I will "second" what SonicBum said. From a pilot perspective, be wary of studying outside "engineering" material / tech ops stuff as your job is to fly it, respond to malfunctions per the ECAM, QRH, and SOPs, and not be a test pilot or diagnose stuff. That is how Airbus wants you do it. Yes, understand "why" a light or abnormal happened, but not much beyond that.
