2.4 ABNORMAL OPERATIONS
ABNORMAL GPS CONDITIONS
The annunciations listed in Table 2-3 can appear on the HSI when abnormal GPS conditions occur; see the
figure for examples. Refer to the Flight Management Section for more information on Dead Reckoning Mode.
Annunciation Location Description
LOI
Lower left of
aircraft symbol
Loss of Integrity Monitoring–GPS integrity is insufficient for the current
phase of flight
INTEG OK
Lower left of
aircraft symbol
Integrity OK–GPS integrity has been restored to within normal limits
(annunciation displayed for 5 seconds)
DR
Upper right of
aircraft symbol
Dead Reckoning–System is using projected position rather than GPS position
to compute navigation data and sequence active flight plan waypoints
Table 2-3 Abnormal GPS Conditions Annunciated on HSI
Figure 2-41 Example HSI Annunciations
As a result of operating in DR Mode, all GPS-derived data is computed based upon an estimated position and
is displayed in amber 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 (removed after 20 minutes)
• 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 Perspective system is in DR Mode, the autopilot will not couple to GPS, and terrain alerting (if
installed) is disabled. Additionally, the accuracy of all nearest information (airports, airspaces, and waypoints)
is questionable. Finally, airspace alerts continue to function, but with degraded accuracy.
