Flying the DME ARC
The GPS overlay for a DME arc approach uses
additional Jeppesen provided waypoints to define the arc.
When cleared for a DME arc approach, you may do either
of the following to intercept the arc:
• Follow a specified radial inbound to intercept the
IAF.
• Follow ATC vectors, which allow you to intercept
the arc at any point along the arc.
This example is based upon a flight from KSAF (Santa
Fe, NM Municipal) to KFMN (Farmington, NM Four
Corners Regional). The VOR DME RWY 7 approach is
selected along with "HIDOX" as the IAF.
1. Select KFMN as your destination, via the Direct-
to key or as the last waypoint in a flight plan.
Press the PROC key and select the VOR DMW
2.
RWY 7 approach. From the transitions window,
select "HIDOX" as the IAF. Choose 'LOAD?' or
'ACTIVATE?'
3. Within 30 nm of KFMN, the G1000 switches
from enroute mode to terminal mode. The CDI
range gradually transitions from 5.0 to 1.0 nm,
full range deflection.
4. If you haven't already activated the approach,
be sure to do so when cleared for the
approach.
5. As you approach the IAF (HIDOX), the waypoint
message 'NEXT DTK 206°' is displayed in
the navigation status bar on the PFD. As the
distance to the IAF approaches zero, the mes-
sage is replaced by a turn advisory 'TURN TO
206°'.

6. Follow the arc, keeping the CDI needle cen-
tered.
7. The next point in the approach is an intermedi-
ate fix "WILDE". As you approach "WILDE"
the waypoint message 'NEXT DTK 072°' is dis-
played. As the distance to this fix approaches
zero the message is replaced by a turn advisory
'TURN TO 072°'. Initiate a standard rate turn
to this course heading.
8. At 2.0 nm from the FAF (PINTO), the G1000
switches from terminal mode to approach
mode. CDI scaling is tightened from 1.0 to
0.3 nm, full range deflection.
9. As you approach the FAF, the waypoint mes-
sage 'NEXT DTK 072°' is displayed. Make
any adjustments necessary for the final course
segment (FAF to MAP).
10. As you cross the FAF, the destination sequences
to the MAP (RW07map, the runway threshold).
Keeping the CDI needle centered, fly toward
the MAP, observing the altitude minimums
dictated by the approach plate.
11. As you approach the MAP, the waypoint mes-
sage 'ARRIVING AT WAYPOINT' is displayed.
12. As you cross the MAP,'SUSP' is displayed in the
HSI and directly above the SUSP softkey, indi-
cating that automatic sequencing of approach
waypoints is suspended. A 'FROM' indication
is displayed on the CDI, but course guidance
along the final approach course continues. If
a missed approach is required, use the SUSP
softkey to initiate the missed approach.
