Anti Ice Panel
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
