3.2.2NOTAM (L)
3.2.2.1NOTAM (L) 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.
3.2.2.2NOTAM (L) information is distributed
locally only and is not attached to the hourly weather
reports. A separate file of local NOTAMs is
maintained at each FSS for facilities in their areas
only. NOTAM (L) information for other FSS areas
must be specifically requested directly from the FSS
that has responsibility for the airport concerned.
NOTE−
DUATS vendors are not required to provide NOTAM (L)
information.
3.2.3FDC NOTAMs
3.2.3.1On those occasions when it becomes
necessary to disseminate information which is
regulatory in nature, the National Flight Data Center
(NFDC) in Washington, D.C., will issue an FDC
NOTAM. FDC NOTAMs contain such things as
amendments to published instrument approach
procedures (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.
3.2.3.2FDC NOTAMs are transmitted via Service A
only once and are kept on file at the FSS until
published or canceled. FSSs are responsible for
maintaining a file of current, unpublished FDC
NOTAMs concerning conditions within 400 miles of
their facilities. FDC information concerning conditions
that are more than 400 miles from the FSS, or
that is already published, is given only on request.
NOTE−
1.DUATS vendors will provide FDC NOTAMs only upon
site−specific requests using a location identifier.
2.NOTAM data may not always be current due to the
changeable nature of the national airspace system
components, delays inherent in processing the information,
and occasional temporary outages of the United States
NOTAM System. While en route, pilots should contact FSSs
and obtain updated information for their route of flight and
destination.
3.3An integral part of the NOTAM System is the
Notice to Airmen publication, published every
28days. Data is included in this publication to reduce
congestion on the telecommunications circuits and,
therefore, is not available via Service A. Once
published, this information is not provided during
pilot weather briefings unless specifically requested
by the pilot. The Notice to Airmen publication
contains four parts:
3.3.1Part 1 contains three sections.
3.3.1.1Notices which meet the criteria for
NOTAM(D) which are expected to remain in effect
for an extended period and FDC NOTAMs current at
the time of publication. Occasionally, some
NOTAM(L) and other unique information is
included in this section when it will contribute to
flight safety.
3.3.1.2Airports, Facilities, and Procedural
NOTAMs.
3.3.1.3General FDC NOTAMs.
3.3.2Part 2 contains Revisions to Minimum
EnRoute IFR Altitudes and Changeover Points
Amendments.
3.3.3Part 3 contains International Notices to
Airmen.
3.3.4Part 4 contains Graphic Notices.It includes
special notices and notices containing graphics
pertaining to almost every aspect of aviation; such as,
military training areas, large scale sporting events
that may attract media attention or draw large crowds
of aircraft, chart corrections and additions, and air
show information.
3.3.5The number of the last FDC NOTAM included
in the Notices to Airmen publication is noted on the
first page to aid the user in updating the listing with
any FDC NOTAMs which may have been issued
between the cut−off date and the date the publication
is received. All information contained will be carried
until the information expires, is canceled, or in the
case of permanent conditions, is published in other
publications, such as the Airport/Facility Directory.
3.3.6All new notices entered, excluding FDC
NOTAMs, will be published only if the information
is expected to remain in effect for at least 30 days after
the effective date of the publication.
