Anti Ice Panel
The ice protection system allows unrestricted operation of the aircraft in icing conditions.
For anti-icing either hot air or electrical heating protects critical areas of the aircraft.
Hot air is used for the three outboard leading-edge slats of each wing and for the engine air intakes.
Electrical heating is used for the flight compartment windows, the sensors, pitot probes and static ports and for the waste-water drain mast.
