How do I find the space fixed flight angle or the Space Fixed Heading Angle. which HUD would I use or would I use Attitude MFD in Target Relative Mod (Target Sun)? I found these numbers in Apollo The Definitive Source Book.  It's also in Apollo The Numbers

Space Fixed Flight Path Angle is defined as 'Flight-path angle measured positive upward from the body-centered local horizontal plane to the inertial velocity vector' -I guess that would be pitch of the surface MFD.
And Space Fixed Heading Angle is the 'Angle of the projection of the inertial velocity vector onto the body-centered local horizontal plane, measured positive eastward from north' -that might be the heading of the surface MFD.
That's how I would interpret it -I'm no physicist, though. Orbital mechanics bring my brain to overload nearly every time -'up is down and left is right, seen from that orbital plane' -help!
