NOTAM FORMAT [Figure or form omitted from this preview — available in the Avioverse workspace library.]

INSTRUCTIONS FOR THE COMPLETION OF THE NOTAM FORMAT

1.General The qualifier line (Item Q) and all identifiers (Items A to G inclusive) each followed by a closing parenthesis, as shown in the format, shall be transmitted unless there is no entry to be made against a particular identifier.

2.NOTAM numbering Each NOTAM shall be allocated a series identified by a letter and a four-digit number followed by a stroke and a two-digit number for the year (e.g. A0023/03). Each series shall start on 1 January with the number 0001.

3.Qualifiers (Item Q) Item Q is divided into eight fields, each separated by a stroke. An entry shall be made in each field. Examples of how fields are to be filled in are shown in the Aeronautical Information Services Manual (ICAO Doc 8126). The definition of the field is as follows:

1.FIR a) If the subject of the information is geographically located within one FIR, the ICAO location indicator shall be that of the FIR concerned. When an aerodrome is situated within the overlying FIR of another Member State, the first field of Item Q shall contain the code for that overlying FIR (e.g. Q) LFRR/…A) EGJJ); or, if the subject of the information is geographically located within more than one FIR, the FIR field shall be composed of the ICAO nationality letters of the Member State originating the NOTAM followed by ‘XX’. The location indicator of the overlying UIR shall not be used. The ICAO location indicators of the FIRs concerned shall then be listed in Item A or the indicator of the Member State or the delegated entity which is responsible for provision of a navigation service in more than one Member State. b) If one Member State issues a NOTAM affecting FIRs in a group of Member States, the first two letters of the ICAO location indicator of the issuing Member State plus ‘XX’ shall be included. The location indicators of the FIRs concerned shall then be listed in Item A or the indicator of the Member State or the delegated entity which is responsible for provision of a navigation service in more than one Member State.

2.NOTAM CODE All NOTAM Code groups contain a total of five letters, the first of which is always the letter ‘Q’. The second and third letters identify the subject, and the fourth and fifth letters denote the status or condition of the subject reported upon. The two-letter codes for subjects and conditions are those contained in ICAO Doc 8400 ‘Procedures for Air Navigation Services – ICAO Abbreviations and Codes (PANS-ABC)’. For combinations of second and third, and fourth and fifth letters, refer to the ‘NOTAM Selection Criteria’ contained in ICAO Doc 8126 or insert one of the following combinations, as appropriate: a) if the subject is not listed in the NOTAM Code (ICAO Doc 8400) or in the NOTAM Selection Criteria (ICAO Doc 8126), insert ‘XX’ as the second and third letters (e.g. QXXAK); if the subject is ‘XX’, use ‘XX’ also for condition (e.g. QXXXX). b) if the condition of the subject is not listed in the NOTAM Code (ICAO Doc 8400) or in the NOTAM Selection Criteria (ICAO Doc 8126), insert ‘XX’ as the fourth and fifth letters (e.g. QFAXX); c) when a NOTAM containing operationally significant information is issued and when it is used to announce the existence of AIRAC AIP Amendments or Supplements, insert ‘TT’ as the fourth and fifth letters of the NOTAM Code; d) when a NOTAM is issued containing a checklist of valid NOTAM, insert ‘KKKK’ as the second, third, fourth and fifth letters; and e) the following fourth and fifth letters of the NOTAM Code shall be used in NOTAM cancellations: AK = RESUMED NORMAL OPERATION AL = OPERATIVE (OR RE-OPERATIVE) SUBJECT TO PREVIOUSLY PUBLISHED LIMITATIONS/CONDITIONS AO = OPERATIONAL CC = COMPLETED CN = CANCELLED HV = WORK COMPLETED XX = PLAIN LANGUAGE As Q – - AO = Operational shall be used for NOTAM cancellation and NOTAM promulgating new equipment or services, use the following fourth and fifth letters Q – - CS = Installed. Q – - CN = CANCELLED shall be used to cancel planned activities, e.g. navigation warnings; Q – - HV = WORK COMPLETED shall be used to cancel work in progress.

3.TRAFFIC I = IFR V = VFR K = NOTAM is a checklist Depending on the NOTAM subject and content, the qualifier field TRAFFIC may contain combined qualifiers.

4.PURPOSE N = NOTAM selected for the immediate attention of flight crew members B = NOTAM of operational significance selected for PIB entry O = NOTAM concerning flight operations M = Miscellaneous NOTAM; not subject for a briefing, but available on request K = NOTAM is a checklist Depending on the NOTAM subject and content, the qualifier field PURPOSE may contain the combined qualifiers BO or NBO.

5.SCOPE

A = Aerodrome E = En-route W = Nav Warning K = NOTAM is a checklist Depending on the NOTAM subject and content, the qualifier field SCOPE may contain combined qualifiers.

6.and 7. LOWER/UPPER LOWER and UPPER limits shall only be expressed in flight levels (FL) and shall express the actual vertical limits of the area of influence without the addition of buffers. In the case of navigation warnings and airspace restrictions, values entered shall be consistent with those provided under Items F and G. If the subject does not contain specific height information, insert ‘000’ for LOWER and ‘999’ for UPPER as default values.

8.COORDINATES, RADIUS The latitude and longitude accurate to one minute, as well as a three-digit distance figure giving the radius of influence in NM (e.g. 4700N01140E043). Coordinates present the approximate centre of circle whose radius encompasses the whole area of influence, and if the NOTAM affects the entire FIR/UIR or more than one FIR/UIR, enter the default value ‘999’ for radius.

4.Item A Insert the ICAO location indicator as contained in ICAO Doc 7910 of the aerodrome or FIR in which the facility, airspace, or condition being reported on is located. More than one FIR/UIR may be indicated, when appropriate. If there is no available ICAO location indicator, use the ICAO nationality letter as given in ICAO Doc 7910, Part 2, plus ‘XX’ and followed up in Item E by the name, in plain language. If information concerns GNSS, insert the appropriate ICAO location indicator allocated for a GNSS element or the common location indicator allocated for all elements of the GNSS (except GBAS). In the case of GNSS, the location indicator may be used when identifying a GNSS element outage such as KNMH for a GPS satellite outage.

5.Item B For date-time group, use a ten-figure group, giving year, month, day, hours and minutes in UTC. This entry is the date-time at which the NOTAMN comes into force. In the cases of NOTAMR and NOTAMC, the date-time group is the actual date and time of the NOTAM origination. The start of a day shall be indicated by ‘0000’.

6.Item C With the exception of NOTAMC, a date-time group (a ten-figure group giving year, month, day, hours and minutes in UTC) indicating duration of information shall be used unless the information is of a permanent nature in which case the abbreviation ‘PERM’ is inserted instead. The end of a day shall be indicated by ‘2359’, ‘2400’ shall not be used. If the information on timing is uncertain, the approximate duration shall be indicated using a date-time group followed by the abbreviation ‘EST’. Any NOTAM which includes an ‘EST’ shall be cancelled or replaced before the date-time specified in Item C.

7.Item D If the hazard, status of operation or condition of facilities being reported on will be active in accordance with a specific time and date schedule between the dates-times indicated in Items B and C, insert such information under Item D. If Item D exceeds 200 characters, consideration shall be given to providing such information in a separate, consecutive NOTAM.

8.Item E Use decoded NOTAM Code complemented, where necessary, by ICAO abbreviations, indicators, identifiers, designators, call signs, frequencies, figures and plain language. When NOTAM is selected for international distribution, English text shall be included for those parts expressed in plain language. This entry shall be clear and concise in order to provide a suitable PIB entry. In the case of NOTAMC, a subject reference and status message shall be included to enable accurate plausibility checks.

9.Items F and G These items are normally applicable to navigation warnings or airspace restrictions and are usually part of the PIB entry. Insert both lower and upper height limits of activities or restrictions, clearly indicating only one reference datum and unit of measurement. The abbreviations ‘GND’ or ‘SFC’ shall be used in Item F to designate ‘ground’ and ‘surface’ respectively. The abbreviation ‘UNL’ shall be used in Item G to designate ‘unlimited’.
