visibility and cloud clearance requirements that allow pilots to operate under visual flight rules. According to the regulations, a pilot must maintain clear visibility and avoid clouds to safely navigate and control the aircraft.

The correct answer states that a pilot must be clear of clouds and have at least three statute miles of visibility. This requirement helps ensure that pilots can see and avoid other aircraft, terrain, and obstacles, thereby enhancing safety during flight. Staying clear of clouds also allows a pilot to maintain visual reference to the ground or other prominent landmarks, which is essential for navigation and situational awareness while flying under VFR conditions.

In contrast, the other options do not comply with the established VFR minimums at the specified altitude. For example, maintaining cloud clearance is important, but the requirement must be met along with visibility conditions, making simply being below a certain cloud level insufficient. The mention of "none apply due to positive radar control" is irrelevant as VFR minimums are a separate regulation that must be adhered to regardless of radar coverage. Lastly, visibility less than five statute miles does not meet the minimum requirement,
