0x00000000007e96fe in HeadingIndicator::update (this=0xc322430, dt=0)
at src/Instrumentation/heading_indicator.cxx:90
90 double factor = 0.01 / (spin * spin * spin * spin * spin * spin);
Similar lines at mrg.cxx:157, heading_indicator_fg.cxx:112 and
heading_indicator_dg.cxx:111
Apparently this value is only used as dt / factor, so we can get rid
of both divisions.
Note, this still leaves one instance at mrg.cxx:157 unfixed, suggestions?
