Warnings, Cautions & Notes
BATTERY WARNINGS:
If these guidelines are not followed, the lithium-ion battery may experience
a shortened life span or may present a risk of damage to the device, fire,
chemical burn, electrolyte leak, and/or injury.
• Do not leave the battery exposed to a heat source or in a high
temperature environment. To help prevent damage, store the battery
out of direct sunlight.
• For maximum battery longevity, store within a temperature range of
-4˚F to 68˚F (from -20˚C to 20˚C).
• Do not use a sharp object to remove the battery.
• Do not disassemble, puncture, damage, or incinerate the device or
battery.
• Keep the battery away from children.
• Only replace the battery with the approved replacement from Garmin.
Using another battery presents a risk of fire or explosion. To purchase
a replacement battery, see you Garmin dealer or the Garmin website.
• Contact your local waste disposal department to dispose of the device
and battery in accordance with applicable local laws and regulations.
WARNING: To reduce the risk of unsafe operation, carefully review and
understand all aspects of the Pilot's Guide. Thoroughly practice basic
operation prior to actual use. During flight operations, carefully compare
indications from the G5 to all available flight displays. For safety purposes,
always resolve any discrepancies.
WARNING: The altitude calculated by the G5 internal GPS receiver is
geometric height above Mean Sea Level and could vary significantly from the
altitude displayed by pressure altimeters. Always use the pressure altitude
display, when available, for determining or selecting aircraft altitude.
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.

Warnings, Cautions & Notes
WARNING: For safety reasons, the G5 operational procedures must be learned
on the ground.
WARNING: 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 Proposition
65. If you have any questions or would like additional information, please
refer to our website at www.garmin.com/prop65
CAUTION: The display uses a lens with a special coating that may be sensitive
to certain oils, waxes, and abrasive cleaners. CLEANERS CONTAINING
AMMONIA WILL HARMTHE ANTI-REFLECTIVE COATING. It is very important
to clean the lens using a clean, lint-free cloth and a cleaner that is specified
as safe for anti-reflective coatings. Avoid any chemical cleaners or solvents
that can damage plastic components.
CAUTION: The G5 does not contain any user-serviceable parts. Repairs should
only be made by an authorized Garmin service center. Unauthorized repairs
or modifications could result in permanent damage to the equipment and
void both the warranty and the authority to operate this device under FAA,
FCC, and other applicable regulations.
NOTE: The G5 may only be installed in type-certificated aircraft in accordance
with Garmin STC SA01818WI.
NOTE: The term LRU, as used throughout this manual is an abbreviation for
Line Replaceable Unit. LRU is used generically in aviation for a product (such
as a GSA 28 or GMC 507) that can be readily "swapped out" (usually as a
single component) for troubleshooting/repair.

G5 Electronic Flight Instrument Pilot's Guide for Certified Aircraft
190-01112-12 Rev. F
Warnings, Cautions & Notes
NOTE: The G5 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 G5. 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.
NOTE: All visual depictions contained within this document, including screen
images of the G5 display, are subject to change and may not reflect the most
current G5 functionality.
NOTE: Use of polarized eyewear may cause the display to appear dim or
blank.

System Overview
System Overview Flight Instruments AFCS Additional Features Index
SECTION 1 SYSTEM OVERVIEW
The G5 Electronic Flight Instrument is installed as an attitude display indicator
(ADI) and/or horizontal situation indicator (HSI). The G5 contains integrated attitude/
air data sensors that provide display of attitude and secondary display of air data
information. The G5 can also be interfaced to an external sensor to provide heading
information. The G5 features a bright, sunlight readable, 3.5-inch color display. In the
case of aircraft power loss, the G5 battery sustains the G5 flight display with up to 4
hours of power.

1.3 APPLYING SYSTEM POWER
During system initialization, the G5 displays the message ‘ALIGNING’ over the
attitude indicator. The G5 should display valid attitude typically within the first minute
of applying power. The G5 can align itself both while taxiing and during level flight.
1.4 OPERATION
1.4.1 G5 ANNUNCIATIONS
When a G5 function fails, a red 'X' is typically displayed over the instrument(s) or
data experiencing the failure. Upon applying power to the G5, certain instruments
remain invalid as equipment begins to initialize. All instruments should be operational
within one minute of applying power. If any instrument remains flagged, and it is
not likely an installation related problem, the G5 should be serviced by a Garmin-
authorized repair facility .

1.4.1.1 G5 ATTITUDE
The G5 calculates aircraft attitude using information from its built-in inertial sensors.
The G5 also uses GPS and airspeed data to provide the most accurate attitude
information. The G5 should display valid attitude within the first minute of applying
power.
If the G5 senses the attitude solution is valid, but not yet within the internal accuracy
limits, "ALIGNING" is displayed. The displayed attitude information is still accurate
and usable while this indication is shown. The G5 can align itself both while taxiing
and during level flight.
Figure 1-4 Attitude Aligning Indication
If the G5 senses the attitude solution is invalid, “ALIGNING KEEP WINGS LEVEL” is
displayed. No attitude information is displayed while this indication is shown. The G5
can align itself both while taxiing and during level flight.
Figure 1-5 Attitude Aligning Keep Wings Level Indication
If the G5 inertial sensors fail, “ATTITUDE FAIL” is displayed in addition to a red 'X'
over the display. No attitude information is displayed while this indication is shown.

1.4.1.2 G5 HEADING
The G5 can display magnetic heading information received from the GMU 11
magnetometer. If magnetic heading input data is not available, the G5 will display
GPS-derived ground track and the heading field will have a red 'X' displayed.
Figure 1-7 Heading Fail (PFD Page) Figure 1-8 Heading Fail (HSI Page)
If both magnetic heading and GPS are unavailable, the heading field will have a red
'X' displayed and the compass card will be removed from the HSI.
Figure 1-9 Heading/Track Fail (PFD Page) Figure 1-10 Heading/Track Fail (HSI Page)
The G5 corrects for shifts and variations in the Earth’s magnetic field by applying
the Magnetic Field Variation Database. The Magnetic Field Variation Database is
derived from the International Geomagnetic Reference Field (IGRF). The IGRF is a
mathematical model that describes the Earth’s main magnetic field and its annual
rate of change. The database is updated approximately every 5 years via a software
update. Failure to update this database could lead to erroneous heading information
being displayed to the pilot.
If the G5 senses the magnetic heading measurement is valid but possibly outside of
the internal accuracy limits, the numeric heading is displayed in yellow.
If the GAD 29B fails, VFR will be displayed in amber text and GPSS will be displayed
in amber text, if GPSS mode is selected.

1.5 ACCESSING FUNCTIONALITY
1.5.1 PAGES
NOTE: The G5 will automatically return to the PFD Page when the aircraft
enters an unusual attitude (if enabled in the system configuration). Refer to
the Installation Manual for more information.
The G5 has two main pages, the HSI Page and the PFD Page. The HSI Page can be
accessed from the PFD Page (unless it has been disabled in configuration).
