DME INFORMATION WINDOW
The DME Information Window is displayed above the BRG1 Information Window on the 360˚ HSI and in
a box above and along side the Arc HSI. It 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 DME.
Displaying the DME Information Window:
1) Press the PFD Softkey.
2) Press the DME Softkey to display the DME Information Window.
3) To remove the DME Information Window, press the DME Softkey again.
4) Press the BACK Softkey to return to the top-level softkeys.
COURSE DEVIATION INDICATOR (CDI)
NOTE: During a heading change of greater than 105˚ with respect to the course, the CDI on the Arc HSI
switches to the opposite side of the deviation scale and displays reverse sensing.
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 CDI is not
displayed.

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 navigating GPS. When navigating using a VOR or localizer (LOC), the CDI uses the
same angular deviation as a mechanical CDI. 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.
