Type IV Anti-icing fluid is specifically thickened so as to remain on the wing and other aircraft externals, to prevent ice from forming. Type IV products are not used for ice removal, but rather for icing prevention. Note: Minimum allowed RI for corresponding dilution to meet LOUT requirements. Any dilution higher can be used up to the highest allowed dilution (65/35). Any mixture above 65/35 must not be used. |
