Yeah, this isn't cheating, it's using the tools available to you. On
the main map screen, the 430 doesn't show your ground track (the TRK
field), but the fields on that screen are configurable (something like
"menu - change data fields"). I always swap out the ground speed field
(which I'm only occasionally interested in, and can get from another
screen) with the TRK field, which I'm pretty much always interested in.


It takes the workload out of determining a heading that gets you your
wind correction. This "is nice", because this typically changes as you
descend.
