NOTAM Decode



NOTAM (Notice To Air Men): A notice distributed by means of telecommunication containing information concerning the establishment,condition or change in any aeronautical facility,service,procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operation.



ICAO NOTAM format

The format of NOTAM is defined in Annex 15 to the International Convention on Civil Aviation.


A1484/02 NOTAMN


Q) EGTT/QMRXX/IV/NBO/A/000/999/5129N00028W005


A) EGLL


B) 0208231540


C) 0210310500 EST


E) RWY 09R/27L DUE WIP NO CENTRELINE, TDZ OR SALS LIGHTING AVBL

Notam Decoder

A1484/02 - one letter to indicate the Series, a 4-digit NOTAM number followed by a stroke and two digits to indicate the year.

NOTAMN - Suffix N Indicates this is a new NOTAM. Other options are R for NOTAM replacing another or C for one cancelling another.

Q) EGTT/QMRXX/IV/NBO/A/000/999/5129N00028W005

This is the "Q" or qualifier line, it always starts Q) and contains the following fields, each separated by a stroke.

FIR (here EGTT, London FIR)

NOTAM Code, a 5 letter code starting with Q, defined in Annexe 15. Here QMR indicates that it concerns a Runway. XX indicates that remaining detail is in Plain Language. In this particular case the text shows that certain runway lighting is unavailable. Strictly speaking under ICAO rules this should have appeared as separate NOTAM for each type of lighting. QLCAS is the code for centreline lighting u/s QLZAS is the code for Touch Down Zone lighting u/s and  QLAAS is the code for Approach Lighting u/s (note in all cases AS indicates unserviceable). The use of QMRXX here is a sensible compromise that reduces the number of NOTAM from three to one. A full list of codes is included in ICAO document 8126 (Aeronautical Information Services Manual).

IV - Indicates that this is significant for IFR and VFR traffic

NBO - indicates for immediate attention of aircraft operators, for inclusion in PIB's and Operationally significant for IFR flights

A - Indicates scope, here Aerodrome, others are E (en-route) or W (nav warning)

000/999 - lower and upper limits expressed as a flight level. In this case it has been left as the default as it is not applicable.

5129N00028W005 - Indicates the geographical centre and radius of influence, always this number of digits. In this case the radius is 5 n.m.

A) EGLL - ICAO indicator of the aerodrome or FIR (London Heathrow) can include more than one FIR

B) 0208231540 - Date/time group (UTC) when this NOTAM becomes effective

C) 0210310500 EST - Date/time group (UTC) when the NOTAM ceases to be effective. Note "EST" means "estimated" (NOT Eastern Standard Time!). All NOTAM with EST remain in force until cancelled or replaced.

E) RWY 09R/27L DUE WIP NO CENTRELINE, TDZ OR SALS LIGHTING AVBL - text of the notam using ICAO abbreviations.

Decode of this is "Runway 09/27 due to work in progress no centreline, touchdown zone or simple approach lighting system available"

Here's the whole thing again

A1484/02 NOTAMN


Q) EGTT/QMRXX/IV/NBO/A/000/999/5129N00028W005


A) EGLL


B) 0208231540


C) 0210310500 EST


E) RWY 09R/27L DUE WIP NO CENTRELINE, TDZ OR SALS LIGHTING AVBL

and here's the same thing as it appears in the PIB produced by ANAIS

AGA : FROM 02/08/23 15:40 TO 02/10/31 05:00 EST           A1484/02


      E)RWY 09R/27L DUE WIP NO CENTRELINE, TDZ OR SALS LIGHTING AVBL


You can see that the Q line is omitted entirely, A) has been stripped out because it appears as the header to the section and B) and C) have been reformatted and placed in the first line. AGA has been derived from the Q Code "QMR" (see Annex 15)


INTERNATIONAL NOTAM (Q) CODES

This appendix is to be used to interpret the contents of coded international NOTAM's.

a. A NOTAM code group contains five letters. The first letter is always the letter "Q'' to indicate a code abbreviation for use in the composition of NOTAM's.

b. The second and third letters identify the subject being reported. (See Second and Third Letter Decode Tables).

c. The fourth and fifth letters identify the status of operation of the subject being reported. (See Fourth and Fifth Letter Decode Tables).
