Abstract: The invention in particular has as an object a method and a device for reconfiguration of an avionic system comprising at least two computers and a software application, in an aircraft, each of the said computers being adapted for running the software application, the aircraft further comprising a module for detection of failure of at least one of the said computers as well as a loading module making it possible to load the software application into each of the computers. After an information item relating to the state of one of the computers has been received from the detection module, a failure of one of the computers is detected according to the information item received. A configuration according to which at least one application run by the faulty computer is run by another of the computers then is determined.
