Software assurance level requirements for safety assessment of changes to air traffic management/air navigation services functional systems

The objective of this NPA 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 NPA proposes a set of acceptable means of compliance (AMC)/guidance material (GM) for the definition and implementation of a software (safety) assurance system by providers of ATM/ANS and other ATM network functions that is based on the requirements laid down in Regulation (EC) No 482/2008, which is repealed by Regulation (EU) 2017/373.
