Basic Operation
on the bottom left of the screen). “SUSP” indicates that automatic sequencing of approach
waypoints is
suspended on the current leg and normally appears at holding patterns or upon
reaching a Pilot Nav Leg.
• For roll steering autopilots: roll steering is terminated when approach mode is selected on the
autopilot and is available after passing the MAP.
• Auto-Suspend is active for Vectors To Final (VTF) until on the “TO” side of the FAF and the
aircraft ground track is within a 45° course of the published in bound course. At this point, it will
automatically extinguish.
Points to Remember for Localizer or VOR-based Approaches
• The default factory setting allows the CDI output to automatically switch from the GPS receiver
to the LOC receiver. If the “ILS Autoswitch” setting is changed to “Manual”, you must determine
when to select “GPS” or “VLOC” guidance during the approach. Remember, “LOC” is required for
the final course segment from Final Approach Fix (FAF) to MAP.
• If the CDI output has not automatically switched from GPS to ILS upon reaching the FAF, you
must manually switch to the VLOC receiver by pressing the CDI key. Verify that “LOC” or “VOR”
is displayed directly next to the CDI key.
• Automatic switching of CDI output is available for ILS, localizer, SDF and LDA approaches. Auto-
matic CDI switching is not available for backcourse approaches or VOR approaches.
• When flying an approach with the autopilot coupled, you must monitor system functions at all
times and verify that the autopilot and external CDI (or HSI) switch to the VLOC receiver with
sufficient time to capture and track the approach course. Switching to “VLOC” late in the ap-
proach may not provide the autopilot enough time to respond and intercept the approach course
prior to the FAF (depending upon the performance characteristics of your autopilot and aircraft).
In such instances, you should manually fly the approach or refer to the documentation provided
with your autopilot.

NOTE: While flying Direct-To the
FAF with VTF active, Vertical Guid-
ance will be disabled. To reestablish
Vertical Guidance, restart VTF by
pressing
PROC and VTF .
