WARNING: Traffic information shown on the GTN 6XX is provided as an
aid in visually acquiring traffic. Pilots must maneuver the aircraft based only
upon ATC guidance or positive visual acquisition of conflicting traffic.
WARNING: Datalink weather should not be used for hazardous weather
penetration. Weather information provided by the GDL 69/69A is approved
only for weather avoidance, not penetration.
WARNING: Datalink 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, datalink weather data should not be used for short-range
weather avoidance.
WARNING: For safety reasons, GTN 6XX operational procedures must be
learned on the ground.
WARNING: To reduce the risk of unsafe operation, carefully review and
understand all aspects of the GTN 6XX Pilot’s Guide. Thoroughly practice
basic operation prior to actual use. During flight operations, carefully
compare indications from the GTN 6XX 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: Never use the datalink weather to attempt to penetrate a
thunderstorm. Both the FAA Advisory Circular, Subject: Thunderstorms, and
the Airman’s Information Manual (AIM) recommend avoiding “by at least
20 miles any thunderstorm identified as severe or giving an intense radar
echo.”
CAUTION: 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 GTN 6XX utilize
GPS as a precision electronic NAVigation AID (NAVAID). Therefore, as with
all NAVAIDs, information presented by the GTN 6XX can be misused or
misinterpreted and, therefore, become unsafe.
