While the two runways are being alternately cleared, who, and with what is clearing the taxiways and stands?
Ever tried shifting a heavy jet in thick snow? You think a diversion is expensive? Try having a couple of tugs jack-knife into the fuselage taking the headset men with them! Now that is expensive.
How do you expect the bags/cargo to be offloaded when the stands are thick with snow? Highloaders are not off road vehicles. While were at it, how does an electric buggy pull a set of steps through thick snow?
True, if there was a multitude with shovels and grit you may have a chance but currently forget it.
We do not generally in this country experience the weather we have at the moment. It is not economical to man up and maintain a fleet of equipment that will be used once every other blue moon.
Accept it. It's a bit inconvenient but it's better than injuries to personnel and damaged aircraft.
Don't get me started on de-icing the aircraft!!!!
