1.1 G3X TOUCH GNSS (GPS/SBAS) NAVIGATION EQUIPMENT
APPROVALS
To support IFR navigation the G3X Touch must be interfaced to a compatible Garmin GPS or VHF
navigator including the following:
•
GNC 300XL / GPS 155XL *
•
GNS 4XX(W) / GNS 5XX(W) / GNS 480 *
•
GTN 6XX / 7XX *
•
GPS 175 / GNX 375 *
•
SL30
•
GNC 255
•
GNC 355/355A *
* requires installation of GAD 29B ARINC-to-CAN converter
In lieu of interfacing G3X Touch to a Garmin IFR navigator, an installation could maintain IFR capability
by retaining non-Garmin GPS and/or VHF Nav radios along with their standalone dedicated CDI.
NOTE
Refer to the Airplane Flight Manual Supplement for the installed IFR approved GNSS
Navigation System for approved operations.
When no external IFR navigator is connected, or when the internal G3X Touch GPS navigation source
is selected by the pilot, the G3X Touch provides VFR flight planning capabilities and guidance on the
HSI. A cyan
‘INT’ and magenta ‘VFR’ annunciation are displayed on the HSI when using the internal
navigation function.
When ‘INT’ and ‘VFR’ are annunciated, IFR operations are prohibited.
