A) If I was fueling a flight in Calgary I would probably get soaked and smell of burnt rhubarb.
They don't de-ice in Calgary while the fuellers are at the aircraft. As WJV04 said, they push the aircraft back a certain distance (supposed to be a plane-length or more, but I've only ever seen a few veterans doing that
) and then de-ice.
1. Air Canada, and im not sure if WestJet does this, but on some aircraft that have stayed the night, and only require a very light de-icing will be pre sprayed at the gate, before or during the boarding process. So that de-icing does not put the aircraft behind sked on a head start flight.
From what I've seen, WestJet does to it to a certain extent, but they most often will use a hot air blower to knock off any light accumulated snow and avoid using any Type I fluid while the aircraft is on-gate.
The blower is also used in combination with their de-ice spray to lower the amount of glycol (Type I) they use on the aircraft and improve coverage when they do the full deicing. WestJet appears to apply Type IV
in the same manner as everyone else.
In my experience, though, even doing a light deicing on-gate isn't really the best option, since the holdover time is usually shot (especially if the temp changes), and the glycol tends to accumulate in the ramp guys' work area and becomes a hazard. That last part is the main reason you're supposed to push back a plane-length or so (not 10-15 feet) off the gate before deicing.... which was common procedure for CP
when I took their training many moons ago.
2. Air Canada propeller Aircraft (Mostly Jazz, and Central Mountain) orginating from the Regional A Wing are usually de-iced at a impromtu taxi through de-ice area set up just south of gate 19 on parking pads 99 through 93.
I've seen Air Canada's deice crews do their aircraft including D8s, A320s and 737s get deiced in a "pad" area off the end of the A wing sometimes, especially when it gets busy or heavy snowfall.
Glycol recovery, is pretty much standard through out the entire airport. Inland has specialized glycol recovery vehicles. Im not sure what Inland does with the glycol once it is recovered. I am also not to sure how other airports deal with glycol. But in my opinion the glycol recovery trucks, as complicated as they look dont do that great of a job. If i were to spray a aircraft one day, and the truck recovers most of the run off glycol, there still will be a residue on the ramp for several weeks.
Hudson General should still have their vehicles around somewhere; they used to do the glycol recovery in YYC
And.... you can't get all the glycol off the ramp due to the consistancy of the stuff, the surface of the ramp itself, and the contaminants the glycol often picks up once it contacts the ramp - oil, hydraulic fluid, gasoline, jet fuel. They do get most of it - enough to keep the Environment Canada people happy.
The stuff is reprocessed and, according to what I was told a long time ago, turned into additives in stuff like radiator fluid for your car and Dr. Pepper.
