What flight condition does '10SM' in the METAR report correlate with?

• A. Cloud cover
• B. Visibility range
• C. Temperature variances
• D. Wind chill factor

Answer: (B)

The indication '10SM' in a METAR report refers to visibility range, specifically denoting visibility of ten statute miles. In aviation, visibility is a crucial factor as it affects a pilot's ability to see other aircraft, the runway, and any obstacles. Variability in visibility can arise from weather conditions such as fog, rain, or snow, all of which are important for flight planning and safety. Cloud cover, temperature variances, and wind chill factors are also essential meteorological considerations, but they are represented differently within METAR reports. Cloud cover is reported in terms of the amount of sky obscured by clouds and is often indicated by terms like "FEW," "SCATTERED," or "OVERCAST." Temperature and wind chill are typically found in different parts of the METAR report as well, using specific terminology and units. Therefore, '10SM' specifically and accurately correlates with visibility range.
