Ice and Rain Protection System - General
The Ice and Rain Protection System permits aircraft operation without
restriction caused by icing or heavy rain conditions.
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.)

A300/A310 Wing Anti-Ice System
DESCRIPTION
Ice Protection System for the wings is ensured by heating the leading
edge of the Center Slats (Slat Number 2)(Outboard Half) and the leading
edge of the Outer Slats (Slat Number 3)(Full Length). 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..

Wing Anti-Ice System - Valve Component
DESCRIPTION
The Wing Anti-Ice Valve is a shut off type valve. 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.

A300/A310 Engine Anti-Ice System - Hot Bleed Air Sources
DESCRIPTION
Engine Ice Protection System is .provided by heating of Nose Cowl
Leading Edge (Air Inlet Lip Area) utilizing hot bleed air from the Engine
High Pressure (HP) Compressor. 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.

Nacelle Nose Cowl Air Intake - CF6 Engine Anti-Ice Valve
This is a normally-open valve with solenoid controlled shutoff. 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.

Flight Compartment Window Heat System - General Description
DESCRIPTION
The Flight Compartment Windows are electrically heated; the Front
Windshields for ice protection and defogging, the Side Windows (Sliding
and Fixed) for defogging only.
Two Anti-Ice Regulators (Windshield Heat Temperature Controllers)
control the Front Windshield temperatures to 35°C/42°C. A Temperature
Sensor in each windshield signals the actual temperature to the related
regulator, which accordingly activates or deactivates the heating power
supply from regulator control to the heating elements of Windshield and
Side Windows.
The two Side Windows heat is not temperature controlled.
A Regulator Unit failure results in illuminating the FAULT light on the
WINDOW HEAT Panel 433VU.
Front Windshields are heated on two heating power levels. LOW heating
power is used on the Ground. HIGH heating power is used In Flight.
Window Heat failure warnings are provided by two FAULT indications
and the ECAM Activation.
On the Maintenance Panel 472VU, the WINDOW HEAT Test Panel
provides Controls and Indications for testing the Heating Power Supply
and for testing the Protection and Warning circuits are installed.

Windshield Windows Anti-Icing and Defogging System - Component Operation
DESCRIPTION
The Flight Compartment windows are electrically heated; the windshield
panels for ice protection and defogging, the two Side Windows (Sliding
and Fixed) for defogging only.
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.

Drain Mast Ice Protection
DESCRIPTION AND OPERATION
Waste water from the Lavatory “A” Wash Basin (Sink) is dumped
overboard through the Forward Drain Mast located on the forward belly
area of the fuselage. 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.
