ED Decision 2019/022/R Software assurance level requirements for safety (support) assessment of changes to air traffic management/air navigation services functional systems

The objective of this Decision is to maintain a high level of safety by providing a set of harmonised software
assurance level (SWAL) measures for providers of air traffic management (ATM)/air navigation services (ANS)
and other ATM network functions when dealing with the (safety) assessment of changes to a functional system.
It thus aims at achieving a smooth transition into the new ATM/ANS regulatory framework.
This Decision amends ED Decision 2017/001/R with a set of acceptable means of compliance (AMC) and
guidance material (GM) for the definition and implementation of a software (safety) assurance system by
providers of ATM/ANS that is based on the requirements laid down in Regulation (EC) No 482/2008, which is
repealed by Regulation (EU) 2017/373.
The amendments are expected to maintain safety that has already be achieved with the implementation of
Regulation (EC) No 482/2008.
