ENGINE OR WING ANTI-ICE FAILURE (LH OR RH ENG AND/OR LH OR RH WING ANTI-ICE CAUTION LIGHT ON AND MASTER CAUTION)
NOTE
• Indicates engine inlet or wing leading edge temperature is below safe level for satisfactory ice protection. This is normal when engine/wing anti-ice is first actuated, until normal operating temperature is achieved, and if engine speed is reduced below a
IN FLIGHT (STEADY ILLUMINATION)
1. Throttle - INCREASE POWER (Above 70% N2).
2. Engine/Wing Anti-Ice Controls - CHECK SWITCHES AND CIRCUIT BREAKERS.
IF ENGINE ANTI-ICE LIGHT REMAINS ON (AFTER TWO MINUTES)
3. Respective Engine/Anti-Ice Circuit Breaker - PULL.
• Respective WING and ENGINE ANTI-ICE annunciators will be inoperative and the wing/engine anti-ice valves will open. The engine/wing anti-ice switch should remain ENG ON or WING/ENG to operate the pylon inlet heater.
4. Monitor the wing and engine inlet or leave the icing environment as soon as possible.
IF ONLY WING ANTI-ICE LIGHT REMAINS ON
3. Affected Engine/Wing Anti-Ice Switch - ENG ON or WING/ENG.
4. Wing Xflow Switch - WING XFLOW.
IF LIGHT/LIGHTS DO NOT EXTINGUISH OR REILLUMINATE
5. Leave icing environment as soon as possible.
6. After leaving the icing environment, reset circuit breaker (if applicable) and select anti-ice switches OFF.
• If landing in icing environment, use Anti-Ice On procedures.
IF ONLY WING ANTI-ICE LIGHT IS ON AND ENG/WING ANTI-ICE SWITCH IS SELECTED OFF
1. Wing Xflow Switch - WING XFLOW.
2. Respective engine - Reduce power as much as feasible.
3. LAND AS SOON AS PRACTICAL.
• If landing in icing environment, use Anti-Ice On procedures.
