"approach" mode. The CDI scale will decrease from 1 to 0.3 nautical miles.
14. Once you reach the FAF, a warning message will appear showing "NEXT DTK 209o" in the lower
right corner of the screen. Make any course adjustments necessary for the final course segment
(from the FAF to MAP).
15. After crossing the FAF, the destination point becomes MAP (runway 21, the runway edge). Hold
the needle in the center of the CDI, fly directly to the MAP, following the minimum permitted
altitude. (Looking at the map page, you will notice that the final rate is displayed in red - the
active section of the flight plan is always indicated by the color red - and a dashed line continues
the course behind the MAP. Do not follow the continuation of the course; instead, follow the
authorized procedures for missed approaches) .
16. After crossing the MAP, "SUSP" will be shown above the OBS indicating that the automatic
sequencing of approach waypoints is suspended at MAP. Note that "from" will be displayed on the
NAV and CDI pages, but course guidance along the final course will continue. If you want to
perform a missed approach, use the OBS button to start the missed approach.
DME Arc Approach.
The GPS overlay for DME arc approaches uses additional waypoints from the Jeppesen database to
determine the arc. These waypoints are displayed using the letter D at the beginning of the name of
the waypoint, followed by three digits indicating the radial where the waypoint is located. The last letter
indicates the radius of the arc.
For example:
D258G indicates a DME waypoint ("D") in a 258o radial at DME 7 (as "G" is the 7th letter of the
alphabet).
When you are ready for a DME arc approach, you must perform one of the following steps to cross the
arc:
• Follow the specific radial for intersection with the IAF.
• Follow the ATC vector, which will allow you to cross the arc at any point along the arc.
This example is based on a flight from Hutchinson Municipal Airport (KHUT) (Kansas) to Forbes Field
Airport (KFOE) in Toreka, Kansas. Approach 21 VOR / DME will be selected; the IAF will be waypoint
"D258G".
1. 1. Select Forbes Field (KFOE) as the destination by pressing DIRECT-TO or setting it as the
last waypoint in the flight plan.
2. 2. Press the PROC button and select the entry "VOR / DME 21". In the transitions window,
select "D258G" as the IAF. Also select "Load?" (Or "Activate?", If you are ready for approach.)
Within a 30-mile radius of KFOE, G430 switches from "enroute" mode to terminal mode, and
the CDI scale will go from 5 to 1 nautical mile.
3. 3. If you have not activated the approach (as described in step # 2), do it when you are
prepared for approach.
