What is a PIREP?

A PIREP, which stands for Pilot Report, is a valuable tool in aviation as it provides real-time weather information directly from pilots in flight. This information can include observations about turbulence, cloud cover, visibility, and other atmospheric conditions encountered during the flight. PIREPs are critical for enhancing situational awareness for other pilots and for air traffic control, allowing them to make informed decisions regarding flight operations and route planning.

The details provided in PIREPs can help pilots anticipate weather conditions on their routes, potentially leading to safer flight operations. Given that this real-time input comes directly from those flying the aircraft, it plays an essential role in maintaining safety standards and improving the overall efficiency of flight operations.
