Figure 2-11 – G3X Architecture (Summary)
Notes:
(1) Backup instruments for a G3X PFD installation may be either a G5 ADI or pneumatic instruments
(vacuum AI, airspeed indicator, altimeter). If GFC500 is installed with a G3X PFD, a G5 is not
required if a Sonalert is installed.
(2) HSDB & RS232 Connext interfaces are only applicable with GNX 375 or GTX 345() to support
FIS-B weather & TIS-B traffic display on GTN & GDUs.
(3) Maximum of two (2) COM/NAV units installed.
(4) GAD 27 required for 14v airframes with EIS and may optionally be connected to PFD and GSU
25D in 14v airframes without EIS.
