Air Traffic Management - Specification for Software Assurance Levels; German and English version CEN/TS 16501:2013
Flugverkehrsmanagement - Spezifikation für Software-Sicherheitsanforderungsstufen; Deutsche und Englische Fassung CEN/TS 16501:2013
The European Union launched the "Single European Sky" (SES) Legislation in 2002, which was adopted in 2004. The SES legislation is based on a framework of four regulations. One of these is the Interoperability Regulation (EC 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 more safety-critical. It is therefore necessary to define guidance on how to standardise the assurances that may be provided for software. Technical Committee CEN/TC 377 "Air Traffic Management" published draft prEN 16154 "Air Traffic Management - Software assurance levels". After the conclusion of the public consultation phase CEN/TC 377 decided to waive the disclosure of the document as a standard and to publish the working result within the framework of a CEN/TS. Changing the publication form required a change of the document number and title of the present CEN/TS 16501 "Air Traffic Management - Software assurance levels" which is now available in German. This Technical Specification specifies the technical, operational and maintenance requirements for Software Assurance 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) No. 552/2004 of the European Parliament and of the Council on the interoperability of the European Air Traffic 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 software 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 compliance with the present document. This document (CEN/TS 16501:2013) has been prepared by Technical Committee CEN/TC 377 "Air Traffic Management", the secretariat of which is held by DIN (Germany) , with the participation of German experts of the Aerospace Standards Committee. The responsible German standardization committee is Working Committee NA 131-05-02 AA "Flugverkehrsmanagement (ATM)" ("Air traffic management (ATM)") at the Aerospace Standards Committee (NL) at DIN.
