A method of generating a customized secondary power distribution assembly (SPDA) includes generating one or more customizable SPDAs. Each of the one or more customizable SPDAs is a construct corresponding with a microprocessor configured to control a set of customizable channels in each of a set of virtual line replaceable modules (vLRMs). The method also includes creating a mapping between one of the one or more customizable SPDAs and the customized SPDA, the mapping indicating line replaceable modules (LRMs) of the customized SPDA and defining each channel of each LRM, and deploying the customized SPDA in an application. The microprocessor is initiated to control the customized SPDA according to the mapping at startup.

Customized secondary power distribution assembly generated from customizable secondary power distribution assembly

An assembly for an aircraft according to an example of the present disclosure includes, among other things, a control module including a processor and a local memory that stores a first instance of operational software executable by the processor and that relates to functionality of the control module to selectively control a vehicle system, and a backplane memory device coupled to the control module by a common backplane. The backplane memory device includes shadow memory that stores a second instance of the operational software. A method of synchronizing an assembly is also disclosed.

Software version synchronization for avionics systems

A power distribution assembly according to an example of the present disclosure includes, among other things, a housing at least partially receiving a plurality of hardware modules coupled to a backplane, the plurality of hardware modules including at least one output module and a communications module that communicates information between the plurality of hardware modules and a second power distribution assembly. At least one hardware module of the plurality of hardware modules includes a field programmable gate array that commands the at least one output module to selectively power at least one aircraft system. A method of operation of a power distribution system is also disclosed.
