Default NAV Page

The first NAV page is the default NAV page. This
page may be quickly selected from ANY page by using
the CLR key.
To select the NAV group and display the default NAV
page, press and hold the CLR key.
The default NAV page displays a graphic course
deviation indicator (CDI) across the top of the page.
Unlike the angular limits on a CDI coupled to a VOR
or ILS receiver, full scale limits for this CDI are defined
by a GPS-derived distance (2.0, 1.0 or 0.3 NM). By
default, the CDI scale automatically adjusts to the
desired limits based upon the current phase of flight:
en route, terminal area or approach.

NOTE: Approachng the FAF, the GNS 400W-seres
unt automatcally rescales n an angular fashon.
Ths allows the LPV approach to be flown dentcally
to a standard ILS. At 2.0 NM from the FAF, CDI scal-
ng s tghtened from 1.0 to the angular full scale
deflecton defined for the approach.
You may also manually select the desired scale set-
ting as outlined in the Aux Setup section.

The graphic CDI shows your position at the center
of the indicator, relative to the desired course (the
moving course deviation needle). As with a traditional
mechanical CDI, when you're off course simply steer
toward the needle. The TO/FROM arrow in the center
of the scale indicates whether you are heading to the
waypoint (an up arrow) or if you have passed the
waypoint (a down arrow).
The following symbols are used—on the default
NAV page directly below the CDI—to depict the

Data Fields
Directly below the CDI appears the active leg of
your flight plan, or the direct-to destination when
using the direct-to key. This will automatically
sequence to the next leg of your flight plan as you
reach each interim waypoint. If no flight plan or
direct-to destination has been selected, the destination
field will remain blank.
