Greetings,
In the Apollo By the numbers documents, they make several references to "Space Fixed Flight Path Angle(deg)", and "Space fixed Heading Angle(E of N)".
I understand that these are describing the craft's current attitude in space, but what is the reference point that is used.
I guess I am unsure what "space fixed" means.
Is there a way to use the HUD in ecliptic mode to get these same values?
