Flight Services Computer Functions
E-1. CONFIRMING ACCEPTANCE BY THE NOTAM SYSTEM
a. When a new NOTAM is accepted into the NOTAM file, a copy of the NOTAM with the NOTAM number will be returned back to the originating facility.
b. If the NOTAM is rejected, an NS-generated service message will be relayed back to the facility of origin indicating the reason for rejection as shown in paragraph 4-5-2, NOTAM Service Messages.
E-2. TRANSMISSION BY ANOTHER FACILITY
When unable to transmit a NOTAM directly into the system due to equipment failure or other situation, relay the information to an FSS and request that the data be transmitted into the system.
E-3. CANCELLATION OF NOTAMs
To cancel a NOTAM, use the same NOTAM/serial number assigned to the original NOTAM by the NS 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 must receive the same dissemination as the NOTAM it cancels. Do not carry the NOTAM text in the cancellation.
EXAMPLE-
!ABC C05/005
E-4. MONITORING
a. All input transmissions from a facility are monitored by the NS computer for the presence of an ADP code. The validity of the station identifier, format, and times are also checked before the NS computer assigns a number and updates the NOTAM master file.
b. Errors in the station identifier or the format will result in a computer-generated service message being sent to the facility of origin. (See paragraph 4-5-2 for examples). The service message will identify the NOTAM parameter which was in error. A rejection (R) requires corrective action as soon as possible.
E-5. NOTAM SERVICE MESSAGES
If data is entered incorrectly, it will be rejected. Each rejection will be preceded with a service message (SVC) explaining the cause for the rejection.
E-6. RETRIEVING FDC NOTAMS
a. Upon issuance, all FDC NOTAMs are given all circuit distribution and are stored in the NS. FDC NOTAMs remain in the NS for the duration of their validity. FDC NOTAM cancellations remain in the NS for 72-hours after transmission.
b. FDC NOTAMs 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
DDHHMM KFODYFYX
)SVC RQ FDC LOC=CID NT=Y/2735
(b) When only the number is known:
EXAMPLE-
GG KDZZNAXX
DDHHMM KFODYFYX
)SVC RQ FDC NT=Y/2735
2. To request all FDC NOTAMs for a given location:
EXAMPLE-
GG KDZZNAXX DDHHMM 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.
E-7. RETRIEVING MILITARY NOTAMS
Formats for retrieving military NOTAMS via NADIN are as follows:
a. A request for a single NOTAM for a given location:
EXAMPLE-
SVC B:
GG KDZZNAXX
DDHHMM KDCAYFYX
)SVC RQ MIL ACC=KADW NT= M0134/YY
b. A request for all military NOTAMs for a given location:
EXAMPLE-
SVC B:
GG KDZZNAXX
DDHHMM KSJTYFYX
)SVC RQ MIL LOC=KNGP
c. A request for all military NOTAMs for multiple locations (maximum of eight):
EXAMPLE-
SVC B:
GG KDZZNAXX
DDHHMM KEKNYFYX
)SVC RQ MIL LOC= KADW, KDAA, KNGP, KNGU, KNUW, KHST, KHIF
NOTE-
All facilities must use their particular equipment's keyboard equivalent of the closed parenthesis or equal symbol as appropriate.
d. To review all NOTAMs for a joint-use airport (for example, CHS), both civil (CHS) and military (KCHS) NOTAMs must be retrieved.
e. To request all NOTAMs for a given location from all files (domestic, FDC, international, and military) that meets the military NOTAM criteria:
EXAMPLE-
SVC B:
GG KDZZNAXX
DDHHMM KEKNYFYX
)SVC RQ MIL LOC= KADW
E-8. SERVICE MESSAGES
a. Receipt of the NS generated service message “NOTAMS FOUND 0” indicates that there are no military NOTAMs on file for the number or location requested.
b. The following is an example of a receipt of the NS cancellation of a military NOTAM.
EXAMPLE-
SVC B:
GG KDZZNAXX
DDHHMM KADW
MYYYY/YY NOTAMC M0142/YY
B) KADW
c. Formats for retrieving international NOTAMs via NADIN are as follows:
1. A request for a single NOTAM for a given accountability identifier:
EXAMPLE-
SVC B:
GG KDZZNAXX

)SVC RQ INT ACC= MYNNYNYX NT=A0211/YY
Reply:
GG KDCAYFYX 042105 KDZZNAXX
)SVC RQ INT ACC= MYNNYNYX NT=A0211/YY

Q) MYNA/QMRLC/IV/NBO/A/000/999/ 2502N07728W005
A) MYNN
B) YY 11181730
C) PERM
E) RWY 05 CLSD TO BOTH LDG AND DEP ACFT BUT MAY BE USED FOR TAX.
NOTE-
The Bahamas International NOTAM office issued a new NOTAM numbered A0211 and it was the 211th NOTAM issued for 2013. This NOTAM affected Nassau International Airport (MYNN) with a start time of November 18, 2013, at 1730 UTC and will be permanent. The condition is that Runway 5 is closed to both landing and departing aircraft but may be used for taxiing.
