What does a PIREP stand for in aviation weather reporting?

A PIREP, or Pilot Inflight Report, is an important component of aviation weather reporting. It represents real-time observation and information provided by pilots regarding weather conditions during flight. This can include details about turbulence, cloud cover, visibility, wind conditions, and other atmospheric phenomena that may affect safety and operational decisions.

Pilots submit PIREPs when they encounter significant weather conditions that are of interest to other pilots and air traffic control; thus, they significantly contribute to the current understanding of weather dynamics in the airspace.

The accuracy and relevance of PIREPs are crucial as they provide a firsthand assessment of conditions in-flight, aiding in the timely dissemination of weather information to enhance safety and efficiency in aviation operations.
