Aviation Weather Decoder
Decode realistic training METARs, TAFs, PIREPs, and winds/temperatures aloft forecasts. The balanced 100-challenge deck does not repeat until you have seen every report.

How it works
How the game works
- Each session shuffles a balanced deck of 100 unique METAR, TAF, PIREP, and winds/temperatures aloft challenges without repeats.
- METAR challenges begin at a random point. The shorter TAF, PIREP, and winds/temperatures aloft challenges always begin with the first item.
- There is no deadline. The clock counts upward while quicker correct choices earn more points.
- Only four choices relevant to the highlighted space-delimited coded chunk are shown at a time.
- Wind direction answers randomly use either true degrees or the equivalent compass direction. Nearby compass points are deliberate distractors.
- A wrong choice is marked and you can immediately try another. Mistakes reduce the points available for that term.
- Your 0–1,000 score balances accuracy and speed. Try to beat your best while raising your average.
Your personal best, average score, and the most recent 100 completed rounds are stored only in this browser.
These are generated training reports, not live weather. For flight planning, always obtain current weather from an authorized source. Coding follows the FAA Aviation Weather Handbook and current Aeronautical Information Manual.
There is no time limit. The clock keeps running because quick, accurate selections earn a higher score. The outlined group is the only coded chunk represented in the choice pool. METAR/TAF wind is true, PIREP wind is magnetic, and winds aloft are true.
