DIN EN 4660-001:2011-07

The EN 4660 standard series has been prepared on the basis of the second phase of the ASAAC Programme (ASAAC Phase II Contract). The ASAAC is the Allied Standard Avionics Architecture Council which was founded with the aim to develop basics of modern avionics architecture. The purpose of the ASAAC Programme is to define and validate a set of open architecture standards, concepts and guidelines for Advanced Avionics Architectures (A3) in order to meet the three main drivers for the programme. The standards, concepts and guidelines produced by the Programme are to be applicable to both new aircraft and update programmes. The three main drivers for the ASAAC Programme are: - reduced life cycle costs; - improved mission performance; - improved operational performance. The standards are organised as a set of documents including: - a set of agreed standards that describe, using a top down approach, the architecture overview to all interfaces required to implement the core within avionics systems; - the guidelines for system implementation through application of the standards. The purpose of Part 001 of EN 4660 is to establish uniform requirements for the architecture for IMA systems as defined by the ASAAC Programme. The IMA architecture can be built by using common components. These components are specified in separate standards. Ways of using these components are described in a set of guidelines. This document gives references to these standards and guidelines as well as a short introduction to the concept of IMA. EN 4660-001:2011 has been prepared by ASD-STAN, Technical Section Electrics, Avionics, with the participation of German experts of the Aerospace Standards Committee. The European Committee for Standardization (CEN) declared the Aerospace and Defence Industries Association of Europe (ASD-STAN) responsible for the preparation of European standards (EN) for the field of aerospace. ASD became the associated body (ASB) of CEN by the agreement dated 1986-10-03. The responsible German standardization committee is Working Committee NA 131-04-09 AA "Avionik" ("Avionics") of the Aerospace Standards Committee at DIN.
