Weather Delays
I am writing up a report for university about my work placement for an airline at Heathrow and am writing a section about delays to airlines. Anyway I have included a small section about human factors in delays. I am discussing human factors in weather delays (if there are any) I am saying that there are as aircraft can take off in most types of weather, but for instance if there is fog at EGLL the amount of movements is restricted because they can't be seen from the tower by ATCOs. I am mainly talking about ground movements. I know that landing separation has to be increased to protect the ILS etc so that restricts the flow.
The question I am asking is have I got a valid point or am I completely off the mark. I would be grateful if any ATCOs would be able to let me know. Thanks
