WARNINGS,
CAUTIONS, AND NOTES
WARNING: Navigation and terrain separation must NOT be predicated upon the use of the TERRAIN function.
The TERRAIN feature is NOT intended to be used as a primary reference for terrain avoidance and does not
relieve the pilot from the responsibility of being aware of surroundings during flight. The TERRAIN feature is
only to be used as an aid for terrain avoidance and is not certified for use in applications requiring a certified
terrain awareness system. Terrain data is obtained from third party sources. Garmin is not able to independently
verify the accuracy of the terrain data.
WARNING: The terrain data should be used only as an aid for situational awareness. Terrain data must not
be used as the sole basis for decisions or maneuvers to avoid terrain or obstacles. Terrain data must not be
used for navigation.
WARNING: The altitude calculated by GPS 400 GPS receivers is geometric height above Mean Sea Level and
could vary significantly from the altitude displayed by pressure altimeters in aircraft. GPS altitude should never
be used for vertical navigation. Always use pressure altitude displayed by pressure altimeters in the aircraft.
WARNING: The Jeppesen database used in the GPS 400 system must be updated regularly in order to ensure
that its information remains current. Updates are released every 28 days. A database information packet is
included in the GPS 400 package. Pilots using an outdated database do so entirely at their own risk.
WARNING: The basemap (land and water data) must not be used for navigation, but rather only for nonnavigational situational awareness. Any basemap indication should be compared with other navigation
sources.
WARNING: For safety reasons, GPS 400 operational procedures must be learned on the ground.
WARNING: The United States government operates the Global Positioning System and is solely responsible for
its accuracy and maintenance. GPS is subject to changes which could affect the accuracy and performance of all
GPS equipment. Portions of the Garmin GPS 400 utilize GPS as a precision electronic NAVigation AID (NAVAID).
Therefore, as with all NAVAIDs, information presented by the GPS 400 can be misused or misinterpreted and,
therefore, become unsafe.

INTRODUCTION
1.3 TAKEOFF TOUR
reading within this Pilot’s Guide includes:
Overview
The Garmin GPS 400 provides the pilot accurate
navigational data, along with non-precision and precision
approach certification in the IFR environment. The takeoff
tour is designed to familiarize the pilot with:
• Powering up the unit
• Entering data
• Performing a simple direct-to
• Selecting IFR procedures
• Using some limited flight plans
In addition, this section briey covers the Default NAV
Page, the Map Page, and the NAV/COM Page, which are
available as part of the NAV Page Group. These pages are
used for most of the in-flight navigation.
The takeoff tour assumes that the unit and antennas
have been properly installed and that the GPS 400’s
default settings have not been changed. If any of the
factory default settings (position format, units of measure,
selectable elds, etc.) have been changed, the pictures
shown here may not exactly match what is shown on
the GPS 400. Prior to using the GPS 400 for the first
time, Garmin recommends that the aircraft be moved to a
location that is well away from buildings and other aircraft
so the unit can collect satellite data without interruption.
This takeoff tour is intended to provide a brief
introduction of the GPS 400’s major features. Sections
2 through 12 of this manual describe these features, and
others, in additional detail. Refer to these sections, as
needed, to learn or review the details regarding a particular
feature.
Service staff is available during normal business hours
(U.S. Central time zone) at the phone and fax numbers
listed on page ii. Garmin can also be reached by mail
(page ii) or at our website address, www.garmin.com.
Powering up the GPS 400
left corner of the unit. Turning it clockwise turns unit
power on. After turning the unit on, a welcome page
appears briefly while the unit performs a self test,
followed sequentially by the Unit Type Page (Figure
1-4) and the Software Versions Page. Then (depending
on conguration) the Weather Page, the Trafc Page, the
Aviation Data Page, the Land/Terrain/Obstacles Database
Page, and the Situational Awareness Page are sequentially
displayed.

SECTION 1
INTRODUCTION
Satellite Status Page
The Satellite Status Page (Figure 1-10) appears as the
GPS 400 attempts to collect satellite information.
An ‘Acquiring’ status is displayed on the Satellite Status
Page, and the signal strengths of any satellites received
appear as ‘bar graph’ readings. This is a good indication
that the unit is receiving signals and a position x is being
determined. Following the first-time use of the GPS 400,
the time required for a position x varies, usually from
one to two minutes.
Figure 1-10 Satellite Status Page
If the unit can only obtain enough satellites for 2D
navigation (no altitude), the unit uses the altitude provided
by the altitude encoder (if one is connected).
The ‘INTEG’ annunciator (bottom left corner of the
screen) indicates that satellite coverage is insufcient to
pass built-in integrity monitoring tests. In the example
above, not enough satellites are being received to determine
a position. The Satellite Status Page shows the ID numbers
for the satellites and the relative signal strength of each
satellite received (as a bar graph reading).
‘Searching Sky’ indicates that satellite almanac data is
not available or has expired (if the unit hasn’t been used
for six months or more). This means the unit is acquiring
satellite data to establish almanac and satellite orbit
information, which can take five to ten minutes. The data
is recollected from the first available satellite. The Satellite
Status Page displays a ‘Search Sky’ status, and the message
annunciator (MSG), above the MSG Key also flashes to
alert the pilot of a system message, ‘Searching the Sky’.
Viewing a system message:
Press the MSG Key (Figure 1-11).
The Message Page appears and displays the status or
warning information applicable to the receiver’s current
operating condition.

INTRODUCTION
Nearest (NRST) Airspace Page
The last page in the NRST Page Group, the Nearest
Airspace Page (Figure 1-27), provides information for
up to nine controlled or special-use airspaces near or in
the flight path. Airspace information appears on this
page based on the same criteria used for airspace alert
messages:
• If the projected course will take the aircraft inside
an airspace within the next ten minutes, the
message ‘Airspace ahead -- less than 10 minutes’
appears.
• If the aircraft is within 2 nm of an airspace and
the current course will take the aircraft inside, the
message ‘Airspace near and ahead’ appears.
• If the aircraft is within 2 nm of an airspace and
the current course will not take the aircraft inside,
the message ‘Near airspace less than 2nm’ appears.
• If the aircraft has entered an airspace, the message
‘Inside airspace’ appears.
Figure 1-27 Nearest Airspace Page
By default, airspace alert messages are turned off.
When turned on, the message (MSG) annunciator located

INTRODUCTION
Flight Plans (FPL)
The GPS 400 lets the pilot create up to 20 flight plans,
with up to 31 waypoints in each flight plan. Flight plans
are created, edited, and activated using the FPL Key. The
FPL Page Group includes two pages: the Active Flight Plan
Page and the Flight Plan Catalog Page (Figures 1-29 and
1-30). The Active Flight Plan Page provides information
and editing features for the flight plan currently in use
(referred to as ‘ight plan 00’). The Flight Plan Catalog
Page serves as the main page for creating new flight plans,
as well as editing or activating previously created flight
plans.
Figure 1-29 Active Flight Plan Page
Since using flight plans is arguably one of the more
complex features of the GPS 400, it will only be discussed
briefly here, with focus on creating a new flight plan and
activating it to use for navigation. After reading through
this brief introduction, answers to additional questions
about flight plans can be found in Section 4, Flight Plans.

Figure 2-3 Default NAV Page
The Default NAV Page displays a graphic course
deviation indicator (CDI) across the top of the page.
Unlike the angular limits used on a mechanical CDI
coupled to a VOR or ILS receiver, full scale limits for this
CDI are dened by a GPS-derived distance (0.3, 1.0, or
5.0 nm), as indicated at both ends of the CDI. By default,
the CDI scale automatically adjusts to the desired limits
based upon the current phase of flight: enroute, terminal
area, or approach. The pilot may also manually select the
desired scale setting as outlined in Section 8.4.
The graphic CDI shows the aircraft’s position at the
center of the indicator, relative to the desired course (the
moving course deviation needle). As with a traditional
mechanical CDI, when off course simply steer toward the
needle. The TO/FROM arrow in the center of the scale
indicates whether the aircraft is heading TO (up arrow)
the waypoint or FROM the waypoint (down arrow).
