Interactive A320 flight deck, can click on any panel/button/FMS etc to get a more detailed view and explanation of its function.
Hope this helps ......
(PS : I have seen an A320 Sim in PCworld ......comes boxed with a flight deck video ...... don't know what its like ...).
BTW : I fly Airbus ...... treat the stick like it has 'crap' on it ...... its very easy to over control, the a/c will self trim and is very sensitive. Select an attitude and bank and dont touch the stick until you need to change that.
Its a very easy a/c to fly if you don't overcontrol.
Good luck.
