This tool will provide a wind-based analysis of all of the runways at a specified aerodrome. To see the analysis, type the four-letter ICAO code of the aerodrome into the text box and click "Analyse".
The first table will display the recent METAR (weather report) for the aerodrome, with vertical and horizontal visibility extracted.
The second table will display the analysis. The following is a guide on what each column means.
Usability: the appropriateness of a runway will be determined as "yes", "possible", "atc analysis", "disadvantageous" or "no", mainly depending on cross or tail wind components.
Remember that Air Traffic Control always determines the active runway; it is the pilot's job to determine whether it is safe to use the runway(s) depending on the conditions and their aircraft. Where no ATC is present, pilots should use all the information available to them, including the movement of other traffic, to determine the runway which they intend to use.
