nings, Cautions, and Notes
WARNING:
Traffi c information shown on the GTN 625/635/650 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 GDL 69/69A 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 625/635/650 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 625/635/650 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 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 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 625/635/650
utilize GPS as a precision electronic NAVigation AID (NAVAID). Therefore,
as with all NAVAIDs, information presented by the GTN can be misused
or misinterpreted and, therefore, become unsafe.
