WARNING: Traffi c information shown on the GTN 725/750 is provided
as an aid in visually acquiring traffi c. Pilots must maneuver the aircraft
based only upon ATC guidance or positive visual acquisition of confl icting
traffi c.
WARNING: XM Weather should not be used for hazardous weather
penetration. Weather information provided by the datalink receiver 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.
WARNING: For safety reasons, GTN 725/750 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 725/750 Pilot's Guide as well as this
guide. Thoroughly practice basic operation prior to actual use. During
fl ight operations, carefully compare indications from the GTN 725/750
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 datalinked 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 identifi ed 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 GTN 725/750 utilize
GPS as a precision electronic NAVigation AID (NAVAID). Therefore, as with
all NAVAIDs, information presented by the GTN 725/750 can be misused
or misinterpreted and, therefore, become unsafe.
