Flying The Dme Arc - Garmin G1000 Reference Manual

SECTION 5 – MFD

Flying the DME ARC

The GPS overlay for a DME arc approach uses ad-
ditional 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 on 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.
Select KFMN as your destination, via the Direct-
1.
to key or as the last waypoint in a flight plan.
2. Press the PROC key and select the VOR DME
RWY 7 approach. From the transitions window,
select "HIDOX" as the IAF. Choose 'LOAD?' or
'ACTIVATE?' as appropriate.
3. Within 30 nm of KFMN, the G1000 switches
from enroute mode to terminal mode. The CDI
scale gradually transitions from 5.0 to 1.0 nm,
full scale 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), a waypoint
message (NEXT DTK 206°) appears in the navi-
gation status bar on the PFD. As the distance
to the IAF approaches zero, the message 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" a
waypoint message (NEXT DTK 072°) appears.
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.
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 scale deflection.
9. As you approach the FAF, a waypoint message
(NEXT DTK 072°) appears. Make any adjust-
ments 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, a waypoint message
(ARRIVING AT WAYPOINT) appears.
12. As you cross the MAP, "SUSP" appears 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.
