scope:

The purpose of this European Standard is to establish uniform requirements for design and development of software architecture for modular avionics systems as defined per ASAAC.

Purpose

This document is produced under contract ASAAC Phase II Contract n°97/86.028.

The purpose of the ASAAC Programme is to define and validate a set of open architecture standards, concepts & guidelines for Advanced Avionics Architectures (A3) in order to meet the three main ASAAC drivers. The standards, concepts and guidelines produced by the Programme are to be applicable to both new aircraft and update programmes from 2005.

The three main goals for the ASAAC Programme are:

1. Reduced life cycle costs,

2. Improved mission performance,

3. Improved operational performance.

The ASAAC 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 system,

- The guidelines for system implementation through application of the standards.
