ED Decision 2020/008/R

NOTAM

(a) The predetermined distribution system provides for incoming NOTAM (including SNOWTAM and ASHTAM) to be channelled through the aeronautical fixed service (AFS) directly to designated addressees predetermined by the receiving country concerned while concurrently being routed to the international NOTAM office for checking and control purposes.

(b) The addressee indicators for those designated addressees are constituted as follows:

(1) First and second letters

 The first two letters of the location indicator for the AFS communication centre associated with the relevant international NOTAM office of the receiving country.

(2) Third and fourth letters

  The letters ‘ZZ’ indicating a requirement for special distribution.

(3) Fifth letter

  The fifth letter differentiating between NOTAM (letter ‘N’), SNOWTAM (letter ‘S’), and ASHTAM (letter ‘V’).

(4) Sixth and seventh letters

  The sixth and seventh letters, each taken from the series A to Z, denoting the national and/or international distribution list(s) to be used by the receiving AFS centre.

  The fifth, sixth and seventh letters replace the three-letter designator YNY which, in the normal distribution system, denotes an international NOTAM office.

(5) Eighth letter

  The eighth position letter shall be the filler letter ‘X’ to complete the eight-letter addressee indicator.

(c) Member States are to inform the States from which they receive NOTAM of the sixth and seventh letters to be used under different circumstances to ensure proper routing.

AIS.TR.405 Pre-flight information services

Commission Implementing Regulation (EU) 2020/469

(a) Automated pre-flight information systems shall be used to make aeronautical data and aeronautical information available to operations personnel, including flight crew members, for self-briefing, flight planning and flight information service purposes.

(b) The human machine interface of the pre-flight information services facilities shall ensure easy access to all relevant information/data in a guided manner.

(c) Self-briefing facilities of an automated pre-flight information system shall provide access, as necessary, to the aeronautical information service for consultation by telephone or other suitable telecommunication means.

(d) Automated pre-flight information systems for the supply of aeronautical data and aeronautical information for self-briefing, flight planning and flight information service shall:

(1) provide for continuous and timely updating of the system database and monitoring of the validity and quality of the aeronautical data stored;

(2) permit access to the system by operations personnel, including flight crew members, aeronautical personnel concerned and other aeronautical users, through suitable telecommunications means;

(3) ensure the provision of the aeronautical data and aeronautical information accessed, in paper form, as required;

(4) use access and interrogation procedures based on abbreviated plain language and ICAO location indicators laid down in ICAO Doc 7910, as appropriate, or based on a menu-driven user interface or other appropriate mechanism;

(5) provide a timely response to a user request for information.

(e) All NOTAM shall be made available for briefing by default, and content reduction shall be at user’s discretion.

AUTOMATION

(a) Automated pre-flight information systems that provide a harmonised, common point of access by operations personnel, including flight crew members and other aeronautical personnel concerned, to aeronautical information and meteorological information should be established by an agreement between the AIS provider and the meteorological services provider.

(b) Where automated pre-flight information systems are used to provide the harmonised, common point of access by operations personnel, including flight crew members and other aeronautical personnel concerned, to aeronautical data, aeronautical information and meteorological information, the AIS provider remains responsible for the quality and timeliness of the aeronautical data and aeronautical information provided by means of such a system. 

(c) The meteorological services provider concerned remains responsible for the quality of the meteorological information provided by means of such a system in accordance with Annex V to Regulation (EU) 2017/373.
