Nice spray from an old codger, Landflap. Here's the thing, Landflap. My second "quote" was abbreviated, I admit (the overall message being the same), but my first reply (which you have not addressed, or cannot see the difference between a wobbly NPA caused by map shift and the help how modern technology I quoted helps the pilot) still stands:

Not to mention, in some countries, Distance/Altitude scales on the charts which remove all of the profile guesswork...
Let me be more clear: I never mentioned map shift, or "build you own" approaches (which, incidentally includes mucking about with the vertical profile as well as putting in your own LNAV path). You are talking about then; I'm talking about now. With
no FMS assistance, NPAs
are easier now because of the technology available. It does work, and works very well to reduce workload.
Re map shift, I very much doubt whether any authority would allow NPAs to be flown
today in non-GPS augmented aeroplanes without stringent monitoring of the raw data, if at all.
