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 airway NOTAMs, procedural 

NOTAMs, and NOTAMs that are general in nature 
and not tied to a specific airport/facility (for example, 
flight advisories and restrictions, open duration 
special security instructions, and special flight rules 
areas), Domestic Notices and International Notices. 
Domestic Notices and International Notices are 
found in the External Links section of the Federal 
NOTAM System (FNS) NOTAM Search System. 

(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) 

GPS RAIM availability for 1 hour before 

to 1 hour after ETA or a time specified by the pilot. 

(f) 

Other assistance as required. 

c.  Abbreviated Briefing. 

Request an Abbreviat-

ed 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 
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 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:
