A320 electrical problems
Was involved in one of these incidents a few years ago in Tel Aviv. A/c was almost at V1 when it lost 4 out of six CDU's. Then the Master warnings went off but with no upper or lower Ecam and F/Os side dead no idea of what the failure was. Bearing in mind most ECAMS are inhibited for take off it had to be serious. The crew opted for aborting the T/O which resulted in four u/s brakes and four blown tyres due thermal overheat.
Similar hapened a couple of weeks later at 10Kft in descent to BFS. This resulted in a/c being grounded and replacement of generator after which all was well
