Not clear (to me at least) is WHY they so clearly lost situational
awareness. Based on when they descended to MDA,and when and how they flew
the missed, they obviously thought they were someplace other than where they
were.
But why? Missing the fact that they autosequenced over the NDB might have
caused some confusion when flying the hold, but once inbound, both the GPS
(if they were using it) and the primary nav (presumedly tuned to the LOC
frequency) would both be showing dme to MAP. The gps would count down to
zero, the primary nav would go down to 1. How could either relying on a
potentially unreliable GPS OR missing the autosequencing have caused them to
to fly several miles PAST the MAP thinking that they had not yet reached it?
IIRC, they descended to MDA several miles PAST the MAP. They used the MAP as
the FAF, and seemed to fly a picture perfect approach thereafter. How could
misreading the GPS or NAV cause this??


I'd guess they weren't looking at the DME. The countdown to the FAF and the
countdown to the MAP don't look any different except for the waypoint name.

Why would they disregard the DME unless it wasn't working?
