6.2.6 Voice-ATIS shall not be provided on an ILS facility (248).
6.2.7 Voice-ATIS broadcasts, when provided, shall be continuous and repetitive (249).
Guidance: In the event of failure of the Voice-ATIS, the air traffic controller may provide the ATIS information using the control VHF frequency or, where the workload prevents this, by opening of another alternative VHF frequency by an additional air traffic controller or assistant.
6.3 D-ATIS
6.3.1 Where D-ATIS is provided alongside the existing availability of Voice-ATIS, the content and format of the information shall be identical (250).
6.3.2 Where D-ATIS is provided alongside the existing availability of Voice-ATIS, when the ATIS requires updating, the Voice-ATIS and D-ATIS shall be updated simultaneously (251).
6.3.3 Where D-ATIS broadcast includes real time meteorological information, which is within the parameters of the significant change criteria reference [3], the content shall be considered identical for the purpose of maintaining the same designator (252).
Guidance: In the event of failure of the D-ATIS, the ATIS information can be obtained from the Voice-ATIS. Where both D-ATIS and Voice-ATIS fail, the situation is the same as that for a failure of the Voice-ATIS.
It is likely that interface arrangements will need to be established between the Air Traffic Service Providers, operating the aerodrome Voice-ATIS, and the D-ATIS data link Service Provider, to ensure compliance with the requirements of paragraphs 6.3.1 to 6.3.3, which are based on ICAO SARPS.
NOTE: Guidance material relating to D-ATIS is contained in the document cited at paragraph 3 reference [5]. The technical requirements for the D-ATIS application are contained in Part 1 Chapter 3 of ICAO Annex 10 Vol III, see paragraph 3 reference [2].
6.4 Collation of Meteorological and Aerodrome Data
6.4.1 The meteorological data used in the preparation of ATIS messages shall be compliant with ICAO Annex 3 (253).
6.4.2 The meteorological data shall be extracted from the local meteorological routine or special report (254).
6.4.3 Where rapidly changing meteorological conditions preclude the inclusion of a weather report, the ATIS message shall contain information that the relevant weather information will be given on initial contact with the Air Traffic Control Unit (255).
6.4.4 The Air Traffic Service Provider shall ensure that the accuracy and integrity of the data used in the preparation of the ATIS message is maintained at a level appropriate to the operational requirements (256).
Guidance: It is likely that the interface arrangements between the Air Traffic Service Provider and the Data Link Communications Service Provider will enable the Air Traffic Service Provider to obtain evidence of compliance with this requirement for the Data Link operations.
6.5 Preparation of Messages
6.5.1 Where the Voice-ATIS broadcast messages are not prepared by the aerodrome ATC Unit, the organisation responsible for this task shall immediately make known the information contained in the current broadcast to the ATC Unit (257).
6.5.2 Voice-ATIS broadcasts shall be prepared in the English language (258).
6.5.3 Recommendation: The Voice-ATIS broadcast should be prepared to achieve optimum readability consistent with message length, speed of transmission and human factors performance (259).
Guidance: The message length should not exceed 30 seconds.
6.5.4 Recommendation: The message contents should be kept as brief as possible and information additional to that specified in ICAO Annex 11, 4.3.7. to 4.3.9 should only be included in exceptional circumstances (260).
6.5.5 The message contents shall contain the elements of information as defined in ICAO Annex 11, 4.3.7. to 4.3.9 in the order given (261). NOTE: The Appendix to COM 05 contains a summary of the ATIS message
