Datalink Weather Display (Optional); Traffic Display (Optional); Stormscope ® Display (Optional) - Garmin GTN 625 Flight Manual

2.17 Datalink Weather Display (Optional)

This limitation applies to datalink weather products from SiriusXM via a GDL
69/69A, FIS-B via a GDL 88 or GTX 345, and Connext via a GSR 56.
Do not use data link weather information for maneuvering in, near, or around
areas of hazardous weather. Information provided by data link weather products
may not accurately depict current weather conditions.
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.
Do not rely solely upon data link services to provide Temporary Flight
Restriction (TFR) or Notice to Airmen (NOTAM) information. Not all TFRs
and NOTAMS can be depicted on the GTN.
Datalink text weather is decoded for the convenience of the pilot, however it is
possible that the decoding may be affected by anomalies in the data or
differences in the units of measure between the decoding system and the text
weather source. All text weather displayed on the GTN also includes the raw
weather text for pilot review.

2.18 Traffic Display (Optional)

Traffic may be displayed on the GTN when connected to an approved optional
TCAS I, TAS, TIS, or ADS-B traffic device. These systems are capable of
providing traffic monitoring and alerting to the flight crew. Traffic shown on the
display may or may not have traffic alerting available. The display of traffic is
an aid to visual acquisition and may not be utilized for aircraft maneuvering.
Traffic is displayed in feet regardless of the unit settings for altitude. If the units
for altitude are different than feet, a "FT" label will appear on the traffic icon on
and main map page, and the dedicated traffic page will include an "ALT IN FT"
notification.
2.19 StormScope
®
StormScope lightning information displayed by the GTN is limited to
supplemental use only. The use of the StormScope
display for hazardous weather (thunderstorm) penetration is prohibited.
®
StormScope lightning data on the display is intended only as an aid to enhance
situational awareness of hazardous weather, not penetration. It is the flight
crew's responsibility to avoid hazardous weather using official weather data
sources.
When the GTN StormScope
indicated by the "HDG N/A" label at the upper right corner of the StormScope
page, strikes must be cleared after each heading change.
