Gentlemen,
My vague recollection is that the original AsA chart layout did display "Distance to MAP", but this was LESS intuitive because most modern GPS/FMS displays only present "Distance to Next Waypoint" in the primary field of view. Dist to MAP (or any other selected W/P) may be presented in another area of the CDU, if required.
I fall into the same Cat. of Operation you mentioned above. I'd suggest that the Lockhart River accident, as sad as it was, resulted from more than just procedure design.
