Spotted this link on Ringway Reports http://www.manchesterairport.co.uk/web.nsf/Content/RunwayredesignationSo the runways changing to 23/05.Never seen this done before. Is this just happening at Manchester or other airports around the country?

Southampton is now 02/20, I believe it used to be 03/21 a few years back. Incidentally, Southampton used to have three runways!
