bruno my quick read on Paul's website indicates that that is exactly
how the Butterfly works, it triggers a line in the IGC file that says
the artificial horizon was used. Like you say I think that is a good
way to address this. If **** happens and you get sucked into a cloud
(See "Into the Bowels of Darkness" by Kempton Izuno) you have the
instrument available to save your life, but you trade your life for
zero points.
