THAT'S what the MARK is all about, except pilots say "VICTOR."
My understanding was it was a three-dimensional heading on Star Trek, i.e. a plane might fly a heading of 265 degrees at 30,000 feet, whereas the Enterprise (fictionally) flew 265 mark 145 - Both an X/Y axis
*and* a Z axis, as there was no notion of altitude...
