METHOD AND SYSTEM FOR DEVELOPING A NEW VERSION OF SOFTWARE OF AN AVIONICS COMPUTER

摘要

An aircraft avionics computer is equipped with a current software version comprising a set of interconnected functions. A function to be updated of the set of functions, receives, as input, function outputs of a first subset of functions of the set of functions and provides an output linked to a first input of a switch. Developing a new version of the avionics computer software comprises connecting to the avionics computer an external computer of which software comprises a new version of the function to be updated; receiving, by the new function version, function outputs of the first subset of functions; dispatching the output of the function to be updated to a second switch input; controlling the switch such that in a normal mode of operation, the switch output corresponds to the first input and in a fine-tuning mode of operation, the switch output corresponds to the second input.
