Warnings, Cautions & Notes
WARNING: Do not use the indicated data link weather product age to
determine the age of the weather information shown by the data link weather
product. Due to time delays inherent in gathering and processing weather
data for data link transmission, the weather information shown by the data
link weather product may be significantly older than the indicated weather
product age.
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: The illustrations in this guide are only examples. Never use the
G3X to attempt to penetrate a thunderstorm. Both the FAA Advisory Circu-
lar, 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: Because of variation in the earth's magnetic field, operating the
G3X 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 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 G3X utilize GPS as a precision
electronic NAVigation AID (NAVAID). Therefore, as with all NAVAIDs, informa-
tion presented by the G3X can be misused or misinterpreted and, therefore,
become unsafe.
