Valin,
I think if AHRS confusion were the case in this instance, the data Brent
is pulling out of the IDU would reflect it. The data stored is based on
info from the AHRS for bank and pitch, pitot and static for airspeed and
altitude, and gps. The screen and IDU data would obviously reflect what
the AHRS was telling them, so I don't think the AHRS was the problem.
The dats Brent presented seems fairly consistant with the data from the
radar reports from ATC, and the airspeeds and g loading seem to predict
the failure was eminent. AHRS sounds like it was right on.
There is also a possibility that the very large multi-axis accelerations
from the severe turbulence disturbed the solid state AHRS enough that
the
SFS was displaying a very corrupted flight attitude<<<
