Hey guys, thanks for your comments thus far.
To Dan; after reaching that ~385ish limit and the Sidestick Deflection No longer having input, Will the airplane Pitch you upwards if you say Had power in so that you can't keep accelerating?.
To John; I hold a PPL, I fly 172's and Generally speaking The only Time i've ever pushed the yellow Bar is in Unusual Attitude Maneuvors with an instructor - and its because he's put me there, in times of Moderate turbulence I slow down to around Maneuvering speed, and on final Approach I like to hold 65+5 up untill landing is assured. While I understand that the number of people who come through these forums, Some of which are Utter Morons like everything in life. My intentions are purely technical for the thread - I'd never be interested in doing this with a Real A320, and your concern is taken in stride =]
