Bottom Row Keys

The nearest (NRST) key (400W/420W
N
only) displays the nearest airports page.
Then, turning the small right knob steps
through the NRST pages.
The CDI key (430W only) is used to toggle
C
which navigation source (GPS or VLOC) pro-
vides output to an external HSI or CDI.
The OBS key is used to select manual or
O
automatic sequencing of waypoints. Pressing
the OBS key selects OBS mode, which will
retain the current "active to" waypoint as
your navigation reference even after pass-
ing the waypoint (i.e., prevents sequencing
to the next waypoint). Pressing the OBS
key again will return to normal operation,
with automatic sequencing of waypoints.
Whenever OBS mode is selected, you may set
the desired course to/from a waypoint using
the OBS Page, or an external OBS selector on
your HSI or CDI.
The message key (MSG) is used to view
M
system messages and important warnings and
requirements. See Sections 11 and 9 for more
information on messages and unit settings.
The flight plan key (FPL) allows you to
create, edit, activate and invert flight plans,
F
as well as access approaches, departures and

Whenever the 400W-series unit is dis-
playing a list of information that is too
long for the display screen, a scroll bar

of the display. The scroll bar graphically
indicates the number of additional items
available within the selected category.
Simply press the small right knob to
activate the cursor and turn the large
right knob to scroll through the list.
The procedures key (PROC) allows you to
P
select and remove approaches, departures
and arrivals from your flight plan. When
using a flight plan, available procedures for
your departure and/or arrival airport are
offered automatically. Otherwise, you may
select the desired airport, then the desired
procedure.
