DME INFORMATION WINDOW
NOTE:
DME radio installation is optional.
The DME Information Window is displayed above the Bearing 1 Information Window and shows the DME
label, tuning mode (NAV1, NAV2, or HOLD), frequency, and distance. When a signal is invalid, the distance
is replaced by “– –.– NM”. Refer to the Audio Panel and CNS Section for information on tuning the radios.
Displaying the DME Information Window:
1)
Press the
PFD Opt
Softkey.
2)
Press the
DME
Softkey to display the DME Information Window to the left of the HSI.

COURSE DEVIATION INDICATOR (CDI)
The deviation bar (D-bar) within the Course Deviation Indicator (CDI) moves left or right from the course
pointer along a lateral deviation scale to display aircraft position relative to the course. If the course deviation
data is not valid, the D-bar is not displayed.

Scale
The CDI can display two sources of navigation, GPS or VOR/LOC. The color indicates the current navigation
source, magenta for GPS and green for VOR and LOC. The full scale limits for the CDI are defined by a GPS-
derived distance when coupled to GPS. If the CDI exceeds the maximum deviation on the scale (two dots)
while navigating with GPS, the crosstrack error (XTK) is displayed below the white aircraft symbol. When
navigating using a VOR or localizer (LOC), the CDI uses the same angular deviation as a mechanical CDI.
