Approach with Hold
As you fly the holding pattern, a timer appears 
on the default NAV page. The timer automati-
cally resets on the outbound side of the hold 
when you are abeam the hold waypoint. The 
timer again resets as you turn inbound (within 
approximately 30° of the inbound course). This 
allows you to use standard timing (typically one 
minute) to fly the inbound and outbound legs 
of the hold. 
.   The 400W-series unit will provide course guid-
ance only on the inbound side of the holding 
pattern. When leaving the holding pattern 
to re-fly the approach (or another approach) 
press the PROC key to “Select Approach?” or 
“Activate Approach?” as previously described. 
(Or, use the direct-to key to select another 
destination.) 
Flying an Approach with a Hold
Starting where the previous example left off, 
we’ll assume weather conditions resulted in a missed 
approach at Lynchburg Regional. Now, you’ve decided 
to divert to Farmville Regional (KFVX) instead. 
1.   Press direct-to. 
2.   Use the small and large right knobs to enter 
the destination airport’s identifier (KFVX).

3.  Press ENT twice. 
This time, you select the GPS runway 21 approach 
into Farmville Regional. The GPS runway 21 approach 
begins with a holding pattern at the IAF, BODRY 
intersection. 
4.  Press PROC and select the “GPS 21” 
approach.

Approach with Hold
5.   From the transitions window, select BODRY 
intersection as the IAF.  Also, select “Activate?” 
to load and activate the approach. 
6.   Once you activate the approach, the active 
flight plan page will appear. You may review 
the approach sequence by pressing the small 
right knob and turning the large right knob. 
Press FPL to return to the navigation pages. 
7.   As in the last example, within 31 NM of the 
airport, the 400W-series unit will switch from 
en route mode to terminal mode, and the CDI 
scale will transition from 2.0 to 1.0 NM, full 
scale deflection. 
 NOTE: Upon activating an RNAV GPS approach, 
you are given the option to skip any non-required 
holding patterns during the initial transitions of 
the approach. In a GPS approach, you will not be 
given the option and you must manually reselect 
waypoint sequencing. 
8.   Just prior to crossing BODRY intersection, an 
alert—”HOLD  TEARDROP”—will appear in 
the lower right corner of the screen to sug-
gest the proper holding pattern entry. (“HOLD 
DIRECT” or “HOLD PARALLEL” may be offered 
on other similar approaches.) 
9.   As mentioned in the missed approach example, 
the default NAV page will display a timer or 
distance, as appropriate, during the holding 
pattern. Use this timer or distance to fly the 
outbound portion of the holding pattern. (The 
holding pattern is displayed on the map page 
and indicated as the active leg on the default 
NAV and active flight plan pages.)

 NOTE: If you need to lose extra altitude or speed 
by going around the holding pattern again, press 
OBS to manually suspend waypoint sequencing 
BEFORE crossing the holding waypoint the second 
time. If you’ve already passed this waypoint, re-
activate the holding pattern. 
11.  Also as you approach BODRY intersection, a 
waypoint alert (”NEXT  DTK 209°”) will appear 
in the lower right corner of the screen. 
12.  When within 45° of the final approach course 
and the FAF is the TO waypoint. CDI scaling is 
tightened from 1.0 NM full scale deflection to 
either 0.3 nautical mile or 2° full scale deflec-
tion whichever is less at the FAF. The change 
occurs over 2 NM and is completed by the 
FAF. 
13.   As you approach the FAF, a waypoint alert 
in the lower right corner (“NEXT  DTK 209°”) 
will appear. Make any course adjustments 
necessary for the final course segment (FAF 
to MAP). 
14.  As you cross the FAF, the destination sequences 
to the MAP (“RW21”, the runway threshold). 
With the needle centered, fly toward the MAP, 
observing the altitude minimums dictated by 
the approach plate. (When viewing the map 
page, you’ll note that the final course segment 
is displayed in magenta—the active leg of the 
flight plan always appears in magenta—and 
a dashed line extends the course beyond the 
MAP. Do NOT follow this extended course. 
Instead, follow published missed approach 
procedures.)

DME Arc Approach
15.  As you approach the MAP, a waypoint alert 
(“ARRIVING  WPT”) will appear in the lower right 
corner. CDI scaling continues to tighten from  
0.3 NM to 350 feet, full-scale deflection.
16.  As you cross the MAP, “SUSP” will appear 
above the OBS key, indicating that automatic 
sequencing of approach waypoints will be sus-
pended at the MAP. A “from” indication will 
be displayed on the CDI and default NAV page, 
but course guidance along the final approach 
course will continue. If a missed approach is 
required, use the OBS key to initiate the missed 
approach sequence. 
Flying a DME Arc Approach
The GPS overlay for a DME arc approach uses 
additional Jeppesen-provided waypoints to define the 
arc. These waypoints are indicated by “D” as the first 
letter in the waypoint name. This is followed by three 
numbers which indicate the radial the waypoint lies 
on. The last letter indicates the radius of the arc.

convention for an approach you select. 
This example is based upon a flight from Hutchin-
son (Kansas) Municipal (KHUT) to Billard Municipal 
(KTOP) in Topeka, Kansas. The VOR/DME runway 22 
approach will be selected, along with “D258G” as the 
IAF. 
1.   Select Billard Muni (KTOP) as your destination, 
via the Direct-To key or as the last waypoint

“LEBVY” as the IAF. Also, select “Load?” (or 
“Activate?”, if already cleared direct to the IAF 
for the approach). 
3.  Within 31 NM of KTOP, the 400W-series unit 
will switch from en route mode to terminal 
mode and the CDI scale will transition from 
2.0 to 1.0 NM, full scale deflection.

4.   If you haven’t already activated the approach 
(in step #2 above), be sure to do so when 
cleared for the approach. 
5.   As you approach the IAF (LEBVY/D258G), a 
waypoint alert (“LT TO 350° x S”, meaning 
turn left to 350° in x seconds) will appear in 
the lower right corner of the screen. As the 
distance (DIS) to the IAF approaches zero, the 
alert is replaced by a turn advisory (“LT TO 350°

6.   Follow the arc, keeping the CDI needle cen-
tered. When using an autopilot, the course 
select on the CDI (or HSI) must be periodically 
updated with the desired track (DTK) to ensure 
proper tracking through the arc. Whenever the 
course select setting and desired track differ 
by more than 10°, a “Set course to ###°” 
message will appear on the message page. 
7.   The next point in the approach is an interme-
diate fix, labeled “DMARY/D025G”. As you 
approach this intermediate fix, a waypoint alert 
(“RT TO 205° x S”) will appear in the lower 
right corner of the screen. As the distance to 
this fix approaches zero, the alert is replaced 
by a turn advisory (“RT TO 205° NOW”). Dial 
this course into the CDI (or HSI) using the OBS 
knob and initiate a standard rate turn to this 
course heading. 
8.   When within 45° of the final approach 
course and the FAF is the TO waypoint, the 
400W-series unit will switch from terminal 
mode to approach mode. CDI scaling is tight-
ened from 1.0 NM full scale deflection to either 
0.3 NM or 2° full scale deflection whichever is 
less at the FAF. The change occurs over 2 NM 
and is completed by the FAF. 
9.   As you approach the FAF, “RT TO 214° x S” will 
appear in the lower right corner of the screen. 
Select this course on the CDI (or HSI) using the 
OBS knob and turn to the final course segment 
(FAF to MAP) heading.

Vectors-To-Final Approach
10.  As you cross the FAF, the destination sequences 
to the MAP (“RW22”, the runway threshold). 
With the needle centered, fly toward the MAP, 
observing the altitude minimums dictated by 
the approach plate. When viewing the map 
page, you’ll note that the final course segment 
is displayed in magenta (the active leg of the 
flight plan always appears in magenta) and 
a dashed line extends the course beyond the 
MAP. 
11.   As you approach the MAP, a waypoint alert 
(“ARRIVING WPT”) will appear in the lower 
right corner. CDI scaling continues to tighten 
from 0.3 NM to 350 feet, full-scale deflec-
tion. 
12.   As you cross the MAP, “SUSP” will appear 
above the OBS key, indicating that automatic 
sequencing of approach waypoints will be 
suspended at the MAP. A “from” indication 
will be displayed on the CDI and default NAV 
page, but course guidance along the final 
approach course will continue. Do NOT follow 
this extended course. Follow published missed 
approach procedures using the OBS key to 
initiate the missed approach sequence. 
Vectors to Final
Let’s take a second look at the “VOR 22” approach 
into Billard Municipal.  Instead of following the DME 
arc, ATC tells you to expect vectors onto the final 
approach course. There are several ways to select “vec-
tors to final” with the 400W-series unit. The first two 
options below will normally require the least workload 
to accomplish: 
•  When the approach is first selected, choose “VEC-
TORS” from the transitions window. 
•   Load a full approach — including the IAF from 
the transitions window. When cleared, press 
PROC and select “Activate Vectors-To-Final?”. 
•  Load the full approach. Use the direct-to key (by 
pressing it twice) from the active flight plan page 
to select the desired leg of the approach. 
To select “VECTORS” from the transitions window: 
1.    Select Billard Municipal (KTOP) as your desti-
nation, using the direct-to key, or as the last 
waypoint in a flight plan. 
2.   Press the PROC key and select the “VOR 22” 
approach. 
3.   From the transitions window, select “VEC-
TORS”.

Vectors-To-Final Approach
4.   Select “Load?” (or “Activate?”, if already on 
vectors-to-final). 
To activate vectors-to-final from the procedures 
page: 
1.   Select Billard Municipal (KTOP) as your desti-
nation, using the direct-to key or as the last 
waypoint in a flight plan. 
2.   Press the PROC key and select the “VOR 22” 
approach. 
3.   From the transitions window, select “LEBVY” 
as the IAF. Also, select “Load?”. 
4.   When cleared, press the PROC key and select 
“Activate Vector-To-Final?”. 
Flying the Vectors Approach
With “vectors to final” selected, the CDI needle 
will remain off center until you’re established on the 
final approach course. With the approach activated, 
the map page will display an extension of the final 
approach course in magenta (remember, magenta is 
used to depict the active leg of the flight plan) and 
“VTF” will appear as part of the active leg on the 
default NAV page (as a reminder that the approach was 
activated with vectors-to-final). In this example, we’ll 
assume ATC vectors result in a rectangular course to 
intercept final, as follows:

2.  The unit suspends automatic waypoint 
sequencing in this case, because VTF was 
activated while on the “From” side of the Final 
Approach Fix. 
3.   ATC instructs you to turn left to a heading 
of 025°. This places you parallel to the final 
approach course in the opposite direction. CDI 
needle deflection is to the left. 
4.   ATC instructs you to turn right to a heading of 
115°. 
5.   ATC instructs you to turn right to a heading of 
175° to intercept the final approach course. As 
you converge with the final approach course 
the needle moves toward the center. (In the 
illustration below, the needle has returned 
to the on-screen CDI and your current posi-
tion is less than 0.5 NM right of the final 
approach course.) Once the aircraft is within 
the approach course and the CDI is active, 
automatic waypoint sequencing resumes and 
SUSP is removed. 
6.   As the CDI needle centers, make any remaining 
course corrections to establish yourself on the 
final approach course.

On-screen CDI scaling continues to tighten to 
350 feet, full-scale deflection. 
9.  As you approach the MAP, a waypoint alert 
(“ARRIVE WPT”) appears in the lower right 
corner. 
10.   As you cross the MAP, “SUSP” appears 
above the OBS key, indicating that automatic 
sequencing of approach waypoints is sus-

displayed on the CDI and Default NAV Page, 
but course guidance along the final approach 
course continues. Do NOT follow this extended 
course. Follow published missed approach 
procedures using the OBS key to initiate the 
missed approach sequence. 
Course From Fix Flight Plan Legs
Certain approach, departure, and arrival procedures 
in the Jeppesen database contain course from fix flight 
plan legs. The 400W-series is able to load these legs 
into the flight plan along with the rest of the procedure 
data, and to provide navigation along these legs. 
There are three different types of course from fix legs: 
TYPE 1: Course from fix to distance, or Course 
from fix to DME distance
Course from fix to distance legs will appear in the 
flight plan like normal waypoints, but the destination 
name will always begin with a “D”, followed by a dis-
tance in tenths of nautical miles from the waypoint fix. 
This example uses the VOR/DME RWY 25 approach 
into Palmdale, California (KPMD) and includes a 
teardrop course reversal.
