CDI ‘DR’ Indication on PFD
As a result of operating in DR Mode, all GPS-derived data is computed based upon
an estimated position and is displayed as yellow text on the display to denote degraded
navigation source information. This data includes the following:
• Navigation Status Box fields except Active Leg, TAS, and DTK
• Course Deviation Indicator
• GPS Bearing Pointer
• Wind data and pointers in the Wind Data Box on the PFD
• Track Indicator
• All Bearing Pointer Distances
• Active Flight Plan distances, bearings, and ETE values
Also, while the system is in DR Mode, the autopilot will not couple to GPS, and
Terrain Proximity, TERRAIN-SVT, and TAWS are disabled. Additionally, the accuracy
of all nearest information (airports, airspaces, and waypoints) is questionable. Finally,
airspace alerts continue to function, but with degraded accuracy.
