The ice lights illuminate the leading edge of
both wings for visual inspection at night. These
ice lights are controlled by the ICE/LOGO
switch in the roof panel EXTERIOR LIGHTS
group. Power for the wing inspection lamps is
from the PS1 bus bar.
The ice warning annunciators are powered
from the PS2 bus bar.
AIRFRAME ANTI-ICING
SYSTEM
DESCRIPTION
TKS R328 or TKS 80 is used for anti-icing the
leading edges of the wings and horizontal sta-
bilizer (Figure 10-4). A single WING/TAIL
ANTICE time switch on the roof panel ICE
PROTECTION group controls this system.
The TKS fluid is stored in a tank which holds
10.0 U.S. gallons. This quantity provides fluid
for priming and protection for approximately
108 minutes. The tank filler cap is accessible
from inside the cabin forward of the main
entry door or behind the pilot’s seat (Figure
10-5). The FULL/EMPTY indicator is located
on the copilot’s side console and reads FULL
at 8.25 U.S. gallons and EMPTY when there
is still 12 minutes’ protection available.
Other airframe anti-icing components are the
DC motor-driven metering pump mounted ad-
jacent to the tank, a filter, a compensating valve,
wing and tail proportioning units, and wing
and tail distribution panels (Figure 10-4).
OPERATION
Before flight, the system should be primed
when power is on the airplane. Set the
WING/TAIL ANTICE time switch to run
