I've a difficulty to use the Notam decoder on this Notam.

V0018/24 NOTAMN 
Q) OOMM/QPIAU/I/BO/A/000/999/2336N05816E005 
A) OOMS 
B) 2401250001 
C) 2405160001 
E) [US DOD PROCEDURAL NOTAM] INSTRUMENT APPROACH PROCEDURE NOT AUTHORIZED ILS RWY 08L.

Also what is US DOD in this context?

In short

  • The Notam says the IFR approach for ILS RWY 08L at Muscat International Airport (Oman) is not allowed until 16/05/2024 00:01 UTC.

  • US DOD ➫ US Department of Defense. The DoD issues this Noram because there is an agreement allowing the United States, which have an important naval base in Oman, to use Oman's Muscat military airfields.


How to decode

  • V0018/2024 NOTAM ➫ Notam reference, N ➫ New Notam
  • Q ➫ Always Q
    • OOMM ➫ Related to Muscat control center (Oman)
    • QPIAU ➫ Instrument procedure is not available (QQCode, PI ➫ Instrument approach procedure, AU ➫ Unavailable)
    • I ➫ IFR
    • BO ➫ Purpose: B ➫ Immediate attention, O ➫ flight operations
    • A ➫ Scope is the aerodrome
    • 000/999 ➫ From sea level to unlimited
    • 2336N05816E005 ➫ Center position is 23°36'N 058°16'E, radius 5NM (this is the reference point of the aerodrome)
  • A field ➫ Location, aerodrome or FIR, OOMSMuscat International Airport (Oman)
  • B field ➫ Beginning, 2401250001 ➫ Valid from 25/01/2024 00:01 UTC
  • C field ➫ End, 2405160001 ➫ Valid to 16/05/2024 00:01 UTC
  • E field ➫ Notam text, [US DOD PROCEDURAL NOTAM] INSTRUMENT APPROACH PROCEDURE NOT AUTHORIZED ILS RWY 08L

US DoD Notams are aimed to military and civil crews

It is a procedural Notam part of FLIP, issued by US DoD using DINS (which is interfaced with the AFTN). FLIP is a special information/documentation/mapping system provided by US agencies for foreign airfields. It is used by US military and also civil pilots via a subscription. This Notam is part of FLIP:

[...] Foreign civil/military flight crews who use US DoD FLIP should access DoD procedural NOTAM (V series) or DoD chart/FLIP/DAFIF NOTAM (W series). V/W series NOTAMs are available via:

  1. Primary or secondary DINS Query websites.
  2. Aeronautical Fixed Telecommunication Network (AFTN), [...]

Most of this information can be decoded online.

US Department of Defense. This is alerting DoD aircrews that they may not fly this procedure.

  • $\begingroup$ It does make me wonder if Oman has put out a matching civil NOTAM for that ILS at Muscat... $\endgroup$ Apr 20 at 1:22
  • $\begingroup$ A DoD procedure NOTAM does not have to be against a military procedure. Rather, it is issued when DoD aircrews may not use that procedure published in FLIP, as mins explained in his answer. $\endgroup$

  • $\begingroup$ Yeah, I asked my question because I'm wondering if the issue is that the procedure somehow is nonconformant with US DoD standards in a way that renders it unflyable for DoD users but isn't an issue for civil air traffic, or if the procedure is NA because, say, the localizer transmitter is INOP, meaning that it's not usable for civil traffic either and Oman would have a civil NOTAM out saying that civil users can't fly the procedure either $\endgroup$ Apr 23 at 1:14

    $\begingroup$ DoD will not write a NOTAM against a procedure if the host nation has already written one. While it is possible that a procedure does not conform to US standards, the likely result would be that it is not published in FLIP in the first place. $\endgroup$

    $\begingroup$ Let me also say that this should not be a DoD procedure NOTAM, since it is not a DoD procedure. Rather, the NOTAM should be a DoD FLIP and DAFIF one. It’s nuanced, but the DoD is not the procedure design authority. $\endgroup$
