Just before Christmas, when fog was plaguing London airports, I was flying from LHR to DUB and, as very good luck would have it, I got to fly on an Aer Lingus A330-200. Great. Lovely aircraft, great crew, nice flight.
However, as we were on finals to DUB, the gear came down; yes, of course, that's the right time to let the gear down ... but it was very audible, i.e. not quite a bang, but certainly an audible thud. I'm not sure if that was the gear doors opening or the actual bogies coming down and locking into place, but the passenger beside me - by no means a nervous flyer - did seem quite startled, and I reassured her that it was the gear.
I have noticed this on subsequent A330 flights (I flew DUB-SNN and back after Christmas) and the "gear down" seems more audible than on other Airbus types.
Anyone want to comment on this? In particular, what exact part of the "gear down" sequence is that "thud"?
