According to the news BA is cancelling all domestic services today @ LHR.I find this bewildering as the last actual indicates 100'/600m which is of course well in excess of A319/B757 cat3B minima;I smelleth more BA/LHR pre Christmas chaos redolent of cock-up/mismanagement from the world's favourite -Merry Christmas
Olster, BA are cancelling flights for a number of reasons...one of which is that due to reduced vis, the number of aircraft movements are severly restricted, both on the ground, and in the terminal area. Factor all this in, plus there are airports around that dont have cat 2 or 3 capability..which means you could take off, and have to divert as a matter of course, so what is the point of operating a flight?
