They were probably taxiing on one engine, and you were hearing the PTU pump

It's more than likely the Power Transefer Unit

That screwing sound makes me think the plane is not very sturdy. Not to bash airbus, but the engines on the A319 sound pretty whinny and pathetic as well. They sound like hair dryers.

I can't really understand yor comment. To me it seems like a usual "lets bash Airbus and their engines" comment.
Even if they were like "hair dryers" that would be a BIG advantage for Aribus and IAE for manufacturing silent engines !!!

|Quoting Kelebek (Reply 8):|
the terribles sound I ever notices is the gears-sound on a Canadair Reginal Jet. (OS operates some of them).
When they extend the gears before landing it does a crack that you think for a second the plane lost a wing or something like that. Terrible.
