Section 4. CANCELING/EXTENDING
NOTAMs
4-4-1. EXTENDING NOTAM DURATION
When there is a need
to extend an existing NOTAM time duration, cancel the original NOTAM and
reissue the data as a new NOTAM with the new time.
4-4-2. CANCELLATION
OF NOTAMs
a. To cancel a
NOTAM, use the same serial number assigned to the original NOTAM by the USNS
computer, preceded by the letter “C.” If the serial number of a NOTAM
cancellation is invalid (number not in a master file), no action is taken
within the NOTAM system. A cancellation shall receive the same dissemination
as the NOTAM it cancels. Do not carry the NOTAM text in the cancellation.
b. Stations
canceling NOTAMs shall check the NOTAM data to insure the NOTAMs deletion.
Retransmit cancellations not acted upon.
c. Cancel
NOTAMs containing erroneous information and reissue. Transmit a new NOTAM
when data is received amending a current NOTAM, and cancel the previous
NOTAM.
4-4-3. CANCELING
PUBLISHED NOTAM DATA
a. When data
appearing in a NOTAM is printed correctly in a publication or on a chart,
cancel the NOTAM, but not the data. The cancellation must be formatted in
the following manner:
EXAMPLES-
!ABC C05/005 PUBLISHED
or
!DEF C06/006 CHARTED
NOTE-
1. A cancellation which is transmitted without an explanation
means the NOTAM is canceled; e.g., !GHI C07/007
2. This
type of cancellation is used by non-automated users.
b. NOTAMs must
remain current until the data is published in one or more of the following,
with the exception of NAVAID NOTAMs, which must remain in effect until the
NAVAID is returned to service or decommissioned.
1. Airport/Facility
Directory (AFD).
2. En Route Low
Altitude Charts.
3. En Route
High Altitude Charts.
4. Instrument
Approach Procedures (IAPs).
5. Notice to
Airmen Publication.
NOTE-
The Notice to Airmen Publication (NTAP) is not an accepted medium for FDC
NOTAMs relating to instrument approach and obstacle departure procedures and
airways. These NOTAMs must remain current until published in the Terminal
Procedures Publication (TPP) or applicable en route chart.
6. Standard
Terminal Arrivals (STARs).
7. Departure
Procedures (DPs).
8. Supplements
(Alaska and Pacific).
9. Charts (VFR):
(a) Sectional
Charts.
(b) World
Aeronautical Charts (WACs).
(c) Terminal
Area Charts (TACs).
NOTE-
NOTAMs for Prohibited Areas P-40, P-49, and P-56, even if published on a
chart, will not be deleted from the database. This would also include any
published FDC (TFR) NOTAMs in the Washington, DC, Special Flight Rules Area.
c. NOTAMs
concerning Army airfield operations, in addition to the above listed
sources, must be researched in the Army Aviation Flight Information
Bulletin, if applicable.
