Definition
Standardized observations of current weather conditions used by pilots for flight planning and in-flight decision making. The primary aviation weather reports include METARs (routine surface observations at airports), PIREPs (reports from pilots already in flight), and Radar Weather Reports (which show precipitation patterns and intensity). Each report follows a fixed format and coded structure so the information can be read quickly and consistently by any pilot or controller.
Plain English
These are official reports describing weather that has actually been observed — at airports, by pilots in the air, or by weather radar. They are written in a standard short-form code so any pilot can read them the same way and get a quick, accurate picture of what the weather is doing right now.
Context Anchor
Seen during preflight planning, weather briefings, and in-flight weather updates when a pilot checks the latest conditions along a route or at an airport.
Derivation
Report comes from a Latin idea meaning “to carry back.” That fits this term because a weather report carries observed weather information back to the people who need it for a flight.
Why Pilots Care
They supply the precise data needed to judge whether conditions support safe takeoff, flight, and landing.
Grounding Statement
An aviation weather report is a snapshot of observed weather at a place and time that matters to a flight.
Intuition Check
Do not read “report” as the same thing as “forecast.” A report describes observed weather; a forecast predicts what the weather is expected to do later.
Example Sentence 1
Before departure, the pilot reviewed the aviation weather reports for the destination and en route airports to confirm conditions were suitable for VFR flight.
Example Sentence 2
Checking aviation weather reports at the destination airport showed improving visibility after the front passed.
