INTRODUCTION
NOTE: When the GPS 400 displays a list of
information that is too long for the display
screen, a scroll bar appears along the right-hand
side of the display (Figure 1-3). The scroll bar
graphically indicates the number of additional
items available within the selected category. To
scroll through the list, press the small
right
knob
to activate the cursor, then turn the large

The
NRST
Key displays the Nearest Airports Page.
Then, turning the small
right
knob steps through the
NRST pages.
Pressing the
OBS
Key selects OBS mode, which
retains the current ‘active to’ waypoint as the navigation
reference even after passing the waypoint (i.e., prevents
sequencing to the next waypoint). Pressing the
OBS
Key again returns the unit to normal operation, with
automatic sequencing of waypoints. When OBS
mode is selected, the pilot may set the desired course
to/from a waypoint using the ‘Select OBS Course’ pop-up
window, or an external OBS selector on the HSI or CDI.
The
MSG
Key is used to view system messages and to
alert the pilot to important warnings and requirements.
See Section 12.1 for more information on messages.
The
FPL
Key allows the pilot 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 made available by pressing the
FPL
Key.
See Section 4 for more information on flight plans.
The
PROC
Key allows the pilot to select and remove
approaches, departures, and arrivals from the flight plan.
When using a flight plan, available procedures for the
departure and/or arrival airport are offered automatically.
Otherwise, the pilot may select the desired airport, then
the desired procedure.
