I guess that is what I was trying to ask.  Do 2d systems have have only
2 inputs even though their graphs can look like a 3d?  Or is this what a
3d system is?  If this is true, has there ever been systems that allow
three variables to calculate the fuel needed?  i.e. a variable for each
axis, x,y, and z.
