My quickie review of the Wilco/Feelthere A320s. I'm not a professional, nor am I a particular Airbus expert, but my 50 GB FS2004 installation does indicate that I am a bit of a payware junkie.
I can't quibble about the exterior modeling, some people have said there are issues but if there are, I don't notice. The interior looks pretty good. There is a VC and it's largely clickable, but I don't use it, as my old machine (Athlon XP 2500, 1 GB RAM, Geforce 6600 128 MB AGP) is barely up for running the Airbus in 2D, much less VC mode. The gauge refresh rate in VC mode isn't that great. Even sitting on a runway on a clear day, I can get as low as 12 fps. But, my system is a bit of an underperformer for whatever reason.
The fly-by-wire system on the Bus is modeled. Pull the nose up to, say, 10 degrees pitch and let it go, and the plane will maintain 10 degrees pitch as the speed changes. Similarly, the "notches" on the throttle are modeled, and you will hear click sounds as you move your throttle device up from idle, to flex, to climb, to TO/GA. You'll spend virtually the entire flight with your throttle sitting in the same place, and if your throttle device has calibration issues or spikes, it can mess with the autoflight system.
The autopilot is mostly or fully modeled to real-world spec. All the super-whiz Airbus automatic stuff is there, and the manual modes too.
The "Standard" package has the A318, A320, and A321. For whatever reason, Wilco decided to make the A319 and the A319CJ corporate jet part of the extra-cost "Deluxe" package. The A319 is pretty long-ranged for its size (I've done a 3300 nm flight with it, barely) and the A319CJ is longer-ranged still.
The original package was, as is typical with recent Feelthere offerings (the Legacy excluded), amazingly laden with bugs. They really rushed it out the door. There's been a couple of service packs since then and it's a lot better--it no longer routinely CTDs on me after a couple of hours.
