25、60-004:2011EN 4660-004:2011 (E) 5 0 Introduction 0.1 Purpose This document is produced under contract ASAAC Phase II Contract n97/86.028. 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

26、) 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.

27、 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 im

28、plementation through application of the standards. The document hierarchy is given hereafter: (in this figure the document is highlighted) Guidelines for System Issues System Management Fault Management Initialisation / Shutdown Configuration / Reconfiguration Time Management Security Safety Standar

30、Clause 1, Scope. Clause 2, Normative references. Clause 3, Terms, definitions and abbreviation. Clause 4, Generic module specification. Clause 5, Module Mechanical Tests. Clause 6, Guidelines for a rack slot. Clause 7, Typical modular avionics environment. 1 Scope The purpose of this standard is to

31、establish uniform requirements for Packaging for the Common Functional Modules (CFM) within an Integrated Modular Avionic (IMA) system, as defined per ASAAC. It comprises the module physical properties and the Module Physical Interface (MPI) definitions together with guidelines for IMA rack and the

32、operational environment. The characteristics addressed by the Packaging Standard are: Interchangeability: For a given cooling method all modules conforming to the packaging standard will function correctly when inserted into any rack slot conforming to the standard for the cooling method. All module

33、s conforming to the Module Physical Interface (MPI) definitions for connector, IED and cooling interface will function correctly when inserted into any rack slot conforming to the same MPI definition. Maintainability: All modules are easily removable at first line. No special tools required at first

34、 line. No manual adjustment is necessary when installing modules. No tool is required for installation or removal of the modules. Mechanical keying is provided that prevents insertion of a module into a rack slot that may cause an unsafe condition. The Module Physical Interface definition, contained

35、 within this standard, does not include the properties of the signalling used in the optical interface (e.g. wavelength). These are covered in EN 4660-003.
