NORMAL PROCEDURES
BEFORE TAKEOFF CHECK
If icing conditions are anticipated or at the first indication of ice
accretion after takeoff:
1. TKS Ice Protection System. . . . . . . . . . . . . . . . . . . . . . . . . . ON
a. PRIMARY Switch . . . . . . . . . . . . . . . . . . . . . . . . . . . NORM
In order to conserve fluid, the PRIMARY switch may be left
OFF until actual ice can be seen accreting on the airplane.
This is usually first noted on the lower portion of the
windshield. However, to speed the ice shedding, the
PRIMARY switch should then be set to HIGH flow until the
ice has cleared from the wing leading edges. Usually this
will take only three to five minutes. The PRIMARY switch
may then be reset to NORM.
b. MAX FLOW Switch . . . . . . . . . . . . . . . . . . . WINDSHIELD
(press momentarily and repeat if necessary to keep
windshield free of ice)
The ice that forms on the windshield can be cleared
immediately by placing the MAX FLOW switch in the
WINDSHIELD position momentarily. The spray from the
propeller will generally also clear the windshield but will
require a longer period of time.
c. P/S HEAT/LOW A/S AWARE Switch . . . . . . . . . . . . . . . ON
d. STALL HEAT Switch. . . . . . . . . . . . . . . . . . . . . . . . . . . . ON
e. INERTIAL SEPARATOR. . . . . . . . . . . . . . . . . . . . . BYPASS
2. LED PANELS/ANNUN Rheostat. . . . . . . . . . . . . . . . . . ADJUST
(check BELOW ICING MIN SPD light brightness for ambient
conditions)
Do not operate the P/S HEAT/LOW A/S AWARE switch
or STALL HEAT switch for prolonged periods of time on
the ground.
