Apologies, Brian, I thought you were focussed merely on the pitching moment from the tailplane when you referred to 'unstable' (and obviously for that to occur the C of G would have to be aft of the tail.........). All agreed.
I believe this began as an AF447 topic, and apart from 'thesilver' this query has not really been addressed. IF the 330 design allows significantly reduced longitudinal stability RELYING on the FBW to assist the pilot ....answers on a postcard please, as JT says.
Now, anyone for canards.........................?
