It is always (in my experience) X positive aft, Y positive right, with the
origin being seemingly arbitrary.
seen that uses this coordinate system. The one I've seen the most is X positive forward,
Y positive right and Z positive down. Someone once told me this was named the
Boeing system. On the sim I'm working on now, it's positive Y forward, positive X
to the right and positive Z up. I'll admit that most of the sims I've worked on are
relatively old in FORTRAN and C.
Don't get me wrong, I'm not saying this is a bad system, I'm just not sure I agree it
is an industry standard...
