GM1 ATS.OR.205(a)(1) Safety assessment and assurance of changes to the functional system

ED Decision 2017/001/R

GENERAL

(a)     The safety assessment should be conducted by the air traffic services provider itself. It may also be carried out by another organisation, on its behalf, provided that the responsibility for the safety assessment remains with the air traffic services provider.

(b)     A safety assessment needs to be performed when a change affects a part of the functional system managed by the provider of air traffic services and that is being used in the provision of its (air traffic) services. The safety assessment or the way it is conducted does not depend on whether the change is a result of a business decision or a decision to improve safety.
