This implies that your two ADAHRS are not agreeing with each other. What version did you have before the upgrade? And did you press COMPARE to see what both sets of instruments look like? Regardless, you should get in touch with our technical support staff at 425-402-0433 or support at dynonavionics dot com for some further assistance on this.

Not too sure the version before the update,
When i pressed the compare button the right panel has the slip indicator all the way to the right along with the g meter -6g ,
and the compass both are reading different


Cheers for the reply

So that's indicating that there's something very wrong with that ADAHRS. That was probably the case since before you updated your software, but only recent versions have detected discrepancies between multiple ADAHRS. From here, you should give our tech support team a call at 425-402-0433 or an email at support at dynonavionics dot com for further help.

What if this error is being reported in a single screen/single ADAHRS installation?

 

[dynonsupport]

It is not possible to get a cross-check error in a system with only a single AHRS. It is a message indicating that there are two AHRS units in the system and they disagree. The Flight Design planes have two AHRS units.

The number of screens doesn't matter.

If you are getting "Cross Check Attitude" in yellow on the screen then that's related to GPS assist and is a different message.

I thought the message said Cross Check Error in a single system which is why I thought it wrong but I will recheck the system before contacting Support. Thanks.
