additive in the fuel. When an anti-icing additive is used it must
meet the specification MIL-1-27686. must be uniformly blended
with the fuel while refueling. must not exceed .15% by volume of
the refueled quantity. and to ensure its effectiveness should be
blended at not less than .10% by volume. One and one half liquid
ounces per ten gallons of fuel would fall within this range. A blender
supplied by the additive manufacturer should be used. Except for
the information contained in this section. the manufacturer's
mixing or blending instructions should be carefully followed.
CAUTIONS
Assure that the additive is directed into the
flowing fuel stream. The additive flow should
start after and stop before the fuel flow. Do not
permit the concentrated additive to come in
contact with the aircraft painted surfaces or the
interior surfaces of the fuel tanks.
Some fuels have anti-icing additives pre-
blended in the fuel at the refinery, so no further
blending should be performed.
