If visibility is reported as "1 1⁄2SM," how many statute miles of visibility is this?

The visibility reported as "1 1⁄2SM" translates directly to 1.5 statute miles. This notation is a common way to express measurements in aviation, where "SM" stands for statute miles. The fraction "1 1⁄2" represents one and one-half, which is equivalent to 1.5. This understanding of fractional representations is crucial for interpreting weather reports accurately, especially in contexts like aviation where visibility is a critical factor for safe operations. Knowing how to convert such expressions is important for remote pilots to make informed decisions during flight. This clarity in translating visibility measurements helps ensure safety in operations where visual flight rules (VFR) apply.
