Bolty incorrect.....the system still goes belly up on the A330 and it seems only when the aircraft has a full load.................seems like the system cant handle too much demand at the same time.................I personally have had collins and rockwell meet the aircraft to acess the probs on the flight and they are at a loss......................it is just not able to cope with a full load of pax.........................this has been the case from day one and they still dont know what to do.......i believe that QF is getting huge compensation for it not working that is why they are onto the CSMs logging each defect
