Folks,
With a modern aircraft and the multitude of electronic systems on board, what is the upgrade procedure? For example, would a new A320 have the same software and hardware as one of the first models did, even though the technology is now twenty years old? Would the displays on the flight deck be the same, or have they evolved over time? And if the software / hardware has changed, what is the certification stance? Presumably software upgrades would occur from time to time...how are these vaildated? Would the FAA / JAA etc. need to approve any upgrades? I would imagine that the manufacturers would upgrade technology between models eg. from A320 to 321 to 319 to 318 etc., as these new models need to be certified themselves anyway. But does this mean that the technology onboard a particular model lasts the lifetime of the model?
Thanks
