Functions
Bottom Row Keys
The CDI key is used to toggle which navigation source (GPS or VLOC) pro-
vides output to an external HSI or CDI.
The OBS key is used to select manual or 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 passing 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. When-
ever 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 is used to view system messages and to alert you to impor-
tant warnings and requirements. See Sections 10 and 9 for more information
on messages and unit settings.
The flight plan 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. See Section 4 for more
information on flight plans.
The procedures key allows you to select and remove approaches, departures
and arrivals from your flight plan. When using a flight plan, available pro-
cedures for your departure and/or arrival airport are offered automatically.
Otherwise, you may select the desired airport, then the desired procedure.
Whenever the GNS 430 is displaying a list
of information that is too long for the display
screen, a scroll bar will appear along the
right-hand side of the display. The scroll bar
graphically indicates the number of additional
items available within the selected category.
Simply press the small right knob (
a
) to
activate the cursor and rotate the large right
knob (
d ) to scroll through the list.
