FLIGHT INSTRUMENTS
GPS steering guidance is still provided after the HSI automatically switches to LOC until LOC capture, up
to the Final Approach Fix (FAF) for an ILS approach, or until GPS information becomes invalid. Activating
a Vectors-to-Final (VTF) approach (see the GPS Navigation Section) also causes the HSI to switch to LOC
navigation source, although the change is not considered automatic to the system and GPS steering guidance
is not provided after this switch.
Changing the ILS CDI Capture setting:
1) Use the FMS Knob to select the AUX - System Setup Page on the MFD.
2) Press the FMS Knob to activate the cursor.
3) Turn the large FMS Knob to highlight the ‘ILS CDI Capture’ field in the ‘GPS CDI’ Box.
4) Turn the small FMS Knob to highlight the desired setting and press the ENT Key.
OBS M
ODE
NOTE: The OBS Softkey is available only when navigating an active leg using GPS.
Enabling Omni-bearing Selector (OBS) Mode (with the OBS Softkey) suspends the automatic sequencing
of waypoints in a GPS flight plan (GPS must be the selected navigation source), but retains the current
“active-to” waypoint as the navigation reference even after passing the waypoint. When OBS is disabled
(the OBS Softkey is pressed again), the GPS returns to normal operation, with automatic sequencing of
waypoints. OBS Mode also allows a desired course to/from a waypoint to be set (with the CRS Knob);
pressing the CRS Knob re-centers the CDI and returns the course pointer to the waypoint bearing.
As the aircraft crosses the missed approach point (MAP), automatic approach waypoint sequencing is
suspended. ‘SUSP’ appears on the HSI (to the lower right of the aircraft symbol) in place of ‘OBS’ and
the OBS Softkey label changes to SUSP. Pressing the SUSP Softkey resumes automatic of approach
waypoints.
Enabling/disabling OBS Mode while navigating with GPS:
1) Press the OBS Softkey to select OBS Mode.
2) Turn the CRS Knob to select the desired course to/from the waypoint.
3) Press the OBS Softkey again to return to normal operation.
