What minimum visibility is required for VFR flight in Class G airspace during the day?

For VFR (Visual Flight Rules) flight in Class G airspace during the day, the minimum visibility requirement is 3 statute miles. This regulation is established to ensure that pilots can maintain visual separation from terrain and other aircraft, promoting safety in less controlled airspace environments.

Visibility of 3 miles allows pilots sufficient sight distance to see and avoid other aircraft, as well as obstacles and the ground, while also enabling them to navigate using visual references. The requirement is designed to support the fundamental principle of VFR flying, which relies on pilots being able to see and interpret the environment around them effectively.

While other visibility options might seem plausible, they do not align with the established regulations for daytime VFR operations in Class G airspace. The 3 statute miles minimum strikes a balance between safety and the practicalities of flying in uncontrolled airspace, providing a reasonable threshold for visual navigation without overburdening pilots with excessive restrictions.
