There's quite a comprehensive snow plough actually, think it involves a bit more than a few blokes with brooms too

Yes it's mid winter, yes we get snow in winter, that's why the airport has relocated all of their snow clearing equipment to stand 22, and is why they have been testing the stuff over the past few weeks. However, where do you want them to get staff from when snow starts to fall unexpectedly? Or are you saying they should have 30+ staff sat on their arse all winter on the odd chance snow falls unexpectedly?
I think you need to go and read up on basic economics of running an airport, or operating any business for that matter.
