Eventide ARGUS 5000 - Page 28

On the right of the top line is the computed Track Error.
Your "track error" can be selected in the second AMEND page to be the difference
between your current track and either the desired track between your starting point
and your destination or the bearing from your present location to your destination.
The first is selected as DTK-TK, the second as BRG-TK. They are equivalent if you
are on your original course or flightplan; they differ if you drift or deliberately go off
course, as might occur if you want to fly parallel to a particular course.
Example: A leg of your flightplan is from MMU to SAX, a distance of 16.8NM on
a course of 354 degrees. The first screen below shows you essentially on-course.
Your course is 350 degrees, and the bearing to the destination is 354 degrees, so you
have a L4°TE, which means you should turn right 4 degrees to be on course. The
next screen shows you substantially off-course. If you select DTK-TK, as on this
screen, you have the same track error, even though the bearing to the waypoint is now
005°. Selecting BRG-TK on the third screen shows a track error of L15°TE, which
is the difference between your current track (350°) and the track that will get you to
your destination (005°.)

To summarize, select DTK-TK if you want to fly parallel to a particular course.
Select BRG-TK if you want the track error display to show you how much and in
what direction you need to turn to get to your destination waypointThe bottom line
of the lower window shows information generated by the Argus. On the right is the
