9.ATC Delays. Any known ATC delays and flow control advisories which might affect the proposed flight. 10.Pilots may obtain the following from flight service station briefers upon request: (a) Information on SUA and SUA.related airspace, except those listed in paragraph 7.1.4b8. NOTE. 1.For the purpose of this paragraph, SUA and related airspace includes the following types of airspace: alert area, military operations area (MOA), warning area, and air traffic control assigned airspace (ATCAA). MTR data includes the following types of airspace: IFR training routes (IR), VFR training routes (VR), and slow training routes (SR). 2.Pilots are encouraged to request updated information from ATC facilities while in flight. (b)A review of the Notices to Airmen Publication for pertinent NOTAMs and Special Notices. (c)Approximate density altitude data. (d)Information regarding such items as air traffic services and rules, customs/immigration procedures, ADIZ rules, search and rescue, etc. (e)LORAN.C NOTAMs, available military NOTAMs, and runway friction measurement value NOTAMs. (f)GPS RAIM availability for 1 hour before to 1 hour after ETA or a time specified by the pilot. (g)Other assistance as required. c.Abbreviated Briefing. Request an Abbrevia-ted Briefing when you need information to supplement mass disseminated data, update a previous briefing, or when you need only one or two specific items. Provide the briefer with appropriate background information, the time you received the previous information, and/or the specific items needed. You should indicate the source of the information already received so that the briefer can limit the briefing to the information that you have not received, and/or appreciable changes in meteorologi-cal/aeronautical conditions since your previous briefing. To the extent possible, the briefer will provide the information in the sequence shown for a Meteorology 7.1.7 Standard Briefing. If you request only one or two specific items, the briefer will advise you if adverse conditions are present or forecast. (Adverse condi-tions contain both meteorological and/or aeronautical information.) Details on these conditions will be provided at your request. International data may be inaccurate or incomplete. If you are planning a flight outside of U.S. controlled airspace, the briefer will advise you to check data as soon as practical after entering foreign airspace, unless you advise that you have the international cautionary advisory. d.Outlook Briefing. You should request an Outlook Briefing whenever your proposed time of departure is six or more hours from the time of the briefing. The briefer will provide available forecast data applicable to the proposed flight. This type of briefing is provided for planning purposes only. You should obtain a Standard or Abbreviated Briefing prior to departure in order to obtain such items as adverse conditions, current conditions, updated forecasts, winds aloft and NOTAMs, etc. e.When filing a flight plan only, you will be asked if you require the latest information on adverse conditions pertinent to the route of flight. f.Inflight Briefing. You are encouraged to obtain your preflight briefing by telephone or in person before departure. In those cases where you need to obtain a preflight briefing or an update to a previous briefing by radio, you should contact the nearest AFSS/FSS to obtain this information. After communications have been established, advise the specialist of the type briefing you require and provide appropriate background information. You will be provided information as specified in the above paragraphs, depending on the type of briefing requested. In addition, the specialist will recommend shifting to the Flight Watch frequency when conditions along the intended route indicate that it would be advantageous to do so. Remember that weather conditions can change rapidly and that a “go or no go” decision, as mentioned in paragraph 7.1.4b2, should be assessed at all phases of flight. g.Following any briefing, feel free to ask for any information that you or the briefer may have missed or are not understood. This way, the briefer is able to present the information in a logical sequence, and lessens the chance of important items being overlooked. 7.1.5. En Route Flight Advisory Service (EFAS)a. EFAS (radio call “Flight Watch”) is a service specifically designed to provide en route aircraft with timely and meaningful weather advisories pertinent to the type of flight intended, route of flight, and altitude. In conjunction with this service, EFAS is also a central collection and distribution point for pilot reported weather information. EFAS is provided by specially trained FSS specialists controlling multiple Remote Communications Outlets covering a large geographical area and is normally available throughout the conterminous U.S. and Puerto Rico from 6 a.m. to 10 p.m. EFAS provides communica-tions capabilities for aircraft flying at 5,000 feet above ground level to 17,500 feet MSL on a common frequency of 122.0 MHz. Discrete EFAS frequencies have been established to ensure communications coverage from 18,000 through 45,000 MSL serving in each specific ARTCC area. These discrete frequencies may be used below 18,000 feet when coverage permits reliable communication. NOTE. When an EFAS outlet is located in a time zone different from the zone in which the flight watch control station is located, the availability of service may be plus or minus one hour from the normal operating hours. b.In some regions of the contiguous U.S., especially those that are mountainous, it is necessary to be above 5000 feet AGL in order to be at an altitude where the EFAS frequency, 122.0 MHz, is available. Pilots should take this into account when flight planning. Other AFSS communication frequencies may be available at lower altitudes. See FIG 7.1.2. c.Contact flight watch by using the name of the ARTCC facility identification serving the area of your location, followed by your aircraft identifica-tion, and the name of the nearest VOR to your position. The specialist needs to know this approximate location to select the most appropriate transmitter/receiver outlet for communications coverage. |
