I was at YYC (Calgary) earlier for a flight down to LAX. We had about 5cm of snow overnight and I knew that would trigger some form of de-icing routine. For those who have never seen it, a video would be best, but here are some pics which give an idea.
First, most de-icing occurs on areas of the taxi ways away from the gates. This morning, traffic was light and the snow had stopped some hours previously. Therefore the de-icing was pretty relaxed.
This bird had obviously been left out of the garage overnight. De-icing aisle 5!
Actually, most of that is fluffy stuff which I venture is not a huge worry (but has to be removed). So the de-icers move in. Pic on the left has the loose snow being blown off the wing. Note the probes which would alert the operator to contact with the wing in the dark, and when its all steamy. On the right its full on.
Get ready for tail attack .... ATTACK!
They bring in a third unit to supply the coupe de grace. I understand there are 2 basic formulas ... one for 'removal' and a gooier version to stick to the fuselage extra well, to discourage ice build up after take-off. I find the stuff comes in 2 colours .. orange and bright green .. Then we have the bird, nice and shiny and snow and ice free ...
The Air Canada plane below is being de-iced in the off-stand. It took about 10 mins, then there was (as usual) another 5 to 10 min wait. The other pic is the name on a hanger that I bet you all wished you had come up with first
There you have it. On bad nights (ie very snowy / freezing rain) at a busy airport it can be pandemonium. You wait at the gate till your spot in the de icing queue comes up. Taxi over. Wait ages. Get de-iced. Then wait for a departure slot. If too long, go back to get de-iced again. Repeat. Run out of fuel. Go back to gate to re fuel. Go back to de-icing etc etc etc.
Our flight didn't need de icing - it had just flown in and by then it was a nice sunny (albeit very cold) day.
