7-1-5. Preflight Briefing
a. Flight Service is one of the primary sources for
obtaining preflight briefings and to file flight plans by
phone or the Internet. Flight Service Specialists are
qualified and certificated as Pilot Weather Briefers by
the FAA. They are not authorized to make original
forecasts, but are authorized to translate and interpret
available forecasts and reports directly into terms
describing the weather conditions which you can
expect along your flight route and at your destination.
Prior to every flight, pilots should gather all
information vital to the nature of the flight. Pilots can
receive a regulatory compliant briefing without
contacting Flight Service. Pilots are encouraged to
use automated resources and review AC 91-92,
Pilot"s Guide to a Preflight Briefing, for more
information. Pilots who prefer to contact Flight
Service are encouraged to conduct a self-brief prior
to calling. Conducting a self-brief before contacting
Flight Service provides familiarity of meteorological
and aeronautical conditions applicable to the route of
flight and promotes a better understanding of weather
information. Three basic types of preflight briefings
(Standard, Abbreviated, and Outlook) are available
to serve the pilot"s specific needs. Pilots should
specify to the briefer the type of briefing they want,
along with their appropriate background information.

Meteorology

This will enable the briefer to tailor the information
to the pilot"s intended flight. The following
paragraphs describe the types of briefings available
and the information provided in each briefing.
REFERENCE-
AIM, Para 5-1-1, Preflight Preparation, for items that are required.

b. Standard Briefing. You should request a
Standard Briefing any time you are planning a flight
and you have not received a previous briefing or have
not received preliminary information through online
resources. 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 dats soon as practical after entering
foreign airspace, unless you advise that you have the
international cautionary advisory. The briefer will
automatically provide the following information in
the sequence listed, except as noted, when it is
applicable to your proposed flight.
1. Adverse Conditions. Significant meteoro
logical and/or aeronautical information that might
influence the pilot to alter or cancel the proposed
flight; for example, hazardous weather conditions,
airport closures, air traffic delays, etc. Pilots should
be especially alert for current or forecast weather
that could reduce flight minimums below VFR or
IFR conditions. Pilots should also be alert for any
reported or forecast icing if the aircraft is not certified
