Single MFD with G5
The G5 seamlessly integrates with other G5 units in the same aircraft and with G3X systems via the CAN network. When installed as part of a G3X system, the G5 provides a redundant source of attitude and air data to the G3X displays,
and additionally provides backup autopilot control allowing coupled GPS approaches to be flown or continued in the event that the primary flight display is unavailable. When installed as a standalone system, the G5 can also perform the autopilot function. In the case of aircraft power loss, the optional battery backup sustains the G5 flight display with up to 4 hours of emergency power.
If a GDU (MFD) is connected to the CAN-bus, the G5 will by default be a backup to the G3X-system. You need to spek with the G3XExperts about this.
