Aircraft Ice Protection is provided by heating of critical areas using Hot Air or Electrical Power sources. Hot Air Heated Area(s): - Outboard half of Slat 2 (Center Slat) and entire length of Slat 3 (Outer Slats) of each wing - Engine Air Intakes (Nose Lip area of each Nacelle Nose Cowling, commonly called the D-Duct Air Inlet Lip area Electrically Heated Area(s): - Fresh Water (Potable Water) and Lavatory “A” Service Panels - Front Windshields (Captain and First Officer) for ice protection, Two Side Windows (Left and Right Sliding and Fixed Windows) for defogging conditions - External Probes, Pitot Tubes and Static Ports - Lavatory “A” Waste Water Forward Drain Mast For Hot Air Heating, the Engine(s) 1 and 2 supply bleed air. APU Bleed Air may be used as an alternate source for Wing Anti-Ice. For Electrical Heating, the electrical power is supplied by AC BUS 1, AC NORM BUS and DC ESS BUS. The Rain Removal System removes rain from the LH and RH Front Windshields that is achieved by windshield wipers. SYSTEM DEACTIVATED at the present time (Heavy rain only, by the Rain Repellent Fluid System.)

Hot Bleed air, supplied by the Engines (Engines 1 and 2) or the APU (Up to 15,000 feet), is ducted in each wing from the fixed leading edge supply duct into the outer slat through a telescopic tube. The Hot Bleed Air is then distributed along this slat by a piccolo tube and also into the Center Slat piccolo tube by a flexible connection across the slats gap. Finally the Hot Bleed Air, after heating the concerned slats, exhausts overboard through vent holes distributed along the slat rear skin. Each wing is equipped with two Anti-Ice Shutoff Valves (Solenoid Controlled and Pneumatically Operated) (NORMAL and ALTERNATE) are arranged in parallel position. • With Engine Bleed Air Supply, only one valve is active, as selected • With APU Bleed Air Supply, both valves are active regardless of mode selection A Flow Limiting Restrictor is fitted down stream of each valve. When WING ANTI ICE SUPPLY is switched ON, a signal is passed to the Pneumatic System which increases the hot air temperature at the Precooler outlet 227 Degrees Celsius (441°F) instead of 177 Degrees Celsius (351°F), and if operating on APU. Bleed Air, the APU Bleed Air flow will be increased. If, during operation, an Anti-Ice Valve fails to OPEN the other valve can be selected for operation. Without Electrical or Pneumatic Supply the valves are springloaded to the CLOSED position. The Wing Anti-Ice Valves will CLOSE automatically if: • Either Engine FIRE Handle is pulled while the AIR BLEED X-FEED valve is CLOSED • The Main Landing Gear Shock Absorbers (Struts) are compressed (Weight on Wheels) On the ground, by the Landing Gear Shock Absorber Torque Links (Weight on Wheels), if the Wing Anti-Ice System is selected ON, overheating of the Slat Number 2 and 3 structure is prevented by means of a Time Delay Relay which limits the Anti-Ice Valve opening time to 10 seconds during the Test Operation of the system..

The valve is normally CLOSED. In the absence of electrical signals, the valve closes through the action of a spring and pressure in Chamber "A". The valve can be locked in the CLOSED position. The valve position (OPEN or CLOSED) is indicated by position indicator switches used for system monitoring. OPERATION When the solenoid is energized, Chamber “A” is vented to ambient pressure at the valve inlet is applied to face “B” of the piston and thus opposes the spring load. The valve OPENS if the Lock Assembly is not actuated. When the solenoid is not energized,, inlet pressure enters Chamber “A”. Pressure in Chamber “A” is applied to face “A” of the piston in addition to the spring load which CLOSES the valve. PNEUMATIC CHARACTERISTICS The valve OPENS at a Minimum Pressure of 10 PSIG. The opening time varies between 0.5 and 5 Seconds, depending on the pressure applied.

Each engine has its own protection system, independent from the Aircraft Pneumatic System. Through an electrically controlled valve for each respective circuit, the Nose Cowl is supplied with hot bleed air from the following: - A300-600/GE CF6-80C2A5F (FADEC)/11TH Stage HP Compressor - A310-200 / GE CF6-80A3 / 10 TH Stage HP Compressor - A31-200/PW JT9D-7R4/15 TH Stage HP Compressor (PS4 Air) Air from the Nose Cowl Leading Edge is exhausted overboard of the Air Intake through a single port at the bottom of the Nose Cowl Assembly. When an Nose Cowl Anti-Ice Valve is OPEN, a signal is passed to the Thrust Control Computer, which decreases the thrust limit relative to ambient conditions, engine operating conditions and anti-ice bleed load. If, while the engine is operating, the electrical power supply, fails, the Nacelle Nose Cowl Anti-Ice Valve OPENS. Each valve is monitored by a Disagree Position Switch.

Valve inlet air pressure is routed through a filter to the reference pressure regulator, passes around the metering valve of the regulator and is sensed on the underside of the regulator diaphragm. When this sensed pressure reaches the desired level, the spring force is overcome and the metering valve moves toward the seat to maintain the reference regulator output pressure at a constant level. Manual override is provided by applying torque to the hexagon shaft and rotating in the desired direction to open or close. When the desired position has been reached, the spring-loaded detent automatically locks the shaft. Visual position indication is provided as well as electrical position indication at the valve open and close positions.

Two window temperature controllers control the windshield temperatures to 35°C/42°C. A temperature sensor in each windshield panel signals the actual. temperature to the related controller, which accordingly activates or deactivates the heating power supply from the control module of the controller to the heating elements of the windshield and side windows. The windshield may be heated on two heating power levels. LOW heating power is used on the ground. HIGH heating power is for In Flight use only. It is inhibited on the Ground. Illumination of two FAULT legends and activation of the ECAM System indicate Window Heat System failure. Devices for testing the Heating Power Supply and the Protection and Warning circuits are provided on the WINDOW HEAT section of the Maintenance Panel 472VU. A Window Heat Protection Unit is installed between the Window Temperature Controller and the windows (Windshield Windows, Sliding and Fixed Side Window ). Each side is provided with one Protection Unit. The unit serves to protect the Window Heat Controller against over voltage due to lightning strikes or to the discharge of electrostatic loads accumulated on the windows to the airframe structure. These induced over voltages pass through the Sensor and/or Power Supply wires and the protection consists in reducing the over voltages on each wire.

To prevent ice formation in or around the drain mast, electrical heating is provided both on the Ground and in the Air (In Flight). The Drain Mast have decals located on each side of the mast to identify the mast is heated and could be HOT (Depending on the System Configuration while in the GROUND MODE) The Drain Mast Circuit Breaker can be pulled to deactivate the mast heating circuit during Ground Parking and/or Maintenance Conditions. The words HOT on each side of the Drain Mast are in Red Color The plumbing system carries waste water from Lavatory “A” Compartment Wash Basin (Sink) to Lower Forward Drain Mast located on 'the outer skin of the aircraft. Lavatory “A” Drain Mast is an electrically heated tube, shrouded by an aerodynamically shaped, cast aluminum fairing. The Heating Element is rated at 285 Watts. On the Ground it is supplied with 28 VAC from an Autotransformer. In Flight 115 VAC is routed to a Rectifier which supplies the heating element with 100 VDC / + 3 VDC. On the Ground the Heating Element can be operated using 115 VAC for a maximum of Five (5) minutes.

Aircraft Ice Protection is provided by heating of critical areas using Hot Air or Electrical Power sources. Hot Air Heated Area(s): - Outboard half of Slat 2 (Center Slat) and entire length of Slat 3 (Outer Slats) of each wing - Engine Air Intakes (Nose Lip area of each Nacelle Nose Cowling, commonly called the D-Duct Air Inlet Lip area Electrically Heated Area(s): - Fresh Water (Potable Water) and Lavatory “A” Service Panels - Front Windshields (Captain and First Officer) for ice protection, Two Side Windows (Left and Right Sliding and Fixed Windows) for defogging conditions - External Probes, Pitot Tubes and Static Ports - Lavatory “A” Waste Water Forward Drain Mast For Hot Air Heating, the Engine(s) 1 and 2 supply bleed air. APU Bleed Air may be used as an alternate source for Wing Anti-Ice. For Electrical Heating, the electrical power is supplied by AC BUS 1, AC NORM BUS and DC ESS BUS. The Rain Removal System removes rain from the LH and RH Front Windshields that is achieved by windshield wipers. SYSTEM DEACTIVATED at the present time (Heavy rain only, by the Rain Repellent Fluid System.)

Hot Bleed air, supplied by the Engines (Engines 1 and 2) or the APU (Up to 15,000 feet), is ducted in each wing from the fixed leading edge supply duct into the outer slat through a telescopic tube. The Hot Bleed Air is then distributed along this slat by a piccolo tube and also into the Center Slat piccolo tube by a flexible connection across the slats gap. Finally the Hot Bleed Air, after heating the concerned slats, exhausts overboard through vent holes distributed along the slat rear skin. Each wing is equipped with two Anti-Ice Shutoff Valves (Solenoid Controlled and Pneumatically Operated) (NORMAL and ALTERNATE) are arranged in parallel position. • With Engine Bleed Air Supply, only one valve is active, as selected • With APU Bleed Air Supply, both valves are active regardless of mode selection A Flow Limiting Restrictor is fitted down stream of each valve. When WING ANTI ICE SUPPLY is switched ON, a signal is passed to the Pneumatic System which increases the hot air temperature at the Precooler outlet 227 Degrees Celsius (441°F) instead of 177 Degrees Celsius (351°F), and if operating on APU. Bleed Air, the APU Bleed Air flow will be increased. If, during operation, an Anti-Ice Valve fails to OPEN the other valve can be selected for operation. Without Electrical or Pneumatic Supply the valves are springloaded to the CLOSED position. The Wing Anti-Ice Valves will CLOSE automatically if: • Either Engine FIRE Handle is pulled while the AIR BLEED X-FEED valve is CLOSED • The Main Landing Gear Shock Absorbers (Struts) are compressed (Weight on Wheels) On the ground, by the Landing Gear Shock Absorber Torque Links (Weight on Wheels), if the Wing Anti-Ice System is selected ON, overheating of the Slat Number 2 and 3 structure is prevented by means of a Time Delay Relay which limits the Anti-Ice Valve opening time to 10 seconds during the Test Operation of the system..

The valve is normally CLOSED. In the absence of electrical signals, the valve closes through the action of a spring and pressure in Chamber "A". The valve can be locked in the CLOSED position. The valve position (OPEN or CLOSED) is indicated by position indicator switches used for system monitoring. OPERATION When the solenoid is energized, Chamber “A” is vented to ambient pressure at the valve inlet is applied to face “B” of the piston and thus opposes the spring load. The valve OPENS if the Lock Assembly is not actuated. When the solenoid is not energized,, inlet pressure enters Chamber “A”. Pressure in Chamber “A” is applied to face “A” of the piston in addition to the spring load which CLOSES the valve. PNEUMATIC CHARACTERISTICS The valve OPENS at a Minimum Pressure of 10 PSIG. The opening time varies between 0.5 and 5 Seconds, depending on the pressure applied.

Each engine has its own protection system, independent from the Aircraft Pneumatic System. Through an electrically controlled valve for each respective circuit, the Nose Cowl is supplied with hot bleed air from the following: - A300-600/GE CF6-80C2A5F (FADEC)/11TH Stage HP Compressor - A310-200 / GE CF6-80A3 / 10 TH Stage HP Compressor - A31-200/PW JT9D-7R4/15 TH Stage HP Compressor (PS4 Air) Air from the Nose Cowl Leading Edge is exhausted overboard of the Air Intake through a single port at the bottom of the Nose Cowl Assembly. When an Nose Cowl Anti-Ice Valve is OPEN, a signal is passed to the Thrust Control Computer, which decreases the thrust limit relative to ambient conditions, engine operating conditions and anti-ice bleed load. If, while the engine is operating, the electrical power supply, fails, the Nacelle Nose Cowl Anti-Ice Valve OPENS. Each valve is monitored by a Disagree Position Switch.

Valve inlet air pressure is routed through a filter to the reference pressure regulator, passes around the metering valve of the regulator and is sensed on the underside of the regulator diaphragm. When this sensed pressure reaches the desired level, the spring force is overcome and the metering valve moves toward the seat to maintain the reference regulator output pressure at a constant level. Manual override is provided by applying torque to the hexagon shaft and rotating in the desired direction to open or close. When the desired position has been reached, the spring-loaded detent automatically locks the shaft. Visual position indication is provided as well as electrical position indication at the valve open and close positions.

Two window temperature controllers control the windshield temperatures to 35°C/42°C. A temperature sensor in each windshield panel signals the actual. temperature to the related controller, which accordingly activates or deactivates the heating power supply from the control module of the controller to the heating elements of the windshield and side windows. The windshield may be heated on two heating power levels. LOW heating power is used on the ground. HIGH heating power is for In Flight use only. It is inhibited on the Ground. Illumination of two FAULT legends and activation of the ECAM System indicate Window Heat System failure. Devices for testing the Heating Power Supply and the Protection and Warning circuits are provided on the WINDOW HEAT section of the Maintenance Panel 472VU. A Window Heat Protection Unit is installed between the Window Temperature Controller and the windows (Windshield Windows, Sliding and Fixed Side Window ). Each side is provided with one Protection Unit. The unit serves to protect the Window Heat Controller against over voltage due to lightning strikes or to the discharge of electrostatic loads accumulated on the windows to the airframe structure. These induced over voltages pass through the Sensor and/or Power Supply wires and the protection consists in reducing the over voltages on each wire.
