Garmin G300 Pilot’s Guide

190-00921-00 Rev. D

Warnings, Cautions & Notes

WARNING: Navigation and terrain separation must NOT be predicated
upon the use of the terrain function. The G300 Terrain Proximity 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 Proximity 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 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 G300 GPS receivers is geometric
height above Mean Sea Level and could vary significantly from the
altitude displayed by pressure altimeters. Always use pressure altitude
displayed by the G300 PFD when determining or selecting aircraft
altitude.

WARNING: Do not use outdated database information. Databases used
in the G300 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 Pilots using any outdated database do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: XM Weather should not be used for hazardous weather
penetration. Weather information is approved only for weather
avoidance, not penetration.

WARNING: NEXRAD weather data is to be used for long-range planning
purposes only. Due to inherent delays in data transmission and the
relative age of the data, NEXRAD weather data should not be used for
short-range weather avoidance.

Garmin G300 Pilot’s Guide

190-00921-00 Rev. D

Warnings, Cautions & Notes

WARNING: The illustrations in this guide are only examples. Never
use the G300 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: To reduce the risk of unsafe operation, carefully review and
understand all aspects of the G300 Pilot’s Guide documentation and the
Pilot’s Operating Handbook of the aircraft. Thoroughly practice basic
operation prior to actual use. During flight operations, carefully compare
indications from the G300 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:

Because of variation in the earth’s magnetic field, operating
the G300 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: The Garmin G300 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 G300. 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, G300 operational procedures must be
learned on the ground.

Garmin G300 Pilot’s Guide

190-00921-00 Rev. D

Warnings, Cautions & 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 G300 utilize
GPS as a precision electronic NAVigation AID (NAVAID). Therefore, as
with all NAVAIDs, information presented by the G300 can be misused
or misinterpreted and, therefore, become unsafe.

WARNING: The data contained in the terrain and obstacle databases
comes from government agencies. Garmin accurately processes and
cross-validates the data, but cannot guarantee the accuracy and
completeness of the data.

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.

CAUTION: The display uses 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 anti­reflective coatings.

CAUTION: The Garmin G300 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 G300 panel and displays, are subject to change
and may not reflect the most current G300 system and aviation
databases. Depictions of equipment may differ slightly from the actual
equipment.

Warnings, Cautions & Notes

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 our web site at www.garmin.com/
prop65.

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: Temporary Flight Restriction (TFR) data is provided by the FAA
and may not be updated outside of normal business hours. Confirm
data currency through alternate sources and contact your local FSS for
interpretation of TFR data.

ADC: Processes data from the pitot-static system and outside air –
temperature (OAT) sensor.

Engine/Airframe Unit: Receives and processes signals from the –
engine and airframe sensors.

AHRS: Provides aircraft attitude and heading information to the –
PFD. The AHRS contains advanced sensors (including accelerom­eters and rate sensors) and interfaces with the Magnetometer to
obtain magnetic field information, with the ADC to obtain air data,
and with the GDU to obtain GPS information. AHRS operation is
discussed later in this section.

NOTE:

Refer to Appendix C for more information on SD Card use and

databases.

The G300 data card slot uses Secure Digital (SD) cards and is located on the
upper right side of the display bezel(s). The SD card can be used for software
updates, checklist files, flight data logging, exporting Track Logs/User Waypoints,
and Importing/Exporting Flight Plans.

Installing an SD Card:

1)

Insert the SD card in the SD card slot with the card contacts facing the
display (the card should be flush with the face of the bezel).

2)

To eject the card, gently press on the SD card to release the spring
latch.

1.5 SYSTEM POWER-UP

During system initialization, the AHRS displays the message ‘AHRS ALIGN, KEEP
WINGS LEVEL’ over the attitude indicator. 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.

System Initialization

Current database information is also displayed during power-up including 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 acknowledges this information.
