GM1 ATM/ANS.OR.A.045(f) Changes to a functional system

ED Decision 2017/001/R

LACK OF COORDINATION

(a)     If an aviation undertaking decides not to cooperate, the service provider, who has identified dependencies with the aviation undertaking, in accordance with ATM/ANS.OR.A.045(e)(1), needs to consider the impact of having the assumptions and risk mitigations not agreed with that aviation undertaking. It should propose a way forward by doing one or more of the following:

(1)     making the assumptions themselves and providing evidence that supports them;

(2)     adding additional mitigating measures so that the change remains acceptably safe;

(3)     modifying the scope of the change, or even reconsidering and cancelling the change.

(b)     The service provider affected by a lack of cooperation with an aviation undertaking may wish to inform its competent authority about those aviation undertakings that are not participating and its form of non-participation, in order to seek the assistance of the competent authority in trying to persuade the aviation undertaking to participate.
