AFAIK 05R/23L has not been used since before Christmas as it hasn't been required. It will be interesting to see if its non-availability this week causes delays if we get any normal weather... Snowing again now....

Which begs the question, whilst the winds have been calm for the past few days why have they persisted in using 05L when they could have been getting some hours on 23R ??
And of course you have been monitoring the 2000 ft winds and visibility too to make an informed decision on which runway to use??......
