System Overview Flight Instruments EIS CNS Interface GPS Navigation Flight Instruments The Turn Rate Indicator is located above the Heading Strip. Tick marks to the left and right of the displayed heading denote standard turn rates (3 deg/sec). A magenta Turn Rate Trend Vector shows the current turn rate. The end of the trend vector gives the heading predicted in 6 seconds, based on the present turn rate. A standard-rate turn is shown on the indicator by the trend vector stopping at the standard turn rate tick mark, corresponding to a predicted heading of 18˚ from the current heading. At rates greater than 4 deg/sec, an arrowhead appears at the end of the magenta trend vector and the prediction is no longer valid. Turn Rate Trend Vector Turn Rate Indicator (Standard Rate Tick Marks) Heading Strip Current Heading Selected Heading Bug Current Track Indicator Heading Strip/Turn Rate Indicator OBS MODE NOTE: If configured, the selected external GPS navigator (i.e., GTN or GNS Series Units) is used to set the OBS Mode. Enabling Omni-bearing Selector (OBS) Mode suspends the automatic sequencing of waypoints in a GPS flight plan, but retains the current "active-to" waypoint as the navigation reference even after passing the waypoint. 'OBS' is annunciated to the left of the aircraft symbol when OBS Mode is selected. While OBS Mode is enabled, a course line is drawn through the "active-to" waypoint on the moving map. If desired, the course to/from the waypoint can now be adjusted. When OBS Mode is disabled, the GPS flight plan returns to normal operation with automatic sequencing of waypoints, following the course set in OBS Mode. The flight path on the moving map retains the modified course line. Flight Planning Hazard Avoidance Additional Features Integrated Autopilot Annun/Alerts Appendix Index 190-01115-00 Rev.
