Flight Plans
The 400W-series lets you create up to 20 flight 
plans, with up to 100 waypoints in each flight plan. 
Flight plans are created, edited and activated using the 
FPL key. The FPL page group includes two pages: the 
active flight plan page and the flight plan catalog. The 
active flight plan page provides information and editing 
features for the flight plan currently in use (referred to 
as “flight plan 00”). The flight plan catalog serves as...

for the flight plan have been entered. Once the 
flight plan is created, it may be activated from 
an options window. Activating the flight plan

original flight plan still resides in the flight 
plan catalog). It replaces any flight plan which 
currently exists in “flight plan 00.”

Communicating Using the  
GNC 420W/AW and GNS 430W/AW
Some models of the 400W-series feature a digitally-
tuned VHF COM radio that provides a seamless transi-
tion from communication to navigation. The GNC 
420W and GNS 430W’s COM radio operates in the 
aviation voice band, from 118.000 to 136.975 MHz, 
in 25 kHz steps (default). For European operations, a 
COM radio configuration of 8.33 kHz steps is pro-
vided (Section 9 - Aux  - Setup 2). The GNC...

quency displayed in the GPS window can be trans-
ferred to the standby COM frequency field, with a 
minimum of keystrokes required. The following are 
some examples of selecting COM frequencies from 
some of the main GPS...
