Over the last ten years, both ANSPs and NSAs have made significant progress in implementing a systematic safety framework. Whilst ANSPs have applied safety management systems in accordance with ESARR 3 and Commission Regulation (EC) No 2096/2005, NSAs have been guided by ESARR 1 and Commission Regulation (EC) No 1315/2007 to implement their own requirements as to provide structured safety oversight.
