The terrain display is intended to serve as a situational awareness tool only. By
itself, it may not provide either the accuracy or the fidelity on which to base
decisions and plan maneuvers to avoid terrain or obstacles.
2.9 VNAV Vertical Navigation Calculation Page
VNAV information accessible by pressing the “VNAV” button may be utilized
for advisory information only. Use of VNAV information for Instrument
Approach Procedures does not guarantee Step-Down Fix altitude protection, or
arrival at approach minimums in a normal position to land.
2.10 Weather Display (Optional)
This limitation applies to data linked weather products from SiriusXM via a
GDL 69/69A or FIS-B via a GDL 88.
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 GNS.
2.11 Traffic Display (Optional)
Traffic may be displayed on the GNS 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.
2.12 Manual GTN Crossfill
When Manual GTN Crossfill is in use, the crew must verify each flight plan leg
prior to using the GNS to navigate. See section 7.2 for additional information.
2.13 Flight Stream 210 (Optional)
The Flight Stream 210 provides the ability for the crew to import flight plans
from a portable electronic device to the GNS. The crew must verify all flight
plan and waypoint information imported from a portable electronic device prior
to use on the GNS. See section 7.3 for additional information.
