Unless I am missing something obvious, this sort of thing should not
happen if the pilot has a picture showing his position relative to the
rest of the place.


The picture doesn't always help.

I was once safety pilot for a CFI candidate flying an ILS with a moving map
system. Even though the picture clearly showed the holding pattern, he
nonetheless turned the wrong way to do his course reversal on the wrong side
of the FAC.

My point is this was a simple mistake made by an experienced pilot I trust.
If it can happen to him, it can happen to me - or baseball stars.

Bassball stars are hobby pilots.

This crew was supposed to be highly-trained, experienced professionals.
The gross errors they made were inexcusable.

For a pro who understands the complete system, DME on a LOC makes it
very easy to know where you are at any time. All the essential
information provided by a moving map is provided by a localizer with DME
fixes.
