3.1 Fluid Types

There are four main times of de-cing and anti-icing fluids used for aircraft: Type 1, 2, 3 and 4. Type 1 fluids have the lowest viscosity are generally used for removing existing ice from an aircraft. Type 2 and 4 fluids include a thickening agent to make them stick to the aircraft to prevent ice from adhering to it. Type 3 fluids have an intermediate thickness between Type 1 and Type 2/4.

Each fluid is characterized by a HOT (Hold Over Time), and a minimum rotation speed. The HOT is the time the fluid will remain effective at preveint

Fluid	Color	HOT (min.)	Min. Rotation Speed
Type 1	RED-ORANGE	n/a	n/a
Type 2	STRAW	0:30	100 Kts
Type 3	YELLOW-GREEN	0:20	60 Kts
Type 4	EMERALD-GREEN	1:00	100 Kts
