Why don't they de-ice planes like a car wash?

Question:
Why don't airports de-ice planes right before take off (at the end of the runway).

What steps should I take, at the scene, if I'm in a car accident?

Have a large setup at the end of the taxiway where each plane gets de-iced second before they get on the runway for departure?

Answers:

Can you occupy a camper trailer while towing it? If not, do any states allow it?

That's one way that it's actually done. Many airports do it exactly that way, especially in severe icing conditions.

What exactly does it mean at the gas station when they say "do not top off"?

The don't use a building like a carwash to do it, they use bucket trucks or cherry pickers but the de-icing operation is done right on the hammer-head immediately prior to departure.

Road bullies?

It's not possible to erect a structure that close to the runway for safety reasons, but it's easy to do it with portable deicing equipment.

Can the human eye cause accidents due to misconceptions?

Interesting proposal but three problems come to mind. First, the structure they would have to build would be massive and the pilots would be "driving" through it very fast - lots of danger of "clipping off a wing" if you are off by a little bit. Two, Planes are going at around a hundred miles an hour when they take off, the air rushing by decreases the temperature even more on the wing surface - bad if you are trying to deice. Third and most important. the ice needs to be off the plane before the plane starts to take off. This is because ice is very heavy and the buildup of ice adds "size" (area) to the wings. The additional weight on the plane and area on the wing means more drag which hurts the ability of the plane to takeoff.

Why do people feel the need to endanger others by multitasking while driving?

A car-wash type system for airplanes would have to be huge to accommodate the large commercial jets in service today, but would also waste a lot of the deicer fluid, from overspray and from excessive application.

Do NY school buses have to have those cross arms that extend to keep kids out of the driver's blind spot?

A human operator directing a stream of heated deicing fluid at the effected parts of the aircraft is a much more efficient way to insure the aircraft is clear of ice and safe to take-off.
