Yaw damper issue in FS2004

[EHM-1388 Tiberiu]

I've just installed FS2004 and I noticed the Yaw Damper doesn't work... so I did a little research and I found a document describing how to fix this:

In the Aircraft.cfg file, find the [autopilot] section and change the value like this:

yaw_damper_gain=1.000000

Thanks to José Antonio Moreno for solving this.
