Maneuvers and navigation must not be based solely on the display of terrain or obstacles on the
moving map terrain displays.
2.14 Terrain Alerts
Terrain alerts must be inhibited when landing at an airport that is not in the airport database.
2.15 Traffic Display
The display of traffic is intended as an aid to visual acquisition and must not be used as the sole basis
for aircraft maneuvering.
2.16 Surface Operations
SafeTaxi or Chartview functions shall not be used as the sole basis for ground maneuvering. SafeTaxi
and Chartview functions do not comply with the requirements of AC 20-159 and are not qualified to be
used as an airport moving map display (AMMD). SafeTaxi and Chartview use is limited to airport
surface orientation to improve flight crew situational awareness during ground operations.
2.17 Glide Range Ring
In the event of engine failure or engine malfunction, the Glide Range Ring must not be used to
d
etermine gliding distance. Refer to the airplanes’ Pilot’s Operating Manual / Airplane Flight Manual
for engine failure emergency procedures and glide distance data.
2.18 Powerplant Gauge Markings
Aircraft that were previously equipped with a fuel flow gauge which measured metered fuel pressure
may have this gauge replaced by a gauge which measures fuel flow directly. When these gauges
are replaced in accordance with this STC, the fuel pressure and fuel flow markings on such gauges
are replaced by equivalent fuel flow markings.
Fuel flow values may be in error by as much as 15% if the K factor calibration is improperly set. Do
not depend solely on the fuel flow indication or the fuel totalizer to determine fuel used, fuel remaining,
or fuel reserves.
The fuel computer functions must not be used as the primary means of determining the quantity of
fuel in the tanks.
The Manifold Pressure gauge and the Propeller RPM gauge are the primary means for setting
engine
power. The % power display is for information purposes only.
2.19 Weight and Balance
Weight and balance data provided by the G3X Touch is for flight planning purposes only. Consult
the aircraft’s Pilot’s Operating Handbook for the official weight and balance data.
2.20 Data link Products (SiriusXM, FIS-B, and Connext)
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
