PIREPs
Provides access to PIREPs (Pilot Reports) issued in PIREP or AIREP format — real-time weather observations reported by pilots in flight. PIREPs contain firsthand reports of turbulence, icing, sky conditions, visibility, and other flight conditions at specific altitudes and locations. Unlike METARs (ground-based), PIREPs describe conditions aloft. Report types are UA (routine) or UUA (urgent, indicating severe conditions).
Submitted by pilots reporting actual in-flight conditions including turbulence, icing, and visibility. Provide real-world observations that help other aviators anticipate hazardous weather.
