AHRS - mag. compass -> max. difference

[Iselbewohner]

Quick question:

What is the maximum difference in the heading given by the standby magnetic compass and the heading given by the AHRS of a G1000?

Thanks in advance

180 degrees :ok:

Indeed, the max. theoretical difference would be 180 degrees, thank you ;-)

But is there a max. permissible difference defined?

Less than 180 degrees. :ok:
