What are the minimum visibility requirements for VFR flight?

The minimum visibility requirements for Visual Flight Rules (VFR) operations are established to ensure pilots can navigate safely and avoid collisions with other aircraft and obstacles. Under VFR, pilots must be able to see and avoid other traffic, as well as maintain visual reference to the ground.

The correct answer of three statute miles is the minimum visibility requirement in Class C, D, and E airspace below 10,000 feet MSL for daytime VFR operations. This distance allows pilots to have a clear line of sight to conduct their flight safely, ensuring they can react to both airborne and ground hazards. The requirements can vary slightly depending on the airspace classification and the altitude, but three statute miles is a common standard in many VFR scenarios. Thus, it provides a balance between safety and flying efficiency, allowing pilots to maintain a visual reference necessary for navigation.
