I have A320 PIC and while it is one of the most technically correct packages I have seen, make sure you have a high-end computer to run it on - she's a serious frame-eater! Other than that, the lack of an in-depth manual is dissapointing. Although, I have a great manual which I can email to you.
Basically, if you have a top-end system (i.e P4 or AMD XP
> 2400, 512MB RAM and a good graphics card) and enjoy a more technically challenging flight (setting up the cockpit is great fun - full working FMC) - then A320 PIC is probably for you. I think their is also another A320 program out - called A320 Professional - apparently this add-on isn't such a drain on your system.
If you have any more queries, I'd be more than willing to answer them.
Drop me a line if you want.
