Visibility of 1 1/2 statute miles is considered what in aviation terms?

In aviation terminology, visibility of 1 1/2 statute miles is classified as moderate visibility. This classification is important because it plays a critical role in flight operations, affecting both visual flight rules (VFR) and instrument flight rules (IFR).

Moderate visibility indicates that while pilots can generally see and navigate, conditions may not be optimal, especially for those relying heavily on visual references. It suggests that pilots may encounter some limitations in seeing distant objects clearly, which could impact their ability to perform certain maneuvers safely. Therefore, while it is not the worst visibility condition, it is important for pilots to exercise caution and remain aware of their surroundings when operating under these visibility conditions.
