COURSE DEVIATION INDICATOR (CDI)
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.

Navigation Source
The CDI can display two sources of navigation: GPS or NAV (VOR, localizer). Color indicates the current
navigation source: magenta (for GPS) or green (for VOR and LOC); the Selected Course readout also follows
these color indications. When coupled to GPS, the full scale limits for the CDI are defined by a GPS-derived
distance. When coupled to a VOR or localizer (LOC), the CDI has the same angular limits as a mechanical CDI.
If the CDI exceeds the maximum deviation on the scale (two dots) while coupled to GPS, the crosstrack error
(XTK) is displayed below the white aircraft symbol.
