Somehow I smell a rat. And its called money? i had about 9 feet of ice and snow on a Citation wing from the roots out so yes we required deice!
When the truck arrived I was told they had a minimum deployment amount so by the time they finished we had the aircraft dripping tip to tip and nose to tail and about 2/3 more deicing fluid than we wanted or needed with a large bill!
My guess is this regulation is being used to generate work for the deicers! no gripe if its a genuine requirement but sometimes more a genuine requirement for cash in the tills.
