Desired Track
Desired Track is used for GPS navigation to provide the intended track
to a waypoint. The ‘DTK’ is the normal indicator when flying a GPS
active leg. The ‘CRS’ indicator replaces the ‘DTK’ indicator when the
GPS is operating in CRS mode (sometimes referred to OBS mode).
Refer to the GPS manual for more information.
The Desired Track is replaced with amber dashes if the data is failed.
Selected Course Arrow
If the heading option is used and navigation is active, then the selected
course arrow is shown on the direction tape. Refer to Figures 3-10,
3-11, and 3-12.
An upward pointing selected course arrow is shown at the selected
course/desired track value. A downward pointing selected course
arrow is shown at 180° from the selected course/desired track value.
The color of the selected course arrow is the same as the navigation
information.
Note - When the GPS navigator is operating in ‘True North’ mode, the
ESI-500 displays the true DTK or CRS value followed by a ‘T’, and the
Selected Course arrow is removed from the Direction Tape.”
For Localizer backcourse navigation, the backcourse annunciator ‘B/C’
will replace the ‘CRS’ descriptor when the current aircraft direction is
more than 110° from the selected course when configured for Heading
or Track direction display (refer to Figure 3-11).
To provide normal sensing of the lateral deviations (i.e. a displayed left
deviation indicates fly left, and a displayed right deviation indicates fly
right) when flying a backcourse approach, the course setting should be
set to the reciprocal of the approach course. (E.g., if flying a localizer
backcourse approach to runway 9, if the inbound course to Runway 9
is 090°, then the selected course should be set to the reciprocal value
270°. The ESI-500 detects the aircraft direction (090°) is opposite from
the course setting (270°), and indicates the ‘B/C’ approach type.)
For GPS navigation, the selected course is replaced with amber
dashes if the data is failed.
