(800) 767.9989 or telnet://direct.duats.com For customer service: (800) 345.3828 Data Transformation Corporation (DTC) 108.D Greentree Road Turnersville, NJ 08012 Internet Access: http://www.duat.com For customer service: (800)243.3828 d. Inflight weather information is available from any FSS within radio range. The common frequency for all AFSSs is 122.2. Discrete frequencies for individual stations are listed in the A/FD. 1. Information on In-Flight Weather broadcasts. REFERENCE. AIM, Inflight Weather Broadcasts, Paragraph 7.1.10. 2. En Route Flight Advisory Service (EFAS) is provided to serve the nonroutine weather needs of pilots in flight. REFERENCE. AIM, En Route Flight Advisory Service (EFAS), Paragraph 7.1.5, gives details on this service. 7.1.3. Use of Aviation Weather Products a.Air carriers and operators certificated under the provisions of 14 CFR Part 119 are required to use the aeronautical weather information systems defined in the Operations Specifications issued to that certifi-cate holder by the FAA. These systems may utilize basic FAA/National Weather Service (NWS) weather services, contractor. or operator.proprietary weath-er services and/or Enhanced Weather Information System (EWINS) when approved in the Operations Specifications. As an integral part of this system approval, the procedures for collecting, producing and disseminating aeronautical weather information, as well as the crew member and dispatcher training to support the use of system weather products, must be accepted or approved. b.Operators not certificated under the provisions of 14 CFR Part 119 are encouraged to use FAA/NWS products through Flight Service Stations, Direct User Access Terminal System (DUATS), and/or Flight Information Services Data Link (FISDL). c.The suite of available aviation weather product types is expanding, with the development of new sensor systems, algorithms and forecast models. The FAA and NWS, supported by the National Center for Atmospheric Research and the Forecast Systems Laboratory, develop and implement new aviation weather product types through a comprehensive process known as the Aviation Weather Technology Transfer process. This process ensures that user needs and technical readiness requirements are met before experimental products mature to operational application. d.The FAA, in conjunction with the NWS, established the Aviation Weather Technology Transfer (AWTT) Board so that newly developed aviation weather products meet regulatory requirements and enhance safety. The AWTT is charged with managing and accelerating the transfer of these products into operational use. Members of the AWTT Board include mid.level managers from the FAA and NWS who are responsible for various Meteorology 7.1.3 aspects of the development and use of aviation weather products (e.g., aviation weather R & D, transition of weather products from R & D to operational use, etc.). e.The AWTT is a management.review and decision.making process that applies criteria to weather products at various development stages (decision stages, i.e., “D.stages”). The D.stages are composed of the following: 1.(D1) Sponsorship of user needs. 2.(D2) R & D and controlled testing. 3.(D3) Experimental application. 4.(D4) Operational application. f.Weather products maturing into the D3 experimental stage of the AWTT process are often made available to the public on the Aviation Weather Center’s Experimental Aviation Digital Data Service (ADDS) website at: http://weather.aero/. The intent is to allow public access to this information in order to obtain feedback for product development and improvement. However, it is important to note that weather products displayed on this site are experimental, and although they may appear to be fully operational products, they are subject to change without notification and may not be used for any flight related decisions. At the D4 stage, the FAA approves a weather product for operational use by end users (with restrictions, if necessary), and the product is made available to the public via long.line circuit, satellite, and/or other means of communication. g.Pilots and operators should be aware that weather services provided by entities other than FAA, NWS or their contractors (such as the DUATS and FISDL providers) may not meet FAA/NWS quality control standards. Hence, operators and pilots contemplating using such services should request and/or review an appropriate description of services and provider disclosure. This should include, but is not limited to, the type of weather product (e.g., current weather or forecast weather), the currency of the product (i.e., product issue and valid times), and the relevance of the product. Pilots and operators should be cautious when using unfamiliar products, or products not supported by FAA/NWS technical specifications. NOTE. When in doubt, consult with a FAA Flight Service Station Specialist. h. In addition, pilots and operators should be aware there are weather services and products available from government organizations beyond the scope of the AWTT process mentioned earlier in this section. For example, governmental agencies such as the NWS, the Aviation Weather Center (AWC), and the National Center for Atmospheric Research (NCAR) display weather “model data” and “experimental” products which require training and/or expertise to properly interpret and use. These products are developmental prototypes that are subject to ongoing research and can change without notice. Therefore, some data on display by government organizations, or government data on display by independent organizations may be unsuitable for flight planning purposes. Operators and pilots contemplating using such services should request and/or review an appropriate description of services and provider disclosure. This should include, but is not limited to, the type of weather product (e.g., current weather or forecast weather), the currency of the product (i.e., product issue and valid times), and the relevance of the product. Pilots and operators should be cautious when using unfamiliar weather products. |
