A pilot report, or PIREP for short, is when a pilot tells other pilots and air traffic controllers about what kind of weather and flying conditions they are experiencing while up in the sky. It is kind of like a weather report but for airplanes!
When pilots are flying, they can see things that people on the ground cannot see, like clouds, turbulence, and different types of precipitation. They can also feel changes in the wind, temperature, and visibility. By sharing this information with others, they help other pilots make decisions about their flight plans and help air traffic controllers provide safer and more efficient routes.
Pilot reports can be shared in different ways, like over the radio, on a special app or website, or through a special messaging system. They are very important in maintaining safety and efficiency in the sky, and all pilots are encouraged to share them whenever they can.
