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
