What visibility is indicated for KMDW during the reported weather conditions?

The reported visibility for KMDW is stated as 1-1/2 SM, which indicates that pilots can expect to see a distance of one and a half statute miles. This visibility measurement is crucial for pilots as it affects decision-making regarding takeoff, landing, and navigating the airspace.

When visibility is reported, it generally refers to the horizontal distance at which an object can be clearly discerned. The significance of having this specific visibility value is that it directly impacts flight safety and operational capabilities. For instance, certain weather conditions, such as fog or rain, can reduce visibility and could necessitate instrument flight rules (IFR) rather than visual flight rules (VFR).

While other choices represent different visibility values, the specific report of 1-1/2 SM provides pilots with essential information regarding whether they can conduct flight operations safely and what precautions they may need to take if visibility is compromised. Understanding these measurements underscores the importance of accurate weather reporting in aviation.
