Abstract: The present invention relates to a distributed avionics system (100, 500) having a plurality of computer nodes arranged to execute a plurality of partitions/applications (P1, P2, P3, P4, P5, P6). The distributed avionics system comprises reconfiguration means (332) arranged to reconfigure the distributed avionics system upon detection of failure in at least one of the computer nodes. Each partition/application is associated to a application/partition availability level. The reconfiguration means are arranged to reconfigure the distributed avionics system based on the partition/application availability levels of the partition/applications (P1, P2, P3, P4, P5, P6). The present invention further relates to a method for back-up handling in a distributed avionics system having a plurality of computer nodes (A, B, C).

Abstract: The invention pertains to a configurable input/output processing device, a method for configuring the configurable input/output processing device and a computer program product for performing the steps of the method. The configurable input/output processing device (6) is arranged to control data traffic associated to a distributed avionics control system comprising a plurality of processing nodes interconnected in a network (2), wherein each of the plurality of processing nodes is connected to the network via at least one of said configurable input/output processing device. The configurable input/output processor comprise first instructions (CCR), said first instructions comprising processing information for the at least one input/output processing device and being independent of a current configuration of the distributed avionics control system and second instructions (SCT), said second instructions being dependent on the current configuration of the distributed avionics control system.
