Hi all,
Apologies if this has been mentioned before, I did do a search...
Anyway last week we were on an EZY A319 from Gatwick. Whilst on the ground (and I'm not sure at what point this sound started, maybe whilst pushing back), there was a fast intermittent whirring sound. It sounded like something was moving forwards and backwards, and continued for a good few seconds.
I assumed it was some sort of ballast / CoG device moving into position - not that I'm even sure there is such a thing on aircraft.
Can someone tell me what this is please?
Thanks
Andoni
