PRIMARY FLIGHT DISPLAY
Course Deviation Indicator
The Course Deviation Indicator (CDI) moves to the left
or right of the course pointer along a deviation scale to
display aircraft position relative to the course.
The CDI has the same angular limits as a mechanical
CDI when coupled to a VOR or LOC. When coupled
to GPS, the full-scale limits for the CDI are defined by a
GPS-derived distance (5.0, 1.0, or 0.3 nm). The CDI scale
automatically adjusts to the desired limits based on the
current phase of flight (en route: 5.0 nm, terminal area:
1.0 nm, or approach: 0.3 nm). The desired GPS scale
settings may be selected manually on the MFD (refer to
the Multi Function Display section).

Bearing Pointers and Information Windows
Up to two bearing pointers can be displayed on the
HSI. Pressing the PFD softkey provides access to the
BRG1 and BRG2 softkeys. The BRG1 pointer is a single
cyan line with an open arrowhead at the end. The BRG2
pointer is a double cyan line with an open arrowhead at
the end. The bearing pointers never override the CDI.
When at least one bearing pointer is displayed (but not
necessarily visible if there is no data available), a white
ring appears around the center of the compass rose to
visually separate the bearing pointer(s) from the CDI.
When a bearing pointer is displayed, its associated
information window is also displayed.
