Hello, I am an AHRS Guy...
...and I have questions. Maybe an answer or two also.
I ran across this forum during web searches for information. I am an AHRS specialist and I am the maintenance support for the AHRS systems produced by a certain German manufacturer.
My professional background includes duties as a Weapons System Tech on P-3C Orions during the late 70s. I have a lot of RF experience in a wide range of settings, from on-site service to manufacturing. I spent a number of years in the civilian world wishing to re-enter the aviation fields, and I've been an AHRS specialist for seven years now.
So, back to AHRS: if it is pulled from an Sikorsky S-76 or S-92, Bell 412, Pilatus PC-12, Learjet 45 or 31A, Cessna 540/560 XL, and a few other aircraft anywhere in the world except for Europe (and maybe a few other places), then it will come to me. If I cannot fix it it will be sent to the manufacturer in Germany.
I am here primarily to get information. I have basically NO information on how the AHRS is integrated to the various display systems and this can make serving customers very difficult. I worked AHRS for two years before anyone told me that the T-6 trainer has only one AHRS system.
That's just one example. I'd sure like to pick the brains of a lot of folks who are nameless and faceless to me. 
In the course of acquiring knowledge I am more than willing to share some of my own. I am a customer-oriented kind of guy and I don't mind helping another fellow out. If you're working with one of these systems and it's giving you fits, or if you just want to know something then give me a holler. I'm always glad to help.

Welcome.
Just one question.
What is AHRS?

Thanks for the welcome.
The link is good, but doesn't make things very clear. The Attitude Heading Reference System drives your HSI or EHSI and your ADI or EADI. It can also provide information to the autopilot system. On some aircraft, like the T-6A, it provides information to the Trim Assist Device (not 100% sure the D is for device, though).
The systems I work with are solid-state, fiber-optic gyros. Some of the more sophisticated ones can operate as Inertial Reference Systems.

Bravo Sir.

Welcome just a tech, most of us do not work with attitude platforms past the component replacement level. Just Wiki'd the fibre optic gyro, sounds interesting. It was not long ago that I had worked aircraft with a V/G, D/G setup, at the same time working craft with triple redundant RLG/accelerometer set ups.
I miss the days of the old INS that could be revived by a drop check to remove carbon build up and was acceptable to be 30NM off on an 8 hr flight.. Huh RNP?

I've only just found out how laser gyros work & now we're on to fibreoptic gyros?
