racedo,
Bearcat is quite right that there could be investment to improve the situation. The first requirement is a parallel runway which would allow one to remain in use as the other is cleared. Of course, when this was proposed it was opposed tooth and nail by guess who..oh yes Ryanair. Ryanair didn't need a parallel runway so it shouldn't be built. Major airports like Chicago, JFK, Heathrow, Amsterdam, Brussels and Frankfurt were all closed over the past weeks. They all have multiple runways.They are not short of investment or experience in dealing with adverse weather conditions. If DAA had spent €5m on new equipment in the past year and there was no snow we would be deafened by the howls of protest and condemnation from MOL and his various mouthpieces and such profligate waste. Dealing with adverse weather is not as simple as racedo.
