For FDC NOTAM examples, see chapter 7.
must contain these elements from left to right in the following order:
exclamation point (!).
(the identifier of the accountability location; for example, JFK, FDC,
designator (the identifier of the affected facility or location – located
AFTER the NOTAM number).
activity, or surface designator(s) (when needed).
A surface designator is required with keywords RWY, TWY, and APRON.
segment (when needed).
feature, service, system, and/or components thereof (when needed).
description (when needed).
Lower limit/upper limit, or height, when needed.
Limits must be specified as SFC (surface). Up to 17,999, express in feet
MSL; for example, 275FT, 1225FT (MSL must not be written). For 18,000 and
above, express in in flight levels (FL); for example, FL180, FL550, or UNL
(altitudes greater than 60,000FT). Heights AGL may be added in parentheses
The changed condition or status being reported, when needed; for example:
CLSD, OUT OF SERVICE, NOT AVBL, NOT LGTD, FLAGGED, OBSC, UNREL, ON CONS.
(optional). Other information considered important to the pilot.
if needed. A single NOTAM may be originated for a scheduled
condition/activity that will recur during the effective period. Specify the
schedule between the condition/activity and the effective time string. The
days of the week must be specified before the scheduled time. The term “DLY”
(daily) indicates the event will occur at the same time during the stated
time period. The NOTAM effective time and expiration time must be compatible
with the scheduled time.
time. A 10digit datetime group (YYMMDDHHMM) must be used to indicate the
effective time and expiration time of the NOTAM. The effective time and
expiration time must be separated by a hyphen “.” The effective time
indicates the date/time a condition will exist or begin. The expiration time
is the expected return to service, return to normal status time, or the time
the activity will end.
the NOTAM duration is uncertain, the approximate expiration time must be
indicated by using a datetime group followed immediately by “EST”
(estimate). Any NOTAM which includes an “EST” must be canceled or replaced
before the expiration time specified in the NOTAM, as the NOTAM will not
autoexpire. FDC NOTAMs relating to instrument flight procedures must not
be canceled and reissued. (Reference FAA Order 8260.19, chapter 2, section
a NOTAM is originated to advertise a permanent condition that will be
published in a publication, chart or database, “PERM” should be inserted as
the expiration date in lieu of a 10digit datetime group. The NOTAM
originator is responsible for canceling the NOTAM upon publication.
neither “EST” nor “PERM” is used, the NOTAM will autoexpire at the
issued when the condition of a number of facilities, NAVAIDs, services, or
landing areas/runways are related to the same event (for example, date/time,
facility closing, part-timing, runway closures, etc.) must be issued as
NOTAM concerning a specific aid, service, or hazard must be a complete
report including all deviations unless reference is made to other
restrictions already published.
d. If information is published elsewhere and is
still valid, reference must be made to that publication with the statement,
“PLUS SEE (publication).” A NOTAM issued not stating “PLUS SEE
(publication)” indicates the NOTAM replaces previously published similar
must state the abnormal status of a component of the NAS and not the normal
status. The only exception is for data that has been published and is being
replaced; for example, RWY 9/27 OPEN.
Maintain separate accountability (NOTAM
file) for each location whose weather report is disseminated via WMSCR and
for the location of the tiein FSS.
NOTAMs for an FAAmonitored weather reporting location whose report is
disseminated via WMSCR under the location identifier of the weather report.
all other NOTAMs under the location identifier of the tiein FSS. This
includes NOTAMs for weather reporting locations whose report is not
disseminated via WMSCR.
FAA Order JO 7930.2, chapter 2, Aeronautical
NOTAM accountability changes by mail, administrative message, or FAX when
known sufficiently in advance. When the published accountability for a NOTAM
is incorrect, change it by issuing a NOTAM under the published
accountability. As soon as practicable after issuance, contact the USNOF by
telephone or message and request they make the accountability change in the
USNS tables. Issue all subsequent NOTAMs under the corrected accountability.
If there are any current NOTAMs for the location, cancel and reissue those
NOTAMs under the new accountability after the USNS tables have been changed.
Notify Aeronautical Information Management of any NOTAM accountability
