PROCEDURES Procedure 4 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, do either of the following to intercept the arc: • Follow a specified radial inbound to intercept the IAF. • Follow ATC vectors, which allow interception of 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. See figure 3. 1. Select KFMN as the destination, via the Direct-to key or as the last waypoint in a flight plan. 2. Press the PROC key and select the VOR DMW 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 en route mode to terminal mode. The CDI range gradually transitions from 5.0 to 1.0 nm, full range deflection. 4. If the approach has not already been activated, be sure to do so when cleared for the approach. 5. As the plane approaches the IAF (HIDOX), the waypoint message 'NEXT DTK 206°' is displayed in the navigation status bar on the PFD. As the IAF approaches, the message is replaced by a turn advisory 'TURN TO 206°'. 6. Follow the arc, keeping the CDI needle centered. 7. The next point in the approach is an intermediate fix "WILDE". As the plane approaches "WILDE" the waypoint mes- sage 'NEXT DTK 072°' is displayed. As the waypoint approaches, 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 the plane approaches the FAF, the waypoint message 'NEXT DTK 072°' is displayed. Make any adjustments necessary for the final course segment (FAF to MAP). 10. As the plane crosses 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 the plane approaches the MAP, the waypoint message 'ARRIVING AT WAYPOINT' is displayed. 12. As the plane crosses the MAP, 'SUSP' is displayed in the HSI and directly above the SUSP softkey, indicating 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. 30 Garmin G1000 Pilot's Training Guide - Instructor's Reference 190-00368-04 Rev. A

Procedure 4
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, do either of the following to intercept the arc:
•
Follow a specified radial inbound to intercept the IAF.
•
Follow ATC vectors, which allow interception of 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. See figure 3.
1.
Select KFMN as the destination, via the
Direct-to
key or as the last waypoint in a flight plan.
2.
Press the
PROC
key and select the VOR DMW 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 en route mode to terminal mode.
The CDI range gradually transitions
from 5.0 to 1.0 nm, full range deflection.
4.
If the approach has not already been activated, be sure to do so when cleared for the approach.
5.
As the plane approaches the IAF (HIDOX), the waypoint message ‘NEXT DTK 206°’ is displayed in the navigation status
bar on the PFD.
As the IAF approaches, the message is replaced by a turn advisory ‘TURN TO 206°’.
6.
Follow the arc, keeping the CDI needle centered.
7.
The next point in the approach is an intermediate fix “WILDE”.
As the plane approaches “WILDE” the waypoint mes-
sage ‘NEXT DTK 072°’ is displayed.
As the waypoint approaches, 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 the plane approaches the FAF, the waypoint message ‘NEXT DTK 072°’ is displayed.
Make any adjustments neces-
sary for the final course segment (FAF to MAP).
10.
As the plane crosses 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 the plane approaches the MAP, the waypoint message ‘ARRIVING AT WAYPOINT’ is displayed.
12.
As the plane crosses the MAP, ‘SUSP’ is displayed in the HSI and directly above the
SUSP
softkey, indicating 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.
