I have already made the below notes on all of my flight computer, data
logger pages to hopefully make competition pilots aware of the position the
US contest rules committee has made prohibiting the use of AHRS and other
blind flying instruments and devices
please see my page
http://wingsandwheels.com/lx_nav_lx8...ano_flight.htm
and other pages as well

"Instruments or devices equipped with any form or AHRS system (Artificial
Horizon) or Instruments that could be used for "Cloud Flying" that cannot be
completely disabled or removed are not permitted in any
SSA sanctioned competition!"
More details are available on link above or may be found on Contest Rules
and Rules Committee Documents

XCSoar has an artificial horizon? I did not know that.

Yes:

The code has been there for many years, but is disabled, the comment
says why. (Not my opinion/decision, I would not put artificial limits
on technology used by XCSoar)

This code will be reinstated when Johnny (and the rest of the
OpenVario project) finishes his new vario design, which includes a
real AHRS. The OpenVario project started long before Butterfly
announced their vario, but since it's a spare time project of a few
soaring geeks, it takes a bit longer.

Is this also the source of the faux AH found in L8000?- Hide quoted text -

Paul:
As in my warning about Butterfly, you and other vendors should ensure
that the pilots buying the devices from you that are represented to
have A/H functionality, know that these devices are not permitted
under current and future SSA competition rules.
Notwithstanding the disagreement by a vocal few, this policy is not
going to change any time soon.
It would be a big service to your customers to ensure that they are
informed and an even bigger service if you make a point of ensuring
that your suppliers know that there is a clarification of policy in
effect and a methodology for compliance.
There is adequate time before the majority of the contest season to
get this accomplished.
If there is a question about whether a product falls into this
catagory, the RC will work hard to give you a determination.
I guess Richard, Rex?,and Tim and I don't know who else would also be
well to heed this suggestion.
I don't think you want to be getting the angry call from your customer
on contest practice day that you sold him an instrument he can't use.
Thanks for you cooperation and service to the contest community.
