REFERENCE
This example shows the
aircraft heading parallel to
the desired course, to the
right more than 0.5 nm.
This example shows the
aircraft even further off
course beyond the limits of
the CDI scale. The D-bar
will stay at the edge of the
scale until your cross-track
error is less than the limits
of the scale.

HSI PAGE
Whenever a GOTO, TracBack or route has been activated, the
GPSMAP 195 will provide digital and graphic guidance to the
destination waypoint with the HSI page. The top and bottom of the
page features eight user-selectable data fields that display
destination waypoint name (WPT), distance to waypoint (DIS), bear-
ing to waypoint (BRG), estimated time enroute (ETE), ground speed
(SPD) and more.
The center of the page is the HSI display. The HSI graphically
depicts the desired track to destination waypoint, ground track, cross
track error (course deviation) and a TO/FROM indication. The com-
pass card will rotate to indicate your current ground track at the top
of the page. The desired track pointer points in the direction of the
desired course to your destination waypoint and will rotate with the
compass card as your ground track changes.
The CDI (course deviation indicator) across the center of the
display shows your course deviation left or right of the desired
course. To get back on course and center the D-bar needle, steer
toward the D-bar needle. A TO/FROM indicator at the center of the
display indicates waypoint passage. The CDI scale setting is shown
on the status bar at the bottom of the page. The scale setting
represents the distance from the center of the CDI to full left or right
limits. The default CDI setting is 1.25 (nautical mile/statute
mile/kilometer), but can also be set for 0.25 or 5.0 ranges.
To change the CDI scale:
1. Press the
A
key in either direction (up to increase, down to
decrease the scale).
