• “ICE DETECTED” (amber)–This mes-
sage is displayed when the system de-
tects an ice build-up, the airplane is
airborne, and any of the above listed
anti-icing systems are turned OFF.
• “ICE DETECT FAIL” (amber)–This
message is displayed when the ice de-
tector detects a circuitry fault.
Ice detection advisory and caution messages
(except FAIL) are suppressed during ground
operations through IC-600 logic and the squat
switch system.
VISUAL ICE DETECTION
The airplane is equipped with a wing inspec-
tion light that provides the copilot with the
means to visually detect icing build-up on the
airplane wing during night operations. The
exterior inspection light is turned on by de-
pressing and holding the WING INSP push-
button located on the external LIGHTS control
panel. The light beam illuminates an area of
the outboard right wing, leading edge that has
a black spot affixed to it, to enhance visual de-
tection of ice accumulation.
NOTE
Clear ice on the wing leading edge
may not be detectable from the
cockpit.
ANTI-ICE SYSTEMS
Airplane anti-icing is accomplished through
the use of engine bleed-air and electrical heat-
ing systems to prevent the formation and build-
up of ice on critical areas of the airplane
exterior surfaces. These systems are cockpit
controlled (Figure 10-2) through the ANTI-
ICE control panel, centrally located on the
instrument panel.
Electrically heated systems include the pitot-
static probes, engine inlet air pressure-tem-
