GPS Question
Um, OK, I'm thick. I don't get what substitution rule I'm still
missing? With either approach you're using the VOR head for lateral guidance and reading the distance from some fix in the GPS database from the GPS head. Even the example approach used for how to do a DME ARC in the KLN 94 GPS manual is an VOR/DME approach using an arc. I guess the idea is that your position "on track" and "along track" need differing amounts of, for lack of a better word, attention. You are pointed along track and will cover all the along-track positions. You want to remain on track, and not left or right of track. For a regular VOR approach, it is the VOR that keeps you on track. DME just reports your "along track" progress. For a DME arc it's the reverse. You stay "on track" referring to the DME, and the VOR just reports your "along track" progress.
