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

摘要

In an avionic computer (12), a software function to be updated (Fs) receives at the input outputs (EF1 ... EFi) of functions of a first subset and provides an output connected to a first input (20a ) a switch (20). The method of developing a new version of the software comprises the following steps: - connecting to the avionics computer (12) an external computer (14) comprising a new version (Fs') of the function to be updated; - receive, by the new version of the function, the outputs of the functions of the first subset; - send the output (SF ') of the function to a second input (20b) of the switch (20); - control the switch (20) so that in a focus mode of operation, the output (Sc) of the switch corresponds to the second input (20b).
