Ms Lynne Embleton:

I want to reiterate that having a cleared runway is only one part of a solution. If you look at an aircraft and the activity around it, in many cases you have passengers walking to the aircraft and going up the steps. You cannot have ice and keep the customers safe in that environment. There is also a lot of ramp activity around that aircraft, so we need the runway to be clear, but we need the ramp area to be clear as well. In a situation like this the airlines have responsibility and de-icing the aircraft is a key part of our responsibility. The airport has a responsibility too and the two things need to come together to weather these events.
