Key and Knob Functions

NRST

 

The nearest key (NRST) (GPS 
500W) displays the Nearest Airports 
page. Then, turning the small right 
knob steps through the NRST pages. 

CDI

 

The CDI key (GNS 530W) is used to 
toggle the navigation source (GPS or 
VLOC) which provides output to an 
external HSI or CDI.

OBS

 

The OBS key is used to select 
manual or automatic sequencing of 
waypoints. Pressing this key selects 
OBS mode, which retains the current 
“active to” waypoint as your naviga-
tion reference even after passing the 
waypoint (i.e., prevents sequencing 
to the next waypoint). Pressing the 
OBS key again returns to normal 
operation, with automatic sequenc-
ing 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. 

MSG

 

The message key (MSG) is used to 
view system messages and to alert you 
to important warnings and require-

ments when the MSG annunciator is 
displayed. See Sections 12 and 9 for 
more information on messages and 
unit settings. 

FPL

 

The flight plan key (FPL) 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. See Section 4 for more informa-
tion on flight plans. 

VNAV

 

The vertical navigation key 
(VNAV) allows you to create a three-
dimensional profile which guides 
you to a final (target) altitude at a 
specified location. See Section 10. 

PROC

 

The procedures key (PROC) allows 
you to select approaches, departures 
and arrivals from your flight plan. 
When using a flight plan, available 
procedures for your departure and/or 
arrival airport are offered automati-
cally. Otherwise, you may select the 
desired airport, then the desired 
procedure.
