Field notes
The form accepts US registration numbers as well as ICAO hex codes, converts locally entered dates to the UTC days used by flight records, and allows multiple ground points with a chosen radius. Its guidance says coordinates remain in the browser tab and recommends barometric altitude when reporting to an airport, tower, or FAA. The free-data window is limited to 45 days, so the page advises users to start saving reports if they need a longer record.
