FS2002 Airbus A320 CFM Sound. A high quality sound set for the A320 series aircraft with CFM56 engines. All new internal/external sounds in this package have been recorded from an A320 with CFM56 engines. Plenty of research work has been done to make this soundset sound as close as possible with the real thing, within the limits of FS2002. This sound set is fully optimized and was developed for use with the Project Airbus A320 with CFM56 engines. By Peter Binamira/Project Airbus.
