 Troubleshooting Q&A
This section is designed to answer some of the 
common questions regarding the 400W-series capabili-
ties and operation. If you have a problem operating 
the unit, read through this appendix and refer to the 
reference section noted. If you don’t find answers to 
your particular question here, use the index to find the 
appropriate section elsewhere in this manual. If, after 
reading through the appropriate reference section, you 
still haven’t found the answer to...

What happens when I select an approach? Can I store a 
flight plan with an approach, departure or arrival? 
Whenever you load an approach, departure or arrival 
into the active flight plan, a set of approach, departure or 
arrival waypoints is inserted into the flight plan—along 
with a header line describing the instrument procedure 
you selected. The original en route portion of the flight 
plan will remain active, unless you “Activate” the instru-
ment procedure; which may be done when the...

flag for the active-to waypoint. If an external course in-
put is not available, you may select the OBS course on-
screen, via a “Select OBS Course” pop-up window. With 
OBS mode cancelled, the CDI will always display a “TO” 
indication for the next waypoint once you’ve crossed the 
active waypoint (provided the active waypoint is not the 
last waypoint). Refer to Section 5 - Flying the Missed Ap-
proach for an example using the OBS key. 
One application for the OBS key is holding patterns. 
The OBS...

How do I skip a waypoint in an approach, departure, 
or arrival?
The 400W-series unit allows you to manually select 
any approach, departure or arrival leg as the active leg of 
your flight plan. This procedure is performed from the 
active flight plan page by highlighting the desired waypoint 
and pressing direct-to twice, then ENT to approve the se-
lection (see illustration right). The GPS will then provide 
navigation along the selected flight plan leg, so be sure 
you have clearance to that...
