Just recently there has been a lot on the news about the fog that has coated Heathrow airport, and that BA has cancelled almost all of their flights. Why have they done this - surely the pilots can use autoland or with the aid of the ils. Also, what affect will this have on the ATC, wouldnt they be able to operate as usual. Finally, why has this only really affected BA. Wouldnt other airlines operating here have just the same problem?
Its only when you look at an ant through a magnifying glass on a sunny that you realise how often they burst into flames
Yes, but LHR is BA's base, and so the majority of traffic in and out of LHR is by BA's aircraft. BD have cancelled some services too, but they don't have as many flights as BA and therefore are affected less.
Again, yes. But because the tower can't see the planes, and the planes can't see each other on the ground, the rate at which th aircraft can take off and land has to be reduced for safety reasons, rather than technological ones. Once the aircraft has landed there is no automated system to help them navigate on the ground and therefore they taxy more slowly.

The problem is not on approach or departure but on the GROUND where autoland means nothing as visual is the key element. So BAA has doubled the MINIMUM aircraft separation in the air to reduce ground (taxiing) congestion and the chances of ground collision.
Since at a MAXIMUM this reduces the number of arrivals and departures by 50 per cent it is a little misleading to say
What is true is that it has affected BA more than any other airline because BA operates more flights from LHR than any other airline and is based there. So for our beloved media they are a much better story than any other airline.

Quoting VV701 (Reply 3): According to BA they are cancelling all their domestic flights and (possibly) some European flights. This is clearly not 'almost all their flights' or, indeed as many as half their flights.
It is also incorrect to say that this
Very true. They've (wisely) cancelled flights where there is the alternative of the train. So domestic flights plus Paris and Brussels. The only reason it has become such a big news story is because people can't get home for Christmas.
Denver airport has also been shut down but you don't see as much fuss about that.

Well during the winter, even DEL airport sees a lot of delays due to fog especially in the domestic sectors since private airlines' pilots aren't trained on the ILS CATIIIB system (only on rwy 28/10). So the airport cannot operate the other rwy (27/9) simulatenously when the RVR drops to about 400m.
However, most international airlines fly in and out just fine with some delays and a lot of airlines change their arrival departure slots to overcome this problem, this has been a persistent problem for delhi airport since the last 4 or 5 years.
There is always chaos at the domestic terminal since there is not enough room to house the passengers who have to wait due to delays but now that the airport has gone to the GMR, some improvements have been made, still however, the major newspapers in India have stories about delays etc. and the not so happy people.
I think during such situations patience really need to become a virtue!!!
