Special Activity Airspace (SAA) NOTAMs, and
Military NOTAMs.

1. NOTAM (D)

 information  is disseminated for

all navigational facilities that are part of the National
Airspace System (NAS), all public use airports,
seaplane bases, and heliports listed in the Chart
Supplement U.S. The complete file of all NOTAM
(D) information is maintained in a computer database
at the Weather Message Switching Center (WMSC),
located in Atlanta, Georgia. This category of
information is distributed automatically via Service
A telecommunications system. Air traffic facilities,
primarily FSSs, with Service A capability have
access to the entire WMSC database of NOTAMs.
These NOTAMs remain available via Service A for
the duration of their validity or until published. Once
published, the NOTAM data is deleted from the
system. NOTAM (D) information includes such data
as taxiway closures, personnel and equipment near or
crossing runways, and airport lighting aids that do not
affect instrument approach criteria, such as VASI.

All NOTAM Ds must have one of the keywords listed
in TBL 5

−1−1 as the first part of the text after the

location identifier.


On those occasions when

it becomes necessary to disseminate information
which is regulatory in nature, the National Flight Data
Center (NFDC), in Washington, DC, will issue an
FDC NOTAM. FDC NOTAMs contain such things as
amendments to published IAPs and other current
aeronautical charts. They are also used to advertise
temporary flight restrictions caused by such things as
natural disasters or large-scale public events that may
generate a congestion of air traffic over a site.


NOTAM data may not always be current due to the
changeable nature of national airspace system compo-
nents, delays inherent in processing information, and
occasional temporary outages of the U.S. NOTAM system.
While en route, pilots should contact FSSs and obtain
updated information for their route of flight and

3. Pointer NOTAMs.

NOTAMs issued by a

flight service station to highlight or point out another
NOTAM, such as an FDC or NOTAM (D) NOTAM.
This type of NOTAM will assist users in

−referencing important information that may

not be found under an airport or NAVAID identifier.
Keywords in pointer NOTAMs must match the
keywords in the NOTAM that is being pointed out.
The keyword in pointer NOTAMs related to
Temporary Flight Restrictions (TFR) must be


 These NOTAMs are issued

when Special Activity Airspace will be active outside
the published schedule times and when required by
the published schedule. Pilots and other users are still
responsible to check published schedule times for
Special Activity Airspace as well as any NOTAMs
for that airspace.

5. Military NOTAMs.

NOTAMs pertaining

to U.S. Air Force, Army, Marine, and Navy
navigational aids/airports that are part of the NAS.

c. Notices to Airmen Publication (NTAP).


NTAP is published by Mission Support Services,
ATC Products and Publications, every 28 days.  Data
of a permanent nature can be published in the NTAP
as an interim step between publication cycles of the
Chart Supplement U.S. and aeronautical charts. The
NTAP is divided into three parts:


Part 1, provided by NFDC, contains Part 95

Revisions, Revisions to Minimum En Route IFR
Altitudes and Changeover Points.


Part 2, International NOTAMs, is divided into

two sections: 


Section 1, International Flight Prohibi-

tions, Potential Hostile Situations, and Foreign


Section 2, International Oceanic Airspace



Part 3, Graphic Notices, compiled by ATC

Products and Publications from data provided by
FAA service area offices and other lines of business,
contains special notices and graphics pertaining to
almost every aspect of aviation such as: military
training areas, large scale sporting events, air show
information, Special Traffic Management Programs
(STMP), and airport-specific information. This part
is comprised of 6 sections: General, Special Military
Operations, Airport and Facility Notices, Major
Sporting and Entertainment Events, Airshows, and
Special Notices.
