WARNINGS, CAUTIONS, AND NOTES
The Garmin system, as installed in this aircraft, has a very high degree of functional integrity.
WARNING:
However, the pilot must recognize that providing monitoring and/or self-test capability for all conceivable
system failures is not practical.
The United States government operates the Global Positioning System and is solely responsible
WARNING:
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.
To reduce the risk of unsafe operation, carefully review and understand all aspects of the G950
WARNING:
Pilot's Guide documentation and the G950 Integrated Avionics System in the Airplane Flight Manual.
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.
Do not use the system to attempt to penetrate a thunderstorm. The illustrations in this guide are

only examples. Both the FAA Advisory Circular, Subject: Thunderstorms, and the Aeronautical Information
Manual (AIM) recommend avoiding any thunderstorm identified as severe of giving intense radar echo by
at least 20 miles.
