WHBM..........Maybe I should have been a bit more specific. Gatwick is the worlds busiest SINGLE - USE runway. To say it only has one runway may have been wrong and indeed you are correct in saying they use 26/08R when L is not available but this does not happen all the time now does it.
Also, thank you for supplying the IATA and ICAO cosed for Gatwick however, we were talking about the weather, and I mentioned the single runway bit...Cant see any reference to anybody needing any codes.
Lets say we can be as bad as each other
