Anti Ice Panel
API Documentation: ANTI ICE Panel API
Description
The ice protection system allows unrestricted operation of the aircraft in icing conditions.
This system protects the critical areas of the aircraft against ice, by using:
- Hot bleed air for:
- Engine anti-ice
- Wing anti-ice
- Electrical power for:
- Window heating
- Water/Waste drain masts heating
- Probe heating
An ice detection system measures ice accretion via the anti-ice control system and provides this information to the flight crew.
Usage
WING anti-ice
- OFF:
- Wing anti-ice is off.
- ON:
- Wing anti-ice is on.
- The ECAM displays the WING A-ICE memo.
- On ground, the wing anti-ice valves will open for 30s. Wing anti-ice will then be inhibited for 10 min, provided the aircraft is not in flight. If the flight crew does not switch off the wing anti-ice, the ON light will remain on, even though the wing anti-ice valves are closed. The wing anti-ice valves will then reopen after takeoff thrust reduction.
- FAULT:
- The wing anti-ice valve position disagrees with the requested position
- Or, the wing anti-ice valve is open, but a low pressure is detected.
- Amber light and ECAM caution message.
- The FAULT light goes off, when the affected wing anti-ice system is recovered, after applying the appropriate procedure.
- If the system cannot be recovered, the FAULT light will remain on for the remainder of the flight.
ENG 1+2+3+4
