There are several types of de-ice and anti-icing fluids. What you saw was Type
1 fluid being applied, followed by an application of Type 4 fluid.
Type 1 is the reddish orange fluid It is a very thin fluid that is heated and
applied to de-ice the aircraft.
To prevent ice from reforming, Type 4 fluid is applied. Type 4 is the emerald
green fluid that is not heated. Type 4 is a thicker fluid and can be used on
aircraft that have a rotate speed greater that 80 to 100 knots. Aircraft with
slower rotate speeds would not generate the necessary energy to shear and
eliminate the fluid from the aircraft prior to take-off.
The cost of de-icing an aircraft varies greatly. The variances include the cost
of the fluid, the weather conditions, and the pilot's request (wings and stab
only or entire aircraft).
I have been charged as little as $250.00 US dollars in Kansas to a whopping
$10,000 CA dollars in Montreal.
