Thanks for the correction. I was not sure where it was measured from so I noted what I was using.
That leaves GLA 23, which has a displaced threshold, with about 7,500ft. The Boeing tables for landing a fully laden 747 8F in wet conditions require from 8000ft to 8800ft depending on flap setting and how much fuel is left.
Edinburgh has displaced thresholds at both ends so the landing distance is 7500ft from both directions.
