NOTAM Question

GWO 04/481 M16 TAXIWAY C AND TAXIWAY D CLOSED WITH EFFECT FROM OR EFFECTIVE FROM 0904291700-0905031300
GWO 04/495 M16 AD CLOSED 1400-2300 DAILY WITH EFFECT FROM OR EFFECTIVE FROM 0904301400-0905022300

I am trying to find what AD means. A baron was denied an instrument approach as the airport was closed EXCEPT for prior approval traffic. There is a model jet airshow going on this weekend at M16

AD not listed at gofir.com/aviation_abbreviations.htm

Any ideas what AD means?

Kinda worrisome had that Baron barged in VFR without contacting KJAN approach!

Aerodrome closed???
Not sure, that’s definitely not standardized terminology.

If you need a PPR for arrival then that suggests the runway is temporarily out of service, or worse, the airport is closed.

3

According to the official source, the FAA Contractions Publication, the contraction “AD” means aerodrome.

This publication is also available for download as a PDF.

I have the ATC clip which I will include in my video of today’s flight.

Initial KJAN approach reaction was the airport was closed, and my guess is the Baron said that they had prior approval (Baron must have been on 125.25 and I was on 123.9 so I never heard his end of the conversation.).

To be honest, looking at that NOTAM I probably wouldn’t have thought twice about going to Raymond and would have found myself in that Baron’s position.

Dami, I see you posted as I am previewing, thanks for the link.

Now the question is why in the dickens didn’t they use AP instead of AD? I realize MS feels like outside the US of A, but jeeez Aerodome???

Right… but “AP” is the standard abbreviation for “airport” in NOTAMS, hence the confusion. I agree with lieberma, that’s a vague NOTAM, it should clearly state there is a “hard” PPR for the airport instead of stating “AD closed”. Someone could misread, or not understand, and really screw themselves…

[edit] Posted same time as lieberma!

The third column in the contraction decoding indicates usage. The usage shown for “AD” is ICAO. Aren’t NOTAMS suppose to be formatted per ICAO rules?

7

Maybe, but as a 15+ year pilot I have never seen “AD” in a FAA NOTAM. Not normal.

8

It is and AP is ICAO in the very same reference.

I suspect AD would be most appropriate for countries that use aerodome as the term for airport.

We call 'em airports just like the rest of the country in good ole MS :stuck_out_tongue:

9

The new version of the NOTAM handbook, the good old 7930.2(M) changes the NOTAM abbreviation to AD ( aerodrome). The handbook changed last September…I don’t get to read too many real Notams anymore, but AD is what the new book uses.

Hmmm, isn’t your link from the same web source as Dami’s?

faa.gov/airports_airtraffic/ … CNTHME.HTM which eventually takes you to

faa.gov/airports_airtraffic/ … /2-1-A.htm (Dami provided this link) has AP listed as an acronym?

It’s ok, call me confused! :open_mouth:

11

Talking with another pilot, not sure how true or correct this may be, but he felt Aerodome is correct in the NOTAM. He thought Aerodome would mean airport AND airspace around the airport due to the model jets is closed hence AD.

If the airport was closed, lets say for runway construction, then the NOTAM would read AP.

Thoughts???

Dami linked to the contractions manual, , FAA order 7340.2.

I linked to the NOTAM Handbook, the 7930.2.

The contractions manual has thousands of contractions.

The NOTAM handbook tells the FSS ( and the Notam office) which contractions to use.

For example, section 1-2-1 of the NOTAM handbook:

e. All D NOTAMs shall have one of the following keywords as the first part of the text:

RWY, TWY, RAMP, APRON, AD, OBST, NAV, COM, SVC, AIRSPACE, (U), or (O).

And then later, the Notam book gets specific:

  1. AD (Aerodrome, including airport, heliport, helipads). NOTAMs pertaining to aircraft operations on or within 5 SM of an aerodrome, which encompasses airport, heliport, helipad, and maneuvering area, that is not covered under runways, taxiways, ramps, aprons, obstructions, navaids, services, communications, or airspaces.

EXAMPLES-
!LAL LAL AD GRASS LDG STRIP LCTD 400 S RWY 9R/27L 1700 X 55 AVBL VMC DALGT PPR SUN N FUN WEF 0804151100-0804232359

!CDB AK05 AD CLSD PERM

!RIU O88 AD HELI DCMSND

!AOO PA06 AD CLSD TSNT

Edit: I agree that the original NOTAM for this airport could have specified PPR.

Yep, that makes sense! Learn something new everyday. :wink:

Now let’s discuss why model airplanes are causing GA light twins to be waved off from a fully functional airport. :smiling_imp:

Per Phantomjet’s suggestion, the reason why I started this thread can be seen here
