What condition does "R11L/P3500FT" describe?

The designation "R11L/P3500FT" refers to the specific visibility condition for Runway 11 Left. The "R" indicates that this is a runway report, and "11L" specifies that it is Runway 11 Left. The part "P3500FT" indicates that visibility is greater than 3500 feet.

In aviation weather reports, the prefix "P" is used to denote visibility that exceeds a certain distance. Therefore, in this case, it signifies that the visibility is indeed more than 3500 feet, which is an important piece of information for pilots when assessing landing conditions.

This coding system is standardized in METAR reports to communicate critical information clearly and succinctly, helping pilots make informed decisions regarding takeoff and landing operations based on visibility conditions. Understanding this format enhances comprehension of aviation weather reporting and its implications for flight safety.
