What is BS EN 4660‑004 - Modular and open avionics architectures about?
BS EN 4660‑004 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 the IMA rack and the operational environment. The characteristics addressed by the BS EN 4660‑004 are:
Interchangeability:
- For a given cooling method all modules conforming to the BS EN 4660‑004 will function correctly when inserted into any rack slot conforming to the BS EN 4660‑004 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 the first line.
- No special tools are required at the first line.
- No manual adjustment is necessary when installing modules. No tool is required for the 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.
Note: The Module Physical Interface definition, contained within BS EN 4660‑004, does not include the properties of the signaling used in the optical interface (e. g. wavelength). These are covered in EN 4660-003.
Who is BS EN 4660‑004 - Modular and open avionics architectures for?
BS EN 4660‑004 on Modular and open avionics architectures are useful for:
- Avionics architecture developers
- Electrical equipment manufacturers
- Quality control laboratories
- Aerospace industry
Why should you use BS EN 4660‑004 - Modular and open avionics architectures?
The purpose of this BS EN 4660‑004 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 organized 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 the application of the standards.
BS EN 4660‑004 defines the mechanical tests that shall be carried out on a module built. This will help you improve the quality of your avionics.
