26、2 Definitions and AbbreviationsRefer to AS6285 Aircraft Ground Deicing/Anti-icing Processes.3. METHODS/PROCEDURES3.1 Inspection of Critical SurfacesOperators should identify for each type of aircraft used in their operations, the critical surfaces which should be checked onpreflight, post deicing/an

27、ti-icing, and pre-takeoff contamination checks. Information from the aircraft manufacturer should be used to determine the critical surfaces for each aircraft type. Examples of this information are available in AS6286/6. Contact the aircraft manufacturer for specific information. The following is a

28、general list of critical surfaces: 3.1.1 Wings, tail, and control surfaces shall be free of frost, snow, slush, or ice. Some coating of frost may be permissible on wing tank lower surfaces cold-soaked by fuel. Ice can build up on aircraft surfaces during flight through dense clouds or precipitation.

29、 When ground OAT at the destination is low, it is possible for flaps and other moveable surfaces to be retracted and for accumulations of ice to remain undetected between stationary and moveable surfaces. It is, therefore, important that these areas are checked prior to departure and any frozen depo

30、sits removed.3.1.2 Pitot heads, static ports, airstream direction detector probes, and angle of attack sensors shall be clear of frost, snow, slush, ice, fluid residues, and protective covers.3.1.3 Engine inlets shall be clear of internal ice and snow, and fan shall be free to rotate. Under freezing

31、 fog, or other freezing precipitation conditions, it is necessary for the front and rear side on the fan blades to be checked for ice buildup prior to start-up. Any deposits discovered are to be removed by directing air from a low flow hot air source or other means recommended by the aircraft and en

32、gine manufacturer. Exceptions will be noted in the Engine Manufacturers Manual.SAE INTERNATIONAL AS6286/1 Page 5 of 393.1.4 Air-conditioning inlets/exits shall be clear of frost, snow, slush, or ice. Outflow valves clear and unobstructed.3.1.5 Landing gear and landing gear doors shall be unobstructe

33、d and clear of frost, snow, slush, or ice.3.1.6 Fuel tank vents shall be clear of frost, snow, slush, or ice.3.1.7 Fuselage shall be clear of ice and snow. In accordance with the aircraft manufacturers manuals, adhering frost may be allowed. Do not close any door until all ice or snow has been remov

34、ed from the surrounding area.3.2 Clear Ice Precautions- Clear ice can form on aircraft surfaces below a layer of snow or slush.- Significant deposits of clear ice can form in the vicinity of the fuel tanks, on wing upper surfaces, as well as under wing.- Aircraft are most vulnerable in regard to thi

35、s type of buildup when one or more of the following conditions exist:a. Wing temperatures remain well below 0 C (32 F) during the turnaround transit.b. Ambient temperatures between -2 C (28 F) and 15 C (59 F) are experienced, although clear ice may form at other temperatures if conditions a, c, and

36、d exist.c. Precipitation occurs while the aircraft is on the ground.d. When frost or ice is present on lower surface of either wing.Clear ice formation is extremely difficult to detect. Therefore, when the above conditions prevail, or when there is otherwise any doubt that clear ice may have formed,

37、 a close examination shall be made prior to departure, in order to ensure that all adhering frozen deposits have in fact been removed.NOTE: Low wing temperatures associated with this type of buildup normally occur when large quantities of cold fuel remain in wing tanks during the turnaround/transit

38、and any subsequent refueling is insufficient to cause a significant increase in fuel temperature.3.3 Flight Crew/Ground Crew Preflight Check RequirementPrior to departure, conduct this check for adhering contamination on critical surfaces.3.4 Deice/Anti-Ice DeterminationDeice aircraft if any frost,

39、snow, slush, or ice is adhering to any critical surfaces.Anti-ice aircraft if there will be active frost or adhering contamination falling or blowing onto any applicable critical surfacesprior to take off.3.5 Initiation of Deicing/Anti-IcingIn the pre-departure sequence, ground deicing/anti-icing ma

40、y be initiated whenever the flight crew or ground personnel determine that deicing/anti-icing is required for safe dispatch. Typically, this would be:- On overnight aircraft, prior to the flight crews arrival.- Following a check by the flight crew and a request for deicing.SAE INTERNATIONAL AS6286/1

41、 Page 6 of 39- After a normal preflight inspection by ground personnel or the flight crew.- After the flight crew is on board the aircraft.3.6 Deice/Anti-Ice LocationDetermine if deicing/anti-icing will be performed at the gate/terminal, off-gate, or at a remote pad. When deicing/anti-icing is perfo

42、rmed away from the gate make sure that the following items are accomplished prior to departing the gate:- All APU and engine inlet/exhaust areas are free of contamination prior to start;- All doors and door seals are free of contamination prior to closing;- Windows are clean and visibility is adequa

43、te from the flight deck, if aircraft will be taxied;- Tires do not appear to be frozen to the ramp;- Passengers are informed if applicable; and- Critical sensing devices are free of contamination.3.7 Communication Prior to Deicing/Anti-IcingWhen the flight crew is onboard the aircraft the ground cre

44、w and flight crew will communicate:- Whether the aircraft needs to be deiced, anti-iced, or both, including fluids to be used,- Engine running considerations- That the aircraft is configured and crews are ready for procedure to begin.In a remote deicing/anti-icing operation, a positive communication

45、 link shall be maintained to the aircraft flight crew throughout the deicing/anti-icing process.Communication to the flight crew may be verbal or by means of Electronic Message Boards or Data Link/ACARS. In the event of conflict, verbal communication shall take precedence.Visual communications (i.e.

46、, Electronic Message Boards or Data Link/ACARS) with flight crew shall occur in the English language.Verbal communications with flight crew should occur in the English language. In states where other native languages are approved for aeronautical verbal communication, these approved native languages

47、 may be used to communicate verbally between ground crew and flight crew upon mutual agreement between both parties. However, services in the English language shall be made available upon request. Personnel who will be communicating with flight crew in the English language shall be proficient in the

48、 English language, familiar with common aviation and de/anti-icing terminology and phraseology, at a minimum level equivalent to an Operational Level 4 on the ICAO Language Proficiency Rating Scale. Additional regulatory authority certification of competency may be required and/or accepted in place

49、of the above-mentioned requirement.3.8 General Deice/Anti-Ice Precautions- The application of deicing/anti-icing fluid shall be in accordance with the requirements of the airframe/engine manufacturers, and local procedures.- With regard to HOT provided by the applied fluid, the objective is that it be equal to or greater than the estimated time from start of anti-icing to start of takeoff based on existing weather conditions.SAE I
