What does the acronym PIREP stand for?

The acronym PIREP stands for Pilot Report, and it refers to a vital tool in aviation where pilots provide firsthand accounts of the weather conditions they encounter during flight. PIREPs are crucial for the safety and efficiency of aviation operations as they keep other pilots and air traffic control informed about current weather phenomena, such as turbulence, icing, and visibility.

This real-time data is valuable for adjusting flight paths, making decisions about altitude changes, and preparing for possible weather-related challenges. By sharing their experiences through PIREPs, pilots can aid their peers and contribute to the overall situational awareness of the flying community.
