Aerospace series - Modular and Open Avionics Architectures - Part 004: Packaging

This European standard establishes uniform requirements for Packaging for the Common Functional
Modules (CFM) within an Integrated Modular Avionic (IMA) system. It comprises the module physical
properties and the Module Physical Interface (MPI) definitions together with guidelines for IMA rack
and the 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 modules 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 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 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.

Luft- und Raumfahrt - Modulare und offene Avionikarchitekturen - Teil 004: Paketierung

Diese Europäische Norm legt einheitliche Anforderungen an die Paketierung der Standardfunktionsmodule (CFM) innerhalb eines Integrierten Modularen Avionik-Systems (en: Integrated Modular Avionic, IMA) fest. Dieses Dokument umfasst die physischen Moduleigenschaften und die Definitionen der physischen Modulschnittstelle (MPI) sowie Leit¬linien zum IMA-Gestell und zur Betriebsumgebung.
Der Paketierungsstandard behandelt die folgenden Merkmale:
Austauschbarkeit:
   Bei einem gegebenen Kühlverfahren funktionieren alle dem Paketierungsstandard entsprechenden Module ordnungsgemäß, wenn sie in einen beliebigen Gestellsteckplatz eingesetzt sind, der dem für das Kühlverfahren geltenden Standard entspricht.
   Alle den MPI-Definitionen für Steckverbinder, IED und Kühlschnittstelle entsprechenden Module funk-tionieren ordnungsgemäß, wenn sie in einen beliebigen Gestellsteckplatz eingesetzt sind, der derselben MPI-Definition entspricht.
Instandhaltbarkeit:
   Alle Module sind vor Ort leicht auszubauen.
   Vor Ort sind keine speziellen Werkzeuge erforderlich.
   Beim Einbau von Modulen ist keine manuelle Anpassung notwendig. Zum Ein  und Ausbau der Module ist kein Werkzeug erforderlich.
   Es ist eine mechanische Verstecksicherung vorgesehen, die verhindert, dass das Modul in einen Steck-platz eingesetzt wird, der möglicherweise einen unsicheren Zustand bewirkt.
Die in dieser Norm enthaltene Definition der physischen Modulschnittstelle umfasst nicht die Signalisie-rungseigenschaften der optischen Schnittstelle (z. B. die Wellenlänge). Diese werden von EN 4660 003 abgedeckt.

Aeronavtika - Modularne in odprte letalske elektronske arhitekture - 004. del: Pakiranje

Ta evropski standard določa enotne zahteve glede pakiranja za skupne funkcijske module (CFM) znotraj integriranega modularnega letalskega sistema (IMA). Vključuje fizične lastnosti modula in definicije fizičnega vmesnika modula (MPI) s smernicami za stojalo IMA in delovno okolje.
Značilnosti, ki jih zajema standard za pakiranje:
Medsebojna zamenljivost:
 Za določen način hlajenja bodo vsi moduli, ki so skladni s standardom za pakiranje, ob vstavitvi v katero koli režo stojala, ki je skladno s standardom za način hlajenja, delovali pravilno.
 Vsi moduli, ki so skladni z definicijami fizičnega vmesnika modula (MPI) za konektor, IED in hladilni vmesnik, bodo ob vstavitvi v katero koli režo stojala, ki je skladno z isto definicijo vmesnika MPI, delovali pravilno.
Primernost za vzdrževanje:
 Vse module v prvi vrsti je mogoče preprosto odstraniti.
 Za prvo vrsto niso potrebna nobena posebna orodja.
 Ročne prilagoditve pri namestitvi modulov niso potrebne. Za namestitev ali odstranitev modulov ni potrebno nobeno orodje.
 Na voljo je mehansko kodiranje, ki preprečuje vstavitev modula v režo stojala, ki bi povzročila nevaren pogoj.
Definicija fizičnega vmesnika modula, ki jo vsebuje ta standard, ne vključuje lastnosti signalizacije, uporabljene pri optičnih vmesnikih (npr. valovna dolžina). Te so obravnavane v standardu EN 4660-003.

Introduction
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 hereafter: (in this figure the document is highlighted).
