What does a Pilot Report (PIREP) provide?

A Pilot Report, commonly known as a PIREP, is an essential tool in aviation that provides real-time information about the actual weather conditions experienced by pilots during flight. This information is crucial for other pilots and air traffic control, as it helps in making informed decisions regarding flight safety and operational planning. PIREPs can include data on turbulence, icing, visibility, cloud cover, and any other significant weather phenomena that may not be captured in standard weather forecasts or reports.

This type of reporting directly contributes to a better understanding of weather conditions in a particular airspace, enhancing safety for all aviators. Since the PIREP is based on firsthand observations from pilots in flight, it offers specific details that can differ from predicted weather, which is especially valuable for short-term decision-making.
