WARNING: Traffic information shown on the GTN 725/750 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: SiriusXM Weather should not be used for hazardous weather
penetration. Weather information 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
flight 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 identified as severe or giving an intense
radar echo."
WARNING: Do not use the indicated data link weather product age to
determine the age of 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.
