They also said that the A330 series computer system is susceptible to electro magnetic interference
I very much doubt that it is any more susceptible than other comparable aeroplane.
When the A330 was under consideration for the UK's Future Strategic Tanker Aircraft programme, one of my first queries was whether the susceptibility of the FBW system to EMI, for example caused by a receiver aircraft in close formation leaving its intercept radar on by mistake, had been considered. "Yes", I was told, "there is no issue".
Personally, I consider the EMI accident theory to be a roseate herring.
