3.2.1.1 Reversionary Mode
In a dual display installation, a reversionary display mode is supported in the event of GDU failure. When
two GDUs are installed, one as PFD and the other as an MFD, the system will automatically revert the
functioning GDU to a reversionary format in the event of a GDU failure. In the reversionary mode,
primary flight information, radio tuning information and EIS (if installed) are displayed on the remaining
GDU.
3.2.2 Configuration Mode Overview
Throughout this document, references are made to the GDUs being in configuration mode. The
configuration mode exists to provide the avionics technician with a means of configuring, checking, and
calibrating various G3X Touch system.
To enter configuration mode:
1. Hold down the "MENU" key on the GDU 4X0 while applying power to the aircraft, until the display
shows "Configuration Mode" text.
