SYSTEM OVERVIEW FLIGHT INSTRUMENTS EIS Flight Instruments 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 Flight Phase Scale Crosstrack Error CDI Figure 2-22 Course Deviation Indicator The CDI can display two sources of navigation, FMS or VOR/LOC. Color indicates the current navigation source, magenta for FMS and green for VOR and LOC. The full scale limits for the CDI are defined by a GPSderived distance when coupled to GPS. When navigating using a VOR or localizer (LOC), the CDI uses the same angular limits 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. & CNS AUDIO PANEL AVOIDANCE MANAGEMENT FLIGHT HAZARD AFCS ADDITIONAL FEATURES APPENDICES Figure 2-23 Navigation Sources 78 Garmin G2000 Pilot's Guide for the Cessna T240 190-01263-01 Rev.
