What is a recommended visibility standard mentioned for operational safety?

The recommended visibility standard for operational safety is statute mile visibility. This standard helps ensure that pilots can see and avoid potential hazards while navigating through the airspace. It is a key factor in maintaining situational awareness and avoiding collisions. When visibility is measured in statute miles, it provides a clear and consistent metric for pilots to assess their ability to see other aircraft, terrain, and navigational aids in order to operate safely.

In contrast, foggy conditions and cloud cover can significantly reduce visibility, leading to increased risk during flight operations. Clear skies, while conducive to better visibility, are not as practical a standard for operational safety compared to the defined metric of statute mile visibility. This ensures that pilots can operate under a consistent and measurable framework rather than relying on varying conditions such as the absence of clouds or fog.
