3.8.5 Configuration File Storage
The G1000 system is designed to store all configuration settings in various places so that the
configuration is retained in the aircraft during maintenance of units.
During system configuration, each file is sent directly to the applicable LRU where it is stored in local
LRU memory (reference Figure 3-14.). Each file is also stored in the PFD internal memory. The
applicable PFD also sends a copy of all configuration files to the ‘Master Configuration module’, located
in the connector backshell (see Section 6.16). If the PFD is replaced, the configuration module retains all
configuration files in the aircraft.
The GRS 77/7800, GMU 44, GDC 74B and optional GDC 7400 configuration/calibration (reference
Figure 3-15) is different than the LRU’s shown in Figure 3-14.
