2.2.1.2 COURSE DEVIATION INDICATOR (CDI)
The HSI contains a Course Deviation Indicator (CDI) with a Course Pointer. The
course pointer (GPS or VLOC) points in the direction of the selected course.
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 is capable of displaying multiple sources of navigation (GPS, VLOC, or both)
depending on the external navigator(s) configured (refer to the G5 Installation Manual
Section for more information). Color indicates the current navigation source: magenta
(for GPS) or green (for VOR and LOC). The full-scale limits for the CDI are defined by a
GPS-derived distance when coupled to GPS. When coupled to a VOR or localizer (LOC),
the CDI has the same angular limits as a mechanical CDI.
