when the 330 first came out the a/thr was the pits. A change from a high to a low pressure system or even light turbulance would cause the a/thr to saw up and down and it was very uncomfortable to watch the racket it made. It would have the a/thr sawing form max power to trying to come back to idle! For the pax when they heard the pwr come off they though the engs had quit as when the pwr reduced the changes to the bleed sysytem and subsequently the air flow to the cabin was frightening. Airbus got on the case as people were flying the machine with no a/thr due its poor management. Today it is a different fish. Can you believe the a330 is around since late 93? I am sure sensible will have his own twist to the issue.
