The Airbus A320 is my favorite commercial aircraft. After months of searching for the perfect one for FS2002, I came upon this site.

Project Airbus is a site that features a varitety of Airbus aircraft including their wonderful A320. Aircraft are well done and come with complete and functional virtual cockpit and reflective textures. Not many downloads available at their site all aircraft and projects are listed. Available aircraft can be downloaded at Avsim.

Project Airbus' A320 CFM sound pack is also a must download. As I'm sure most people who have flown on the A320 know, the aircraft has it's own unique, sort of humming/grinding sound to the engines. Sound clip recreates that to perfection. It's also available at Avsim.
