What is the minimum flight visibility for VFR-On-Top clearance at 10,500 feet during daylight in Class E airspace?

For VFR-On-Top clearance at 10,500 feet during daylight in Class E airspace, the minimum flight visibility is 5 statute miles. This standard aligns with the regulations outlined in the FAA's aeronautical information. In this scenario, the visibility requirement is complemented by cloud clearance criteria that establish how far a pilot must remain from clouds.

When operating under VFR-On-Top, pilots are granted the ability to fly at a VFR altitude when above a cloud layer, while still adhering to visual flight rules. The requirement of 5 statute miles ensures that pilots maintain a safe distance for visual navigation and avoids conflicts with other air traffic, thereby enhancing safety. This regulation is tailored to mitigate the risks associated with lower visibility scenarios often encountered in cloud cover, ensuring that VFR operations are conducted with adequate situational awareness.

The other choices listed do not meet the established requirements for VFR-On-Top clearance in that airspace and at that altitude, with each of them being either less than the required visibility or not aligned with the specific conditions necessary for VFR-On-Top operations.
