falcon102

Hi everyone,
I wanna know if anyone has informating about A/P yaw damper system. How does it work? and give me some pic with dawing the system, electrical "I mean." but if you can give me the electric servo yaw damper. you can find the Block diagram in book call "Avionics fundamentals" which made for Jeppesen sanderson Training Products. exaclty you can find in page 292.

Thanks a million

I have some stuff from Jeppesen, but not your reference.

I suggest you just look up negative feedback servo systems.
In this case the autopilot is likely hooked up to the gyrocompass and corrects rudder placement based on heading deviation. A more advanced system might use Loran or GPS to the same effect.

No schematics, but a pretty interesting tutorial on autopilot and attitude control (click on "roll, pitch, yaw" part-way down the page):

Put the phrase
"negative feedback servo system" in google
Wade through results, should be something similar.

If you want the exact circuit, contact the manufacture with the model number.

I'd start with Sperry Rand, just since they were the biggest manufacturer of autopilots when I was flying. Don't know about current stuff.
