The KLN 90B gps has a small moving map in its panel display. The NTSB
report alluded to the standard practice was for a track up orientation.
Given that the moving map screen is fairly short vertically, maybe half
its width, in the track up presentation it may not have been as obvious
that they had overflown their waypoints...

Of course, from an armchair quarterbacking perspective, almost all of my
inflight GPS experience has been behind King products, the KLN 89B, -90B
and KLX-135, and didn't seem to have a problem with the display or
depictions. The display was also not on the center console between the
pilots, facing up (as opposed to on the main panel).

I work with this technology all the time, from the current air carrier
stuff down to the Garmin line. I find I am very comfortable with the
maps the Garmin 500 series have. I find less comfort level with the
Garmin 400 series (I prefer my handheld 296's map to the 400 series).

I have flown a few times in a Cessna with a King 89 and 90. I find
those moving maps to be virtually useless, and bad human factors, at
least for an occasional user of those devices.
