Line Replaceable Units (LRU)

This guide covers the operation of the GDU 620 display as integrated in the
G500 system. The G500 Avionics Display System is an avionics suite designed
to replace the traditional flight instrument cluster. The system combines
primary flight instrumentation, navigational information, and a moving map all
displayed on dual color screens. The G500 system is composed of sub-units or
Line Replaceable Units (LRUs). LRUs have a modular design and can be installed
directly behind the instrument panel or in a separate avionics bay if desired.
This design greatly eases troubleshooting and maintenance of the G500 system.
A failure or problem can be isolated to a particular LRU, which can be replaced
quickly and easily. Each LRU has a particular function, or set of functions, that
contributes to the system' s operation.
