F900EX EASY 02-30-05 CODDE 1 PAGE 1 / 4 GENERAL INTRODUCTION The ice-protection system is intended to permit safe flight into and through intermittent or continuous maximum icing conditions. The F900EX EASy uses pneumatic and electrical power for its anti-icing and rain protection system. An anti-fogging and demisting system is also provided for the cabin and flight deck windows. Two electrically operated windshield wipers are also provided.

F900EX EASY 02-30-05 CODDE 1 PAGE 3 / 4 GENERAL ANTI-ICING PROTECTION SOURCES The Falcon 900EX EASy is equipped with two anti-icing systems: - one pneumatic system (LH and RH bleed air manifold), - one electrical system using heating resistors. PNEUMATIC SYSTEM SOURCES Engine 1,2,3 and APU bleed air ELECTRICAL SYSTEM SOURCES BUS A1 BUS A2 BUS B1 BUS B2 The pneumatic system, using hot bleed air from the engines, protects the following structural parts and equipment: - inboard / outboard slats, - the fixed leading edge sections on the inboard side of each wing panel, - engines air intake, - engine No 2 S-duct, - brakes (optional), - ECU heat exchanger ram-air inlet. HP air is used for anti-ice protection of engine air intake lips. The electrical anti-ice system protects the following probes, parts and equipment: - LH and RH pitot pressure probes, - LH and RH static pressure probes, - Total Air Temperature (TAT) probe, - Angle Of Attack (AOA) sensors, - stand-by pitot pressure probe, - Pt2 Tt2 sensors (one per engine), - cockpit windshields and windows, - water drains.
02-30-05 F900EX EASY PAGE 4 / 4 CODDE 1 GENERAL ANTI-ICE SYSTEM LOCATION OVERVIEW FIGURE 02-30-05-01 ANTI-ICE AREAS OVERVIEW
F900EX EASY 02-30-10 CODDE 1 PAGE 1 / 8 DESCRIPTION PNEUMATIC ANTI-ICING INTRODUCTION Each engine is fitted with LP and HP bleed air ports located respectively at the LP compressor final stage and HP compressor outlets. The LP and HP air is extracted from the engines through main and auxiliary ports. The main LP bleed ports permanently supply air to the interconnection manifold, named the distribution line to which the main system are connected. When the LP air pressure is not high enough to achieve correct anti-icing or defogging, HP air, extracted through the main HP bleed ports, is injected into the LP bleed air through an electric valve. The Bleed Air System Computer (BASC) controls the electric valve opening and closing. Ice protection of engine air intakes is provided by HP air extracted from the corresponding engine through the auxiliary HP bleed air port. An isolation electric valve (crossbleed valve) can split the distribution assembly into two independent circuits. FIGURE 02-30-10-00 ENGINE BLEED AIR PORTS
02-30-10 F900EX EASY PAGE 2 / 8 CODDE 1 DESCRIPTION DISTRIBUTION FIGURE 02-30-10-01 PNEUMATIC SYSTEM SIMPLIFIED DIAGRAM WITH ANTI-ICE ON The pneumatic system relies on LP and HP bleed air drawn from the three engines. Anti-icing is provided by circulation of LP hot air bled from the last stage of each engine LP compressor. The HP engine bleed air valve located on each engine air bleed regulates the hot air system. A minimum N1 depending on altitude and True Air Temperature (TAT) is necessary to ensure proper anti-icing. When the feeder isolation (crossbleed) valve is closed: - No 2 engine is the only anti-icing supply source for the S-duct, - No 1 and No 3 engines are the only anti-icing supply source for wings.
F900EX EASY 02-30-10 CODDE 1 PAGE 3 / 8 DESCRIPTION ENGINE NACELLE INTAKES The air intake anti-ice systems of all three engines are fully independent. They are supplied with dedicated HP bleed air from the corresponding engine. The HP valve modulates the supply of HP bleed air to maintain a constant pressure in the anti-icing line and limits that pressure. The No 1 engine anti-ice system also provides anti-icing for heat exchanger air intake (engine 1 pylon). No 2 ENGINE S-DUCT Normally, the air supply for the S-duct anti-icing is an HP / LP mix from the bleed-air manifold interconnecting all three engines. However, if the ISOLATION switch on the BLEED AIR panel is closed (stripe vertical), the No 2 engine continues to supply air directly to the bleed air manifold, providing for S-duct anti-icing and cabin air conditioning operation, while engines 1 and 3 supply bleed air for wing anti-icing and cockpit air conditioning. Engine No 2 S-duct FIGURE 02-30-10-02 S-DUCT
02-30-10 F900EX EASY PAGE 4 / 8 CODDE 1 DESCRIPTION WINGS Downstream from anti-icing valve, the hot air system is divided into two lines: - one for RH wing, - one for LH wing. On each wing, the line first supplies the fixed leading edge sections and after the inboard and the outboard slat box structures, through two telescopic tubes. Wings anti-ice protection is mainly ensured by bleed air supplied by No 1 and No 3 engines. The No 2 engine bleed air supply is also available, unless the isolation (crossbleed) valve is closed. The Bleed Air Supply Computer controls and monitors the wings and No 2 engine S-duct anti-ice systems. In AUTO position, the Bleed Air Supply Computer (BASC) controls HP bleed valves to provide correct air pressure in the RH bleed air manifold. BRAKES (option) On each wing line, a pick off in front of the main gear well supplies hot air for the brake unit heating. DEFOGGING AND DEMISTING Air picked off the cockpit air conditioning system helps to remove mist from: - front windshield panel, - pilot panel, - copilot panel, - LH opening window, - LH and RH side windows.

02-30-10 F900EX EASY PAGE 6 / 8 CODDE 1 DESCRIPTION WINDSHIELD AND SIDE WINDOWS The cockpit windows are electrically heated by a network of heating elements incorporated into the transparent panes. The electrical anti-icing system of the windshields is composed of two identical circuits: - one pilot circuit, - one copilot circuit, The pilot and copilot panes are fitted with dual heat regulating sensors, one active and one in stand-by. The heating temperature is automatically regulated between 25 C (77 F) and 30 C (86 F). Pilot windshield Front windshield LH opening window Copilot windshield RH lateral window LH rear window RH rear window FIGURE 02-30-10-04 WINDSHIELD AND SIDE WINDOWS PROBES The pitot pressure probes, static pressure probe, AOA sensors and Outside Air Temperature probe are heated by resistors controlled by switches. Resistors controlled by the PITOT NORMAL pushbutton heat the following probes and sensors: - LH and RH pitot pressure probes, - LH and RH static pressure probes, - LH and RH Angle Of Attack sensors, - Outside Air Temperature probe. Resistors controlled by the PITOT ST-BY pushbutton heats the stand-by pitot pressure probe.
F900EX EASY 02-30-10 CODDE 1 PAGE 7 / 8 DESCRIPTION WATER WASTE DRAIN Drain masts of the water system (one for the forward galley, one for the rear wash basin) are electrically anti-iced. The water drain hoses between rear mast and pressurized area include an electrical resistor which surrounds end fittings. The drain masts and the heating elements of the lines are supplied from the DRAINS HEAT circuit breakers. Drain mast Drain mast FIGURE 02-30-10-05 DRAIN MASTS LOCATION WIPERS Pilot and copilot windshield panes are both equipped with a wiper arm powered by an electrical motor-converter and designed to keep the field of view clear during taxi, take-off, approach and landing phases when raining or snowing. When the wipers are not used, they are stowed in a recess located at the bottom of each windshield. Each wiper is powered and controlled independently of the other by a pushbutton on the LH and RH side of the overhead panel. Maximum speed for wipers operation is 215 kt.
