The Message Boards at a Deicing Facility are the display elements of such a system that includes display of aircraft movement monitoring, deicing facility control and records, and possibly deicing truck location and deicing operation performance. The intent of a Message Board di
6、splay at a Deicing Facility is to enhance communication and information to the pilot related to deicing operations. Direct interface with the pilot comprises display of: Aircraft lead-in to the deicing pad bay, Lead-out from the deicing pad bay, and Pertinent de/anti-icing process information. This
7、standard covers the Message Boards for Deicing Facilities. Reference to the overall Central Deicing Facility management system is made to provide an appropriate context. SAE values your input.

36、Start time) 3.2 Purpose: The primary purpose of MBs is to enhance aviation safety by: reducing verbal communication, providing pilots with clear concise information, improving operational efficiency, and reducing congestion by removing personnel and equipment from the deicing area. The MBs shall com
37、ply with applicable FAA/JAA/TC operation regulations and/or standards, and shall provide information to the flight crew regarding any movement/information instruction. 3.3 Technical Requirements: Design, supply and installation of MB shall be in accordance with current regulations, applicable standa
38、rds and generally accepted good engineering practices. SAE AS5635 - 9 - 3.3.1 Design and Selection of Materials: MB parts exposed to the external environment shall be designed to withstand the temperature, pressure, chemical and/or radiation environment associated with deicing/anti-icing conditions.
39、 MB parts exposed to the external environment shall be designed to withstand impact from deicing fluids; and slush and ice particles shed from an airplane and remain functional. Materials shall be of a quality that experience and/or tests have demonstrated to be suitable and dependable. 3.3.2 Workma
40、nship: Workmanship shall be such as to minimize degradation of service performance and reliability. All components shall be fitted properly and firmly in their appropriate positions. All electrical connections shall be mechanically secured and electrically sound. Care shall be given to neatness and
41、thoroughness of soldering, wiring, welding, brazing, surface treatments, painting, screwed and bolted assemblies, marking of parts and assemblies, and elimination of burrs and sharp edges. 3.3.3 Electrical Bonding and Grounding: The MB grounding system shall provide for separation of AC (Alternating
42、 Current) power, DC (Direct Current) power, chassis ground and signal ground(s). On non-conductive enclosures, controls or metal parts that may be touched shall be bonded to ground. Case ground shall not be used for electrical power returns. Materials, surface preparation and finishes for electric b
43、onding surfaces shall be compatible with preservation of adequate electrical conductivity over the life of the Message Board. The maximum resistance across any bonding or grounding junction shall be 1.0 or less, as manufactured. 3.3.4 Manufacturer Identification: Manufacturer identification informat
44、ion shall not be conspicuous on the exterior of MBs. 3.3.5 Operation: Operation of the MBs at deicing facilities shall be consistent with the principles of the procedures required by ARP4902 paragraph 6.4 and ARP4737 Section 10. MBs may be mobile or fixed. 3.4 Facility Considerations: MBs shall cons
45、ider the applicable requirements of ARP4902 Section 4 and paragraphs 4.2.6.5 and 4.3. SAE AS5635 - 10 - 3.4.1 Deicing Pad Layout: Consideration should be given to the following information when locating MBs: Deicing pad layout may involve one or more parallel deicing bays with individual entries fro
46、m the access taxiway and exits to the departure taxi route respectively. A unique identification number distinguishes each bay. Layout may also involve direct entry of aircraft from the entry taxi-way to the deicing bay, or may involve aircraft entry to an area used as a staging bay for hold pending
47、 aircraft transfer to a second bay where deicing is performed. 3.4.2 Pad Lead-In and Exit Identification: MB displays to pilots shall be compatible with Verbal instructions In-ground lighting on the taxiway-to-assigned bay lead-in line, or side-of taxiway indicators may be linked to the message boar
48、d display. Lead-in signage applicable to the bay to be used, only, shall be illuminated so as to provide the approaching aircraft with a unique indication as to which bay to enter. The MB at the assigned bay shall display the aircraft identification/flight number and bay number to provide confirmati
49、on to the pilot. Clear exit instructions, and exit directions will be provided verbally and may be indicated by the message board. 3.4.3 Message Displays: In the event of conflict, verbal communication shall take precedence over visual displays. 3.4.3.1 Aircraft Entry to Pad: (See Figure 1) Verbal entry instructions will be provided. The MB must display pad number, aircraft identification/flight number, and may provide a visual cue to proceed and stop at the red bar. 3.4.3.2 Positioning of Aircraft on the Pad: (See Figure 2) The MB display associated with the a
