BS EN 4660-002:2011

What is BS EN 4660-002 - Common Functional Module (CFM) about?

BS EN 4660 is a European standard that discusses modular and open avionics architectures.

BS EN 4660-002 is the second part of a multi-part series that defines the functionality and principal interfaces for the Common Functional Module (CFM) to ensure the interoperability of Common Functional Modules and provides design guidelines to assist in the implementation of such a CFM. It is one of a set of standards that define an ASAAC (Allied Standard Avionics Architecture Council) Integrated Modular Avionics System.

This definition of interfaces and functionality allows a CFM design that is interoperable with all other CFM to BS EN 4660-002, that is technology transparent, that is open to a multi-vendor market and that can make the best use of COTS technologies.

Although the physical organization and implementation of a CFM should remain the manufacturer’s choice, following the best use of the current technology, it is necessary to define a structure for each CFM to achieve a logical definition of the CFM with defined functionality. This definition includes:

• The Generic CFM defines the generic functionality applicable to the complete set of CFMs. The generic functionality is defined in 4.1
• The processing capability defines the unique functionality associated with each CFM type within the set. This functionality is defined in 4.3
• The logical and physical interfaces that enable CFMs to be interoperable and interchangeable, are defined in Clause 6
• The functionality required by a CFM to support the operation of the System is defined in Clause 6

Who is BS EN 4660-002 - Common Functional Module (CFM) for?

BS EN 4660-002 on Common Functional Module (CFM) is useful for:

•  Manufacturers of aircraft and spacecraft
• Integrated modular avionics system manufacturers
• Aeronautical engineers
• Astronautical engineers

Why should you use BS EN 4660-002 - Common Functional Module (CFM)?

Function modules are ABAP routines that encapsulate program code and provide an interface for data exchange and that are stored in a central function library.

BS EN 4660-002 provides you with CFM definition and common functional module interfaces like module logical interface (MLI), module physical interface (MPI) and MOS interface.

BS EN 4660-002 provides the best industry guidelines on CFM system support regarding fault management, fault detection, fault-masking, fault confinement and safety and security.

BS EN 4660-002 assists in establishing well-defined interfaces and functionality, a network design that is technology transparent and that is open to a multi-vendor market.

With compliance and obedience to the BS EN 4660-002 guidelines, you can reduce lifecycle costs, improve mission performance, and improve operational performance.
