SAE Type I Fluids (Orange)
25. These fluids in the concentrated form contain a minimum of 80% glycol and are considered "unthickened" because of their relatively low viscosity. These fluids are used for deicing or anti-icing, but provide very limited anti-icing protection.
Note: It is the heat contained by the Type l (de-ice) fluid and the hydraulic forces that removes the frozen contaminants. The glycol provides some protection during precipitation conditions until Type ll, III or IV fluid is applied.
Warning:
Extra vigilance is required by Flight Crews when conducting operations after spraying with Type I fluids only. Flash freeze over (fluid failure) can occur in a very short period of time after the HOT expires, even in very light precipitation conditions. This results in a contaminated critical surface and an unsafe condition for flight.
