R R R R - the APU air intake, - the ram air inlets, - the landing gear doors, - the engine cowls and air intakes, - the outflow valve air outlet, - the pitot probes, - the static probes, - the AOA sensors.
(2) Do not put too much de-icing fluid in the rudder, elevator and aileron servo-control areas. Use sufficient fluid to remove the snow.
R R R NOTE : If the layer of snow is too thick, remove most of the snow____ with brooms. (Use brooms with soft bristles so that you do not cause damage to the skin of the aircraft).
R R R R R (3) To prevent the flow of fluid on the cockpit windows, remove the remaining ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-001), ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-003) or ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-004) from the forward areas. You can clean the surface with clear water and a soft cloth.
R R R R (4) If you find ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-001), ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-003) or ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-004) on the cockpit or cabin windows, clean the window with clear water and a soft cloth.
R NOTE : Do not use the wipers to clean the fluid on the windows.____
R R R NOTE : If you use ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-____ 003), make sure that there is no remaining fluid on the cockpit windows. Be specially careful of windows with wipers.

____________________________________________
TASK 12-31-12-660-002
De-icing of the Aircraft Parked in an Open Area (Engines Stopped)
WARNING : DO NOT APPLY ANTI-ICING FLUID IN:
_______
-
THE AIR INTAKES AND EXHAUST OF THE ENGINES OR APU
-
THE AIR OUTLET OF THE OUTFLOW VALVE 10HL
-ALL OTHER AIR INTAKES OR OUTLETS.
CAUTION : DO NOT POINT HIGH-PRESSURE JETS:
_______
-
AT EQUIPMENT SUCH AS GEAR BOX SEALS, STEADY BEARINGS, ROTARY ACTUATORS AND UNIVERSAL JOINTS,
-
AT ELECTRICAL COMPONENTS SUCH AS HARNESSES, PROXIMITY SENSORS AND
CONNECTORS.
THE IMPACT PRESSURE OF THE JETS MUST NOT BE MORE THAN 5 PSI (0.35
BAR). FOR FAIRINGS, THE IMPACT PRESSURE OF THE JETS MUST NOT BE MORE
THAN 1.5 PSI (0.1 BAR).
HIGH PRESSURE JETS CAN PUSH LIQUIDS INTO BEARINGS, JOINTS, BRAKES,
ELECTRICAL CONNECTORS AND OTHER SEALED COMPONENTS. LIQUIDS THAT GET
INTO THESE AREAS CAN CAUSE CORROSION, FREEZE DURING AIRCRAFT FLIGHT,
REMOVE NECESSARY LUBRICANTS OR START INCORRECT ELECTRICAL FUNCTIONS.
CAUTION : DO NOT USE JET EXHAUST TO REMOVE SNOW OR ICE FROM THE AIRFRAME. THE
_______ HIGH PRESSURE AND HIGH TEMPERATURE OF JET EXHAUST CAN CAUSE DAMAGE TO THE AIRCRAFT.

R NOTE : These guidelines have been prepared using the Association of European
____ R Airlines (AEA) recommendations : Recommendations for the de-icing of aircraft on ground.
NOTE : The operators must use the procedures applicable to their individual
____
operating methods and requirements.
NOTE : The data given in the tables in this procedure are guidelines only.
____ The user can use these guidelines and his experience and knowledge of the local weather conditions to help him make the decision. It is the responsibility of the user to make the decision about the applicable methods of protection. the time of protection will be shorter in very bad weather conditions. High wind speeds and jet blast can cause damage to the protective film. if these conditions occurs, the time of protection will be much shorter.
The time of protection can also be much shorter if the wing
temperature is lower than the OAT.
Because conditions are not always the same, a pre-take-off inspection
is necessary when you use the times given in the tables.
The procedures show how to remove ice and snow from some areas of the aircraft when the engines are stopped. 中國航空網(wǎng) www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320飛機維護手冊 AMM SERVICING 2(48)
