Erroneous Drift Diamond indications on A330
Having flown the 'bus for just a little while now & still missing the 767 track box I have noticed that the green' drift diamond' has been indicating erroneously on a few occasions.
By this I mean that the wind is straight down the runway - a/c tracking localiser without deviation, but 'drift diamond' indicates 3-4 degrees of drift.
Any thoughts from any of the Airbus guru's ?
