Warnings, Cautions & Notes
WARNING: Do not use data link weather information for maneuvering in,
near or around areas of hazardous weather. Information contained within data
link weather products may not accurately depict current weather conditions.
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: Do not rely on information from the lightning detection system
display as the sole basis for hazard weather avoidance. Range limitations
and interference may cause the system to display inaccurate or incomplete
information. Refer to the documentation from the lightning detection system
manufacturer for detailed information about the system.
WARNING: The Garmin system, as installed in this aircraft, 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.
WARNING: Do not use the system until carefully reviewing, and gaining
a thorough understanding of all aspects of the system's Pilot's Guide
documentation and the Airplane Flight Manual. Do not attempt to learn
system operational procedures while the aircraft is in the air. For safety
reasons, system operational procedures must be learned on the ground.
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 system utilize GPS as a
precision electronic NAVigation AID (NAVAID). Therefore, as with all NAVAIDs,
information presented by the system can be misused or misinterpreted and,
therefore, become unsafe.
