Preflight Briefing

Leidos Preflight Briefing


Obtaining A Preflight Briefing:

Standard Briefing:

Abbreviated Briefing:

  • Request an Abbreviated 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 information source already received so that the briefer can limit the briefing to the information that you have not received and/or appreciable changes in meteorological/aeronautical conditions since your previous briefing
  • To the extent possible, the briefer will provide the information in the sequence shown for a Standard Briefing
  • If you request only one or two specific items, the briefer will advise you if adverse conditions are present or forecast (Adverse conditions 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

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 before departure to obtain such items as adverse conditions, current conditions, updated forecasts, winds aloft, and NOTAMs, etc.

Inflight Briefing:

  • Pilots are encouraged to conduct a self-briefing using online resources or obtain your preflight briefing by telephone or in person (Alaska only) 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 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. En Route advisories tailored to the phase of flight that begins after climb-out and ends with descent to land are provided upon pilot request. Besides Flight Service, there are other resources available to the pilot in flight, including:
    • Automated Dependent Surveillance-Broadcast:

      • Free traffic, weather, and flight information are available on Automated Dependent Surveillance-Broadcast, or ADS-B, In receivers that can receive data over 978 MHz (UAT) broadcasts. These services are available across the nation to aircraft owners who equip with ADS-B In, with further advances coming from airborne and runway traffic awareness. Even search-and-rescue operations benefit from accurate ADS-B tracking
    • Flight Information Service-Broadcast:

      • Flight Information Service-Broadcast, or FIS-B, is a free service; but is only available to aircraft that can receive data over 978 MHz (UAT). FIS-B automatically transmits a wide range of weather products with national and regional focus to all equipped aircraft. Having current weather and aeronautical information in the cockpit helps pilots plan more safe and efficient flight paths, as well as make strategic decisions during flight to avoid potentially hazardous weather
    • Pilots are encouraged to provide a continuous exchange of information on weather, winds, turbulence, flight visibility, icing, etc., between pilots and inflight specialists. Pilots should report good weather as well as bad, and confirm expected conditions as well as unexpected. Remember that weather conditions can change rapidly and that a "go or no go" decision, as mentioned in AIM paragraph 7-1-4b2, should be assessed at all phases of flight

Self Briefing:

  • Pilots may opt to conduct a self briefing in accordance with AC 91-92

Preflight Briefing Knowledge Quiz:


  • Available aviation weather reports, forecasts, and aviation weather charts display at each AFSS/FSS
    • Pilots should feel free to use these self briefing displays where available or to ask for a briefing or assistance from the specialist on duty
  • 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 can present the information in a logical sequence and lessens the chance of overlooking important items
  • 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
  • If, for whatever reason your flight is delayed more than two hours after your last briefing, it is recommended you receive an abbreviated brief to check for anything not proceeding as forecast
  • For more information, a paper copy of Aviation Weather Services: FAA Advisory Circular 00-45H, Change 1&2 (FAA Handbooks series) [Amazon] is available for purchase
  • The FAA publistes a course for conducting preflight self-briefings for IFR pilots
  • Additional resources, which do not meet the requirements for a preflight weather brief, such as NOAA's Standard Briefing, are available
  • While checking your local weather channel may provide some insight into your flight, it is not tailored for aviators, and therefore is not a qualifying resource for flight planning without proper review of AVIATION reports and forecasts
  • Consider cross-checking weather reports against weather cameras provided by NOAA or the FAA's weather camera program
