WARNINGS, CAUTIONS, AND NOTES
WARNING: Navigation and terrain separation must NOT be predicated upon the use of the terrain avoidance
feature. The terrain avoidance 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 avoidance feature is only to be used as an aid for terrain avoidance. Terrain data is obtained from
third party sources. Garmin is not able to independently verify the accuracy of the terrain data.
WARNING: The displayed minimum safe altitudes (MSAs) are only advisory in nature and should not be
relied upon as the sole source of obstacle and terrain avoidance information. Always refer to current
aeronautical charts for appropriate minimum clearance altitudes.
WARNING: The altitude calculated by G950 GPS receivers is geometric height above Mean Sea Level and
could vary significantly from the altitude displayed by pressure altimeters, such as the GDC 74A Air Data
Computer, or other altimeters in aircraft. GPS altitude should never be used for vertical navigation. Always
use pressure altitude displayed by the G950 PFD or other pressure altimeters in aircraft.
WARNING: Do not use outdated database information. Databases used in the G950 system must be updated
regularly in order to ensure that the information remains current. Pilots using any outdated database do so
entirely at their own risk.
WARNING: Do not use basemap (land and water data) information for primary navigation. Basemap data is
intended only to supplement other approved navigation data sources and should be considered as an aid to
enhance situational awareness.
WARNING: Traffic information shown on the G950 Multi Function Display is provided as an aid in visually
acquiring traffic. Pilots must maneuver the aircraft based only upon ATC guidance or positive visual
acquisition of conflicting traffic.
WARNING: The Garmin G950 has a very high degree of functional integrity. However, the pilot must
recognize that providing monitoring and/or self-test capability for all conceivable system failures is not
practical. Although unlikely, it may be possible for erroneous operation to occur without a fault indication
shown by the G950. It is thus the responsibility of the pilot to detect such an occurrence by means of cross-
checking with all redundant or correlated information available in the cockpit.
WARNING: For safety reasons, G950 operational procedures must be learned on the ground.

WARNINGS, CAUTIONS, AND NOTES
WARNING: The United States government operates the Global Positioning System and is solely responsible
for its accuracy and maintenance. The GPS system is subject to changes which could affect the accuracy
and performance of all GPS equipment. Portions of the Garmin G950 utilize GPS as a precision electronic
NAVigation AID (NAVAID). Therefore, as with all NAVAIDs, information presented by the G950 can be
misused or misinterpreted and, therefore, become unsafe.
WARNING: To reduce the risk of unsafe operation, carefully review and understand all aspects of the G950
Pilot’s Guide documentation and the Pilot’s Operating Handbook (POH) for the aircraft. Thoroughly practice
basic operation prior to actual use. During flight operations, carefully compare indications from the G950 to
all available navigation sources, including the information from other NAVAIDs, visual sightings, charts, etc.
For safety purposes, always resolve any discrepancies before continuing navigation.
WARNING : The illustrations in this guide are only examples. Never use the G950 to attempt to penetrate
a thunderstorm. Both the FAA Advisory Circular, Subject: Thunderstorms, and the Aeronautical Information
Manual (AIM) recommend avoiding “by at least 20 miles any thunderstorm identified as severe or giving an
intense radar echo.”
WARNING : Lamp(s) inside this product may contain mercury (HG) and must be recycled or disposed of
according to local, state, or federal laws. For more information, refer to our website at www.garmin.com/
aboutGarmin/environment/disposal.jsp.
WARNING : Because of variation in the earth’s magnetic field, operating the G950 within the following areas
could result in loss of reliable attitude and heading indications. North of 72° North latitude at all longitudes;
South of 70° South latitude at all longitudes; North of 65° North latitude between longitude 75° W and
120° W. (Northern Canada); North of 70° North latitude between longitude 70° W and 128° W. (Northern
Canada); North of 70° North latitude between longitude 85° E and 114° E. (Northern Russia); South of 55°
South latitude between longitude 120° E and 165° E. (Region south of Australia and New Zealand)
WARNING : Do not use GPS to navigate to any active waypoint identified as a ‘NON WGS84 WPT’ by a
system message. ‘NON WGS84 WPT’ waypoints are derived from an unknown map reference datum that
may be incompatible with the map reference datum used by GPS (known as WGS84) and may be positioned
in error as displayed.

190-01146-00 Rev. Aiv
WARNINGS, CAUTIONS, AND NOTES
CAUTION: The GDU 1040 PFD and GDU 1040 MFD displays use a lens coated with a special anti-reflective
coating that is very sensitive to skin oils, waxes, and abrasive cleaners. CLEANERS CONTAINING AMMONIA
WILL HARM THE ANTI-REFLECTIVE COATING. It is very important to clean the lens using a clean, lint-free
cloth and an eyeglass lens cleaner that is specified as safe for anti-reflective coatings.
CAUTION: The Garmin G950 does not contain any user-serviceable parts. Repairs should only be made by
an authorized Garmin service center. Unauthorized repairs or modifications could void both the warranty
and the pilot’s authority to operate this device under FAA/FCC regulations.
NOTE: All visual depictions contained within this document, including screen images of the G950 panel and
displays, are subject to change and may not reflect the most current G950 system. Depictions of equipment
may differ slightly from the actual equipment.
NOTE : This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
NOTE : Interference from GPS repeaters operating inside nearby hangars can cause an intermittent loss of
attitude and heading displays while the aircraft is on the ground. Moving the aircraft more than 100 yards
away from the source of the interference should alleviate the condition.
NOTE : Use of polarized eyewear may cause the flight displays to appear dim or blank.
NOTE : This product, its packaging, and its components contain chemicals known to the State of California
to cause cancer, birth defects, or reproductive harm. This notice is being provided in accordance with
California’s Proposition 65. If you have any questions or would like additional information, please refer to

busses. The PFD, MFD, and supporting sub-systems include both power-on and continuous built-in test features
that exercise the processor, RAM, ROM, external inputs, and outputs to provide safe operation.
During system initialization, test annunciations are displayed, as shown in Figure 1-4. All system annunciations
should disappear typically within the first minute of power-up. Upon power-up, key annunciator lights also
become momentarily illuminated on the Audio Panel, the MFD Control Unit, and the display bezels.
On the PFD, the AHRS begins to initialize and displays “AHRS ALIGN: Keep Wings Level”. The AHRS should
display valid attitude and heading fields typically within the first minute of power-up. The AHRS can align itself
both while taxiing and during level flight.
When the MFD powers up, the Power-up screen (Figure 1-5) displays the following information:
•Systemversion
•Copyright
•Landdatabasenameandversion
•SafeTaxidatabaseinformation(seeAdditionalFeatures)
•Terrain,AirportTerrain,Obstacle,andAviationdatabasename,version,andeffectivedates
Current database information includes valid operating dates, cycle number, and database type. When this
information has been reviewed for currency (to ensure that no databases have expired), the pilot is prompted to
continue.
Pressing the ENT Key (or right-most softkey) acknowledges this information, and the Navigation Map Page is
displayed upon pressing the key a second time. When the system has acquired a sufficient number of satellites to
determine a position, the aircraft’s current position is shown on the Navigation Map Page.

1.4 SYSTEM OPERATION
NOTE: The G950 system alerts the pilot when backup paths are utilized by the LRUs. Refer to the Appendices
for further information regarding system-specific alerts.
The displays are connected together via a single Ethernet bus for high-speed communication. As shown in
Figure 1-1, each IAU is connected to the on-side display. This section discusses normal and reversionary G950
display operation, AHRS modes, GPS receiver operation, and G950 System Annunciations.
DISPLAY OPERATION
NOTE: In normal operating mode, backlighting can only be adjusted from the PFD (see Section 1.7). In
reversionary mode, it can be adjusted from the remaining display(s).
In normal operating mode, the PFD presents graphical flight instrumentation (attitude, heading, airspeed,
altitude, vertical speed), replacing the traditional flight instrument cluster (see the Flight Instruments Section
for more information). The MFD normally displays a full-color moving map with navigation information (see
the Flight Management Section), while the left portion of the MFD is dedicated to the Engine Indication System
(see the EIS Section). Both displays offer control for COM and NAV frequency selection.
Figure 1-6 G950 System Normal Operation
In the event of a display failure, the G950 System automatically switches to reversionary (backup) mode. In
reversionary mode, all important flight information is presented on the remaining display(s) in the same format
as in normal operating mode.
• PFD failure – MFD enters reversionary mode.
• MFD failure – PFD enters reversionary mode.
If a display fails, the appropriate IAU-display Ethernet interface is cut off. Thus, the IAU can no longer
communicate with the remaining display (refer to Figure 1-1), and the NAV and COM functions provided to
the failed display by the IAU are flagged as invalid on the remaining display. The system reverts to backup
paths for the AHRS, ADC, Engine/Airframe Unit, and Transponder, as required. The change to backup paths is
completely automated for all LRUs and no pilot action is required.
