Again, for us at YVR, as my colleague Philippe said, it depends on the conditions, but certainly the conditions that we saw, with the accumulation of snow in such a short period of time and the density of it, meant that the time out period maximums were exceeded, so by the time you've de-iced the aircraft efficiently, got it to the airfield, it has exceeded the maximum time that regulations allow for the aircraft to safely depart and it has to go back to de-icing and start that process all over again, so it depends on the weather conditions and the maximum time out thresholds.
