What does a Pilot's Report (PIREP) include?

A Pilot's Report, commonly known as a PIREP, is a valuable source of real-time information regarding weather conditions observed during a flight. It is primarily used by pilots to communicate their experiences and findings related to atmospheric phenomena, which can include cloud conditions, turbulence, wind shear, temperature variations, and visibility at various altitudes.

This information is essential for other pilots and air traffic control because it helps in assessing current weather conditions that might not be reflected in official forecasts or reports. Ground personnel, meteorologists, and other aviation stakeholders use these reports to make informed decisions regarding air traffic management and safety.

The other options, while related to the aviation field, do not accurately reflect the primary content of a PIREP. Responses to flight safety surveys, pre-flight weather assessments, and emergency weather updates serve different purposes within aviation operations and do not directly involve the pilot's firsthand observational reporting during a flight.
