EVS-EN 4660-003:2019

The purpose of this MOAA standard is to define a set of open architecture standards, concepts & guidelines for Advanced Avionics Architectures (A3).
The three main goals for the MOAA Standards are:
— Reduced life cycle costs,
— Improved mission performance,
— Improved operational performance.
The MOAA 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.
The document hierarchy is given in Figure 1: (in this figure the document is highlighted).
