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.


A review of the Notices to Airmen

Publication for pertinent NOTAMs and Special



Approximate density altitude data.


Information regarding such items as air

traffic services and rules, customs/immigration

procedures, ADIZ rules, search and rescue, etc.


GPS RAIM availability for 1 hour before

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


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

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.


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 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.


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




5. En Route Flight Advisory Service



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-
