Engine Indication System

The G3X Touch EIS (if installed) displays engine, electrical, and other system parameters. Gauges
required to be displayed full time are located on the Main Engine Display which is always in view.
Additional EIS information can be viewed on the Eng Page which can be selected by touching the
Main Engine Display or by turning the 'Select Page' knob to the right on an MFD window.
Green bands on the instruments indicate normal ranges of operation; amber and red bands indicate
caution and warning, respectively. When unsafe operating conditions occur, the corresponding caution
readout will display solid amber and the warning readout will flash red. Most EIS caution and warning
conditions also generate an alert message on the PFD, including gauges that may appear only on the
Eng Page. An aural alert is also issued with a flashing red warning. If sensor data for an instrument
becomes invalid or unavailable, a red "X" is displayed across the instrument.

Communication / Navigation / Surveillance System

The Communication/Navigation/Surveillance
communication radios, navigation radios, and Mode S transponder. These functions can be accessed
from the boxes that make up the CNS Data Bar located at the top of the PFD and/or MFD.

Remote Transponder Interface

The G3X Touch is capable of interfacing with several remote transponders providing Mode S
interrogation and reply capabilities. Transponder tuning for panel mount transponders is also
supported.
Ground and Altitude Modes
Most Garmin transponders automatically transition between on-ground and in-air and operate in the
appropriate mode at all times. No pilot action is required to manage modes unless there is a need to
manually select STBY or ON modes.
G3X displays a green GND indication and transponder code in the Transponder Data Box while on-
ground, and a green ALT indication when in-air, when not set to STBY or ON.
Some panel mount transponders may indicate ALT on their dedicated display at all
times, even while on-ground.
display and G3X display will indicate different modes while on the ground, although
they are functionally equivalent.
Standby Mode (Manual)
When Standby mode is selected, the transponder does not reply to interrogations, but new codes can
be entered. A white STBY indication and transponder code appear in the Transponder Data Box.
Some transponders will automatically transition from STBY to ALT mode when the aircraft transitions
from on-ground to in-air.
