GM4 ATM/ANS.OR.A.045(e) Changes to a functional system ED Decision 2017/001/R COORDINATION WITH AFFECTED AVIATION UNDERTAKINGS (a) The aviation undertakings are the entities, persons or organisations as defined in point 34 of Annex I to [Regulation (EU) 2017/373](http://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32017R0373&from=EN) and thus, [ATM/ANS.OR.A.045(e)](#_DxCrossRefBm647742061) does not apply to them. However, any service provider affected by a change should seek the participation of aviation undertakings when assumptions and risk mitigations used in the safety (support) assessment are shared with those aviation undertakings. (b) When the number of aviation undertakings affected by the change is large, the service providers may not need to involve every individual stakeholder. If a body can represent the views of a group of affected aviation undertakings, it may suffice to involve that representative body to obtain the supporting evidence to move forward with the assessment of the change.
