Display Units (DU)
The GIV system contains six color display units as shown in Figure
201. The DU is the media by which flight data is conveyed to both
the pilot and copilot.
Display Controllers (DC)
The GIV display system contains two display controllers. The DCS
are used to control the various display unit formats. Basically,
each pilot can control the formats for the on-side PFD and ND
displays in addition to the ENGINE and CAS displays.
Symbol Generators (SG)
The GIV display system has three symbol generators, each one
containing the four formats described in paragraph 2.A. The purpose
of the SG is to supply all the displayed data to the individual
display units in the system.
Each symbol generator has the
capability to drive all six display units in the event the other two
fail. With two or three SGS operational, all six display units have
unique formats displayed. With one SG operational, the
Copilot's
displays (PFD and ND) are repeaters of the pilot's displays.
Normally (3 SGS operational), SG 1 drives the pilot's displays, SG 2
drives the copilot's displays, and SG 3 drives the EICAS displays.
