6 replacement sounds for the cockpit background sounds. 

1. Unzip the cockpit sounds folder.
2. Double click to play each sound in the unzipped cockpit sounds folder.
3. If there is one that you like, open your Aircraft/sounds folder. For FS9, you have to open the FS9 root directory/sounds folder - the folder where all your default FS9 sounds are stored.
4. Locate your existing cockpit sound wav file [you might have to play them all!]. Note its name.
5. Rename your existing cockpit.wav file to original_cockpit.wav and move it to your desktop or disc.
6. Rename the new cockpit sound [the one that you liked in para3] to the name in para 4.
7. Move the renamed new cockpit.wav file into your Aircraft/sounds folder or FS9 root directory/sounds folder.
8. To reverse this, rename the original_cockpit.wav file [the one on your desktop or disc] to the name in para 4. Locate the file with the same name in your FS9 root directory/sounds folder and delete it. Replace it with the one from your desktop or disc.
9. I hope that one is suitable for you.
