• Full-Screen PFD/MFD Configuration (Reversionary Mode)
In the event of a display failure, the G3X System automatically switches to
reversionary (backup) mode. In reversionary mode, all flight information is presented
on the remaining display in the split-screen configuration.
If a display failure occurs with the GDU 375, the WX and XM Pages will no longer
be available since the XM receiver resides in the GDU 375.
