What is the minimum flight visibility required for VFR operations on an airway below 10,000 feet MSL?

The minimum flight visibility required for Visual Flight Rules (VFR) operations on an airway below 10,000 feet MSL is established to ensure pilots can see and avoid other aircraft and obstacles. The standard requirement is 3 miles of visibility. This visibility requirement plays a crucial role in maintaining safety during flight, particularly in conditions where visual references may be limited.

Maintaining at least 3 miles of visibility allows a pilot to operate safely and effectively, ensuring that sufficient distance is available to detect and avoid potential traffic and navigate accurately. This distance is essential for operational safety, especially in busy airspaces where multiple aircraft may be present. The regulation is designed to enhance pilot situational awareness and mitigate the risks associated with low-visibility conditions.

In contrast, the other options do not align with the minimum visibility standard set for VFR operations on airways below 10,000 feet, which means they would not provide enough distance for safe operations in such environments.
