9. Aeronautical information products and services

The ATS provider should, together with the aerodrome operator, perform an analysis of the aeronautical information affected by the introduction of remote aerodrome ATS and ensure that relevant aeronautical information is included in the appropriate products and services, as stipulated in the relevant requirements in Annex IV ‘Part-ATS’ and Annex VI ‘Part-AIS’ to Regulation 2017/373 [4]. With regard to the publication of the aeronautical information, general requirements are laid down in AIS.TR.305, while the AIP content and structure are established in Appendix 1 to Annex VI ‘Part-AIS’. Section AD 2.23 of the AIP structure determines the elements of information to be published for each of the aerodromes at which ATS is provided remotely. They include: indication that remote aerodrome ATS is provided; location of the signalling lamp by e.g. the phrase ‘signalling lamp positioned at [geographical fix]’ as well as a clear indication of the signalling lamp location in the aerodrome chart for each relevant aerodrome; description of any specific communication methods as deemed necessary in the case of multiple mode of operation, such as e.g. the inclusion of airport names/ATS unit call sign for all transmissions (i.e. not only for the first contact) between pilots and ATCOs/AFISOs; description of any relevant actions required by the airspace users following an emergency/abnormal situation and possible contingency measures by the ATS provider in case of disruptions, if applicable (see AD 2.22 ‘Flight procedures’ of the AIP structure); and description of the interdependencies of service availability or indication of aerodromes not suitable for diversion from the aerodrome […..] if deemed applicable. Furthermore, indication that ATS is remotely provided should be included in all approach charts of aerodromes where ATS is remotely provided, with reference to the information listed above. To facilitate this, the provisions of ICAO Annex 4 apply. Annex 4 does not foresee the inclusion of similar information in the approach charts, but it does allow the inclusion of additional symbols on the chart: ‘Symbols used shall conform to those shown in Appendix 2 — ICAO Chart Symbols, except that where it is desired to show on an aeronautical chart special features or items of importance to civil aviation for which no ICAO symbol is at present provided, any appropriate symbol may be chosen for this purpose, provided that it does not cause confusion with any existing ICAO chart symbol or impair the legibility of the chart.’ Also in 2.3.3 of Annex 4 it is stipulated that ‘A legend to the symbols and abbreviations used shall be provided. The legend shall be on the face or reverse of each chart except that, where it is impracticable for reasons of space, a legend may be published separately.’ Another solution could be to use an abbreviation as they are allowed to be used — see ‘2.9.1 Abbreviations shall be used on aeronautical charts whenever they are appropriate.’ This information should not only be provided in the AIP. Other flight preparation sources should be used, as appropriate. This information should be provided in the AIP. Other flight preparation sources may be used, as appropriate. Information on implementation plans and milestones may be published in the aeronautical information circular (AIC). For instance, dates and scope of validation exercises, and planned date of operation.
