KEYS AND KNOBS
The CLR Key is used to erase information, remove
map detail, or to cancel an entry. Press and hold the CLR
key to immediately display the Default NAV Page.
The ENT Key is used to approve an operation or
complete data entry. It is also used to confirm information,
such as during power on.
The large right knob is used to select between the
various page groups: NAV, WPT, AUX, or NRST. With
the on-screen cursor enabled, the large right knob allows
the pilot to move the cursor about the page. The large

(turn clockwise) or left (counterclockwise) when the map
panning function is active.
The small right knob is used to select between the
various pages within one of the groups listed above. Press
this knob momentarily to display the on-screen cursor.
The cursor allows the pilot to enter data and/or make a
selection from a list of options. When entering data, the
small knob is used to select the desired letter or number
and the large knob is used to move to the next character
space. The small right knob is also used to move the target
pointer up (turn clockwise) or down (counterclockwise)
when the map panning function is active.

Bottom Row Keys
The NRST Key displays the Nearest Airports Page. Then,
turning the small right knob steps through the NRST pages.
The OBS Key is used to select manual or automatic
sequencing of waypoints. 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.
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
available from the FPL Key.
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.

to the final course segment of the approach
and will provide navigation guidance relative
to the final approach course.
GPS 400 Quick Reference
190-00140-61 Rev. E
ACTIVATE AN APPROACH
Not all approaches in the database are approved for GPS
use. As the pilot selects an approach, a ‘GPS’ designation
to the right of the procedure name indicates the procedure
can be flown using the GPS receiver. Some procedures
do not have this designation, meaning the GPS receiver
may be used for supplemental navigation guidance only.
ILS approaches, for example, must be flown by tuning the
VLOC receiver to the proper frequency and coupling the
VLOC receiver to the external CDI (or HSI).
A selected approach may be activated or loaded. Once
an approach is selected, it may be activated for navigation
from the Procedures Page. Activating the approach
overrides the ‘enroute’ portion of the active flight plan,
proceeding directly to the ‘approach’ portion (for a full
approach, directly to the initial approach fix). Activating
the approach also initiates automatic CDI scaling transition
as the approach progresses.
In many cases, it may be easiest to ‘Load’ the full
approach while still some distance away, enroute to the
destination airport. Later, if vectored to final, use the
following steps to select ‘Activate Vector-To-Final’—which
makes the inbound course to the final approach fix (FAF)
waypoint active. Otherwise, activate the full approach
using the ’Activate Approach?’ option.
190-00140-61 Rev. E
Activating an approach:
1)
With an approach loaded in the active flight
plan, press the PROC Key to display the
Procedures Page.
2)
Turn the large right knob to highlight ‘Activate
Approach?’ and press the ENT Key.
The ‘Activate Vector-To-Final?’ option allows the pilot
to activate the final course segment of the approach. This
option assumes the pilot will receive vectors to the FAF
and provides guidance to intercept the final course, before
reaching the FAF.
Activating the approach with vectors to
final:
1)
With an approach loaded in the active flight
plan, press the PROC Key to display the
Procedures Page.
2)
Turn the large right knob to highlight ‘Activate

FLYING AN APPROACH
Guidelines for Flying an Approach
Due to the variety of available approach procedures,
the specific steps required will vary according to the
approach selected. Keep in mind the following while
flying the approach:
• Selecting the destination airport as the last
waypoint in the active flight plan, or using the
Direct-to Key ensures that the desired waypoint
will automatically appear when choosing the
‘Select Approach?’ option from the Procedures
Page. Otherwise, the airport should be selected
first, then the approach procedure.
• As the aircraft progresses to each approach
waypoint, a waypoint alert message (‘NEXT DTK
# # #º’) will appear in the lower right corner of
the display (see page 14).
• Turn advisories (‘TURN TO # # #º’) will appear in
the lower right corner of the display (see page 14)
when the pilot should begin a course change (via
a standard rate turn).
• For GPS-based approaches, receiver autonomous
integrity monitoring (RAIM) monitors satellite
conditions and alerts the pilot using an ‘INTEG’
or ‘WARN’ annunciation at the bottom left corner
of the display (see page 14) if protection limits
cannot be maintained. If this occurs, the GPS
receiver should not be used for primary navigation
guidance. Revert to an alternate navigation
source, or select an alternate destination airport.
20
• Within 30 nm of the destination airport, CDI
scaling will transition from 5.0 nm (enroute
mode, ‘ENR’) to 1.0 nm (terminal mode, ‘TERM’)
or when leaving the departure airport, from 1.0 to
5.0 nm. Within 2.0 nm of the final approach fix,
GPS-based approaches will see a second transition
from 1.0 to 0.3 nm (approach mode, ‘APR’).
• A ‘START PROC TRN’ prompt will appear in
the lower right corner of the display to advise
the pilot when the aircraft is at a safe distance to
initiate a procedure turn. The procedure turn is
displayed on the Map Page, but guidance through
the turn itself is not provided.
• Alerts for proper holding pattern entry (e.g.,
‘HOLD DIRECT’) are displayed in the lower right
corner of the display. Waypoint sequencing is
automatically suspended (indicated by ‘SUSP
directly above the OBS Key) at the holding
waypoint. Press the OBS Key again to return
to automatic waypoint sequencing. For course
reversals, waypoint sequencing is suspended
for one trip around the holding pattern only
(after which it will return to automatic waypoint
sequencing).

• The CDI will guide the pilot through a DME arc.
Just keep the needle centered to fly along the arc.
When using an autopilot, the course select on the
CDI (or HSI) must be periodically updated with
the desired track (DTK).
• When crossing the missed approach point, ‘SUSP’
will appear above the OBS Key, indicating that
automatic sequencing of waypoint is suspended at
the missed approach point, and a ‘from’ indication
will appear on the CDI (or HSI).

Flying a Missed Approach:
1)
Press the OBS Key. The next waypoint in
the approach (MAHP, in this case ‘SWARM’
intersection) is automatically offered as the
destination waypoint.
2)
Follow the missed approach procedures, as
published on the approach plate, for proper
climb and heading instructions.
3)
An alert message in the lower right-hand corner
of the screen recommends entry procedures for
the holding pattern (e.g., ‘HOLD TEARDROP’).
When flying the holding pattern, a timer
appears on the Default NAV Page. The timer
automatically resets on the outbound side of
the hold when the aircraft turns abeam the
hold waypoint. The timer again resets as the
pilot turns inbound (within approximately 30°
of the inbound course). This allows use of
standard timing (typically one minute) to fly
the inbound and outbound legs of the hold.
4)
The GPS 400 provides course guidance only
on the inbound side of the holding pattern.
When leaving the holding pattern to re-fly
the approach (or another approach) press the
PROC Key to ‘Select Approach?’ or ‘Activate
Approach?’ as previously described. Or, use the
Direct-to Key to select another destination.
