Section 2. Cancellation/Expiration

7-2-1. FDC NOTAM EXPIRATION

The NOTAM issuing authority is responsible for canceling FDC NOTAMs.

7-2-2. CANCELING FDC NOTAMs

a. The issuing authority must issue a cancellation to an FDC NOTAM before the expiration time. An FDC NOTAM must be issued to cancel an FDC NOTAM and must be stated to the originator of the FDC NOTAM when the original FDC NOTAM is received.

b. When a new FDC NOTAM is issued to correct or in any way change a previously issued FDC NOTAM, a new NOTAM will be issued and a separate cancellation NOTAM will be issued to cancel the old NOTAM.

EXAMPLE-
!FDC 0/1606 CANCEL 0/1181 MSP
!FDC 0/1607 CANCEL 0/1605 POM

7-2-3. FDC NOTAM LIST

Twice each day, the USNOF transmits a list of FDC NOTAM numbers issued during the previous 12 and 24 hours. The list is transmitted as a numbered FDC NOTAM between 0515 and 0545 and between 1715 and 1745 UTC. The 0500 list is a summary of the preceding 12 hours. The 1700 list is a summary of the preceding 24 hours. Each previous list is canceled by a separate FDC NOTAM.

EXAMPLE-
!FDC 0/1611 FDC LIST JUN 230531
!FDC 0/1608 ELY
!FDC 0/1609 FDC
!FDC 0/1610 ABC

7-2-4. RETRIEVING FDC NOTAMs

a. Upon issuance, all FDC NOTAMs or FDC NOTAM cancellations are given all circuit distribution and are stored in the USNS. FDC NOTAMs remain in the USNS for the duration of their validity. FDC NOTAM cancellations remain in the USNS for 72 hours after transmission.

b. FDC NOTAMs and FDC NOTAM cancellations may be retrieved via request/reply. To minimize response delays, each FDC NOTAM and FDC NOTAM cancellation to be retrieved should be requested individually.

1. To retrieve an individual FDC NOTAM by number:

(a) When the location identifier and number are known:

EXAMPLE-
AIS:
GG KDZZNAXX DTG KFODYFYX
)SVC RQ FDC LOC=CID NT=0/2735

(b) When only the number is known:

EXAMPLE-
GG KDZZNAXX DTG KFODYFYX
)SVC RQ FDC NT=0/2735

2. To request all FDC NOTAMs for a given location:

EXAMPLE-
GG KDZZNAXX DTG KCOUYFYX
)SVC RQ FDC LOC=MCI

NOTE-
All facilities must use their particular equipment's keyboard equivalent of the closed parenthesis or equal symbol as appropriate.
