Quite the Deicing Force.....

Nice pic CYYC

How long does deicing process last during freezing temps before departure? Say you've deiced, left the gate and are waiting in line for an hour for your turn to take-off and it's been over an hour. Isn't there an FAA time-limit rule you must return to the terminal for re-deicing after an hour?

Love that M.D.-11

When I was flying for FedEx, it was 22-25 min depending on weather. Obviously, weather and rain play a factor.

Diana, there are different times depending upon which de-icing fluid is used and temperature conditions.

Many airports have adopted the safety recommendation to have de-icing booths closer to the runways. After a few accidents, investigators pointed out the problem of de-icing at the gates and then the length of time it could take to get to takeoff. So many cold weather airports setup de-icing operations closer to the runways. They are almost like running your car through an express car wash.
