Ensure all anti-ice fluid has been removed from graduated cylinder
prior to testing the next collection point.
(g) When Pump#1 Ground Flow Test is complete, set System Switch to OFF. (See Figure 3)
(h) Measure and record ambient temperature of area where Pump#2 Ground Flow Test is
being performed.
CAUTION: Avoid subjecting aircraft to localized areas of elevated temperatures (high
intensity lights, area heaters, etc.) as temperature gradient will introduce
inaccuracy in measurements.
(i) Set PUMP BKUP switch to ON. (See Figure 3)
(j) Observe voltage of Pump#2 and adjust its operating voltage to 27.10 VDC nominal via
ground power supply.
(k) Record operating voltage of Pump#2.
CAUTION: Ensure supplied voltage of ground power supply does not drift in excess of
±0.02 VDC during test.
(l) Repeat Ground Flow Test while operating system with Pump#2.
Note: The time necessary for system to stabilize will be dramatically reduced if
Pump#2 test is repeated directly after Pump#1 test.
(m) When Pump#2 Ground Flow Test is complete, set PUMP BKUP switch to OFF. (See Figure
3)
(n) Perform Procedure - System Acceptance Criteria. (Refer to Section L.)

J. Procedure - Ground Flow Test #2
(1) Acquire necessary tools, equipment, and supplies.
(2) Prepare test fluid.
WARNING: Due to differing freezing point depressant properties, do not use test fluid in
place of anti-ice fluid for airborne operation of the FIKI ice protection system.
CAUTION: Mix test fluid at same temperature as ambient conditions of ground flow test as
viscosity of test fluid is inversely related to its temperature. (For example, increasing
temperature of fluid decreases its viscosity.)
All test fluids must be filtered to remove particulates larger than 0.6 microns prior
to entering the aircraft to ensure that it is acceptably free from contaminants.
When switching between fluids, TKS cart and all containers must be emptied and
cleaned prior to use. Discard any fluid that has been, or is suspected of being a
mixture of test fluid and anti-ice fluid. Typically a combination of the fluids will
show signs of "streaks" when one has been introduced into the other.
(a) Using clean, empty container, begin test fluid mixture with a 3:1 ratio of Glycerin to De-ionized
water or 1:2 ratio of Glycerin to Propylene Glycol.
(b) Perform Test Fluid Mixing:
1 Perform Procedure - Measure Kinematic Viscosity. (Refer to Section K.)
Note: Glycerin must be "thinned" using Propylene Glycol and/or De-ionized
water to reach desired viscosity in any proportion necessary. (See
Figure 4)
Viscosity of 63 is desired for test fluid mixture. However, it is acceptable
for fluid to vary between 53 cSt (anti-ice fluid @ -10°C) and 75
cSt (anti-ice fluid @ -15°C).
2 If less viscosity is required, add small amount of Propylene Glycol and/or De-ionized
water.
3 If more viscosity is required, add small amount of Glycerin.
(c) Repeat Test Fluid Mixing until desired viscosity reached.
(3) Replace anti-ice fluid in system with test fluid.
(a) Drain anti-ice fluid from both glycol tanks on aircraft. (Refer to AMM 12-10)
(b) Fill both glycol tanks on aircraft with test fluid. (Refer to AMM 12-10)
(c) Drain anti-ice fluid from pressure tank on TKS cart.
(d) Fill pressure tank on TKS cart ¾ full with test fluid and replace access lid.
Description P/N or Spec. Supplier Purpose
Glycerin, 99.5% USP min. - Any Source Test fluid component
(increases viscosity).
Propylene Glycol, 99.5% USP min. - Any Source Test fluid component
(decreases viscosity).
De-ionized (distilled) water

Note: Ensure access lid gasket is in place.
(e) Set System Mode switch to HIGH, and activate Pump#1 by setting System Switch to ON.
(See Figure 3)
Note: If desired, Pump#2 can be activated to increase flow rate of system by also
setting PUMP BKUP switch to ON. This will cause system to run in a "continuous"
MAX, as opposed to standard 2 minute cycle achieved by pressing
MAX Mode button.
(f) Operate system until there is evidence of test fluid at all collection locations.
Note: Test fluid will have an "oily" odor as opposed to alcohol of anti-ice fluid, and
