GPS 400W

GNC 420W

GNS 430W

N

 

The 

nearest

 (

NRST)

 key (GPS 400W 

and GNC 420W only) displays the nearest 
airports page. Then, turning the 

small right

 

knob steps through the NRST pages. 

C

 

In the GNS 430W, the 

CDI 

key is used to 

toggle which navigation source (GPS or 
VLOC) provides output to an external HSI or 
CDI. 

O

 

The 

omni-bearing selector (OBS) 

key 

is used for two functions: to activate OBS 
selection and as a suspend key. 

 

As a Suspend (SUSP) key, it is used to 
select manual or automatic sequencing of 
waypoints. Pressing this key selects SUSP 
mode, which retains the current “active to” 
waypoint as your navigation reference even 
after passing the waypoint (i.e., prevents 
sequencing to the next waypoint). Press-
ing the 

OBS 

key again returns 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. 

M

 

The 

message (MSG) 

key is used to view 

system messages, important warnings, and 
requirements. 

F

  The 

flight plan (FPL) 

key allows you to 

create, edit, activate and invert flight plans, 
as well as access approaches, departures and 
arrivals. A closest-point-to-flight-plan feature 
is also available from the 

flight plan 

key. 

P

  The 

procedures (PROC) 

key allows you 

to select approaches, departures and arriv-
als from your active 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.
