(c)Except as provided for in points AIS.TR.330(f) and AIS.TR.330(g), each NOTAM shall contain the information in the order shown in the NOTAM format of Appendix 2.

(d)NOTAM text shall be composed of the significations/uniform abbreviated phraseology assigned to the ICAO NOTAM Code, complemented by ICAO abbreviations, indicators, identifiers, designators, call signs, frequencies, figures and plain language.

(e)All NOTAM shall be issued in English language. If necessary for domestic users, NOTAM may additionally be issued in national language.

(f)Information concerning snow, slush, ice, frost, standing water or water associated with snow, slush, ice or frost on the movement area shall be disseminated by means of SNOWTAM and shall contain the information in the order shown in the SNOWTAM format of Appendix 3a. [applicable until 30 April 2025 - Regulation (EU) 2020/469]

(f)Information concerning snow, slush, ice, frost, standing water or water associated with snow, slush, ice or frost on the movement area shall be disseminated by means of SNOWTAM and shall contain the information in the order shown in the SNOWTAM format of Appendix 3. [applicable from 1 May 2025 - Regulation (EU) 2024/403]

(g)Information concerning an operationally significant change to volcanic activity, volcanic eruption and/or volcanic ash cloud shall, when reported by means of an ASHTAM, contain the information in the order shown in the ASHTAM format of Appendix 4.

(h)When errors occur in a NOTAM, a NOTAM with a new number shall be issued to replace the erroneous NOTAM or the erroneous NOTAM shall be cancelled and a new NOTAM shall be issued.

(i)When a NOTAM is issued that cancels or replaces a previous NOTAM:

(1)the series and number/year of the previous NOTAM shall be indicated;

(2)the series, location indicator and subject of both NOTAM shall be the same.

(j)Only one NOTAM shall be cancelled or replaced by a NOTAM.

(k)Each NOTAM shall deal with only one subject and one condition of the subject.

(l)Each NOTAM shall be as brief as possible and compiled so that its meaning is clear without the need to refer to another document.

(m)A NOTAM containing permanent or temporary information of long duration shall include appropriate references to the AIP or AIP supplement.

(n)Location indicators included in the text of a NOTAM shall be those contained in ICAO Doc 7910 ‘Location Indicators’. A curtailed form of such indicators shall not be used. Where no ICAO location indicator is assigned to the location, its place name shall be entered in plain language.

(o)A series identified by a letter and a four-digit number followed by a stroke and a two-digit number for the year shall be allocated to each NOTAM. The four-digit number shall be consecutive and based on the calendar year.

(p)All NOTAM shall be divided in series based on subject, traffic or location or a combination thereof, depending on end-user needs. NOTAM for aerodromes allowing international air traffic shall be issued in international NOTAM series.

(q)If NOTAM are issued in both English and national language, the NOTAM series shall be organised so that the national language series are equivalent to the English language series in terms of content and numbering.

(r)The content and geographical coverage of each NOTAM series shall be stated in detail in the AIP, in point GEN 3.

(s)A checklist of valid NOTAM shall be regularly provided.

(t)One checklist NOTAM shall be issued for each series.

(v)A checklist NOTAM shall have the same distribution as the actual message series to which it refers and shall be clearly identified as a checklist.

(w)Series allocation shall be monitored and, if required, appropriate measures shall be taken to assure that no series reaches the maximum possible number of issued NOTAM before the end of a calendar year.
