Is this also the source of the faux AH found in L8000?


Not quite:

*http://git.xcsoar.org/cgit/mirror/LK...n/Source/Draw/....

The rendering code was rewritten to make it look more fancy (LK8000
uses only the calculated bank angle, but not the pitch angle). *The
formula has never been changed in LK8000, it's still the old XCSoar 5
formula, which means it's still pretty unreliable, lacking real AHRS
input:

*http://git.xcsoar.org/cgit/mirror/LK...n/Source/Calc/....

The XCSoar 6 formula has been improved to consider acceleration sensor
input (if available):

*http://git.xcsoar.org/cgit/master/xc...omputer/BasicC....

Not so much better, though. *I'd say neither one is usable.
