A PIREP is a report of meteorological phenomena that is

• A. Reportable on the weather observation
• B. Encountered by aircraft in flight
• C. Of importance to the controller
• D. Of importance to the pilot

Answer: (B)

PIREP is a pilot report describing weather phenomena encountered during flight. It comes from what a cockpit crew experiences in the air, not from surface observations or forecasts. This in-flight, in-situ report helps other pilots and meteorologists anticipate conditions ahead, such as turbulence, icing, or wind shear. While controllers may use PIREPs, the defining point is that the information is about phenomena encountered by an aircraft in flight, not just a general weather observation or a report primarily for the controller.
