How does the night VFR visibility requirement in Class G airspace differ from daytime?

In Class G airspace during night VFR operations, the visibility requirement mandates a minimum of 3 statute miles visibility, along with specific cloud clearance criteria. This is in contrast to daytime operations in Class G airspace, where only 1 statute mile visibility is required.

The rationale behind this difference is primarily to ensure that pilots have a sufficient visual reference to navigate safely in lower light conditions. Greater visibility and cloud clearance are crucial during nighttime when natural visual cues are diminished. The specified cloud clearance requirements help to integrate safe flying practices regarding aircraft separation and enhance the pilot's ability to see and avoid obstacles, such as terrain and other aircraft.

By requiring 3 statute miles of visibility along with the specified cloud clearance, the regulations aim to promote safer flight operations in the more challenging conditions presented by nighttime flying.
