Attention is drawn to the possibility that some of the elements of this document may be the subject of paten

The SES legislation is based on a framework of 4 regulations, which includes the Interoperability Regulation (E

18、C 552/2004). The objective of the Interoperability Regulation is to ensure interoperability of the European Air Traffic Management Network (EATMN) consistent with air navigation services. An increasing proportion of functions of the EATMN are implemented by software and these functions are becoming

19、more safety-critical. It is therefore necessary to define guidance on how to standardise the assurances that may be provided for software. PD CEN/TS 16501:2013CEN/TS 16501:2013 (E) 5 1 Scope This Technical Specification specifies the technical, operational and maintenance requirements for Software A

20、ssurance Levels to support the demonstration of compliance with some elements of the Essential Requirements “Safety” and “Principles governing the construction of systems” of the Regulation (EC 552/2004) of the European Parliament and of the Council on the interoperability of the European Air Traffi

21、c network (“the Interoperability regulation”). This Technical Specification on Software Assurance Levels (SWAL) is intended to apply to software that is part of the EATMN, focusing only on its “ground” segment and providing a reference against which stakeholders can assess their own practices for so

22、ftware specification, design, development, operation, maintenance, evolution and decommissioning. Requirements in the present document which refer to “should” statements or recommendations in the normatively referenced material are to be interpreted as fully normative (“shall”) for the purpose of co

23、mpliance with the present document. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the refe

24、renced document (including any amendments) applies.
