Section 2. NOTAM System
When changes occur so
rapidly that time does not permit issuance on a chart or in an appropriate
publication, they are publicized as NOTAMs. Originators of airmen
information are expected to inform the National Flight Data Center (NFDC) in
sufficient time before the effective dates of changes to permit publishing
of aeronautical data on the various charts or in the appropriate
publications. NOTAMs are classified into four groups in accordance with
instructions in this order. The groups are:
a. NOTAM D.
Information that meets the criteria of this order and requires wide
dissemination via telecommunication and pertains to en route navigational
aids, civil public-use airports listed in the AFD, facilities, services, and
procedures. Information that may be beneficial to aircraft operations and is
not identified in
Appendix 2,of this order. These NOTAMs are identified with “(O)” as the
first part of NOTAM text.
b. FDC NOTAM.
Flight information that is regulatory in nature including, but not limited
to, changes to IFR charts, procedures, and airspace usage.
NOTAM. Issued by a flight service station to highlight or point out another
NOTAM; such as, an FDC or PJE NOTAM. This type of NOTAM will assist users in
cross-referencing important information that may not be found under an
airport or NAVAID identifier. Keywords in pointer NOTAMs shall match the
keywords in the NOTAM D that is being pointed out. Keywords in pointer
NOTAMs related to Temporary Flight Restrictions (TFR) shall be AIRSPACE.

area or facility involved.
b. ARTCCs are
responsible for forwarding FDC and special use airspace (SUA) and related
airspaces NOTAM information to the affected terminal facilities.

monitored NAVAID fails, the monitoring facility must be responsible for the
notification of all affected facilities, including ATC controlling

the local aviation companies, airline operation's offices, and interested
