(2) the failures or anomalies of such automated coordination are presented clearly to the air traffic controller or controllers responsible for coordinating flights at a transferring unit; (3) the warnings related to system information exchange are presented to the relevant working positions; (4) the information about the relevant system information exchange processes is provided to the air traffic controllers; (5) air traffic controllers are provided with the means to modify the flight information exchanged.’; (d) the following point ATS.OR.446 is inserted:
‘ATS.OR.446 Surveillance data (a) Air traffic services providers shall not use data from Mode S interrogators that operate under the responsibility of a third country if the allocation of the interrogator code has not been coordinated.
(b) Air traffic services providers shall ensure that the necessary capabilities are implemented to allow air traffic controllers to establish individual aircraft identification using the downlinked aircraft identification feature, as detailed in Appendix 1. (c) Air traffic service providers shall ensure seamless operations within the airspace under their responsibility and at the boundary with adjacent airspaces by applying appropriate minimum requirements for the separation of aircraft.’; (e) in point ATS.TR.230, the following point (c) is added: ‘(c) The coordination of transfer of control between units that provide area control service within the ICAO EUR region, or when so agreed with or between other air traffic control units, shall be supported by automated processes as defined in Appendix 2.’; (f) the following Appendices 1 and 2 are added:
‘Appendix 1
Identification of individual aircraft using the downlinked aircraft identification feature as required by point ATS.OR.446(b) The downlinked aircraft identification feature shall be used as follows to establish individual aircraft identification: (a) The air traffic services provider shall declare to the Network Manager the airspace volumes where individual aircraft identification is established using the downlinked aircraft identification feature.
(b) The conspicuity SSR code A1000 shall be assigned to aircraft where individual aircraft identification is established by using the downlinked aircraft identification feature.
(c) Except when one of the conditions set out in point (d) apply, the conspicuity SSR code A1000 shall be assigned to departing aircraft or to aircraft for which, in accordance with point (g), a code change is required, where the following conditions apply: (1) the downlinked aircraft identification matches the corresponding entry in the flight plan for that aircraft; (2) the Network Manager has communicated that the particular aircraft is eligible for the assignment of the conspicuity SSR code A1000.
(d) The conspicuity SSR code A1000 shall not be assigned to aircraft referred to in point (c) if any of the following conditions apply: (1) contingency measures that require the assignment of discrete SSR codes to aircraft have been put in place by an air navigation service provider that experiences unplanned ground surveillance sensor outages;
