AIM 5-4-5(i)(2) "Approaches without VDPs have not been assessed for terrain clearance below the MDA, and may not provide a clear vertical path to the runway at the normally expected descent angle."
AIM 5-4-5(g) "...procedure designers perform a visual area obstruction evaluation.....Restrictions to instrument operations are imposed if penetrations of the obstruction clearance surfaces exist. These restrictions vary based on the severity of the penetrations, and may include increasing required visibility, denying VDPs and prohibiting night operations to the runway."
FL420, you may very well be right about the reason a VDP is charted. The way I see it, the key words in the above paragraph are "may include", as in it is not an all inclusive list. If anyone has more info on this please share it.
