What does the abbreviation "RWY" stand for in a METAR report?

The abbreviation "RWY" in a METAR report stands for "Runway." In aviation terminology, the runway is the specific area of an airport designated for the landing and takeoff of aircraft. METAR reports provide crucial information for pilots regarding current weather conditions at an airport, but they also include vital data that relates to the physical infrastructure, such as runways.

Understanding the different elements in a METAR report is essential for pilots and air traffic control, as they must be aware of which runways are in use, their conditions, and any operational notices that may affect them. This knowledge helps ensure safe operations at airports, particularly in various weather conditions and during high-traffic situations.

The other options, while they represent other aviation-related terms, do not accurately describe what "RWY" indicates within the context of a METAR report. "Weather," "Regional," and "Radar" are unrelated to the specific reference to airport runways.
