I'm a track-up kind of guy too, it just seems to make more sense. I don't
particularly care where things are relative to some essentially arbitrary
coordinate system, I care where they are relative to me.

The big question is "which way do I have to turn when I reach the next
fix?" With head-up, it's right there in front of you. With north-up, you
have to mentally orient yourself first. Just one more place to screw up.

I think this is essentially a religious debate. For me, I am already oriented
by my charts, flight planning, plates, airport diagrams, etc. all of which are
north up. So to do something different on a GPS map display is confusing.
Hunting down the little north barb on the track up screen just doesn't do it.

I'll bet you don't turn your approach plates so they are track up! :-)

My CFII likes track-up, I prefer north-up. I'm going to suggest a
numbers page when we next fly together :-)

Having two computerized displays is one way to resolve this issue. My
EX500 MFD is set north-up for situational awareness and consistency
with mapping conventions. The 430 GPS is in generally in nav1 mode
with all the quantitative navigational numbers (CDI, track,
track-error). For a tactical traffic/weather scan, a brief visit to
graphical nav2 with track-up is enough.

No I don't, mosttly because it's inconvenient. On the other hand,
I've never been confused, even momentarially, about which way to turn
when looking at a track-up display.

Do whatever works best for you.

It has nothing to do with religion. It has to do with which display displays
more useful information. The "track up" display can be used like an HSI. The
"north" up cannot.

Keep the magenta line vertical (and start with the little airplane on the
line) and one is ON COURSE, "track up" only. This is a VERY EASY method of
staying on course.

And yes, I have turned my approach plates track up. I suspect the Bonanza I
followed into Missoula should have done that as well. He turned the wrong
way on the arc. Had he been looking at his chart "track up" it wouldn't have
happened.

They found the airplane three years later. I had to hold for 30 minutes
after he disappeared. The NW airliner, holding above us simply went on to
Great Falls.

Maybe I should have said "like religious zealotry." Reviewing the posts,
including yours, I rest my case. :-)

The ChartView feature of my MX20 will turn the displayed Jepp approach
plates track-up when the aircraft approaches a point that is within the
coverage of the chart.

In fair disclosure, though, I haven't retained the subscription of this
service, believing the cost outweighs the benefit of seeing the chart and
the aircraft's course overlaid therein.

With regard to paper charts, the more important information (in my opinion)
gleaned from these charts are the frequencies, initial, intermediate, and
final course headings, and minimum altitudes for each segment.

Turning the chart track-up makes it difficult to read this information,
although I will admit to momentarily turning the chart track-up as I
approach the IAF as a guide to situational awareness (more applicable to
VOR and GPS approaches, where course reversals or changes are more likely
to occur throughout the approach).

What 'track up" does is actually supply MORE useful information than "north"
up.

This is the case because the magenta line can and should be used as an HSI.
All one has to do is keep the magenta line vertical to stay EXACTLY on
course. This cannot be done with "north" up.

It is a very easy way to shoot approaches.
