    3.4.3 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. Figure 3-7 and Figure 3-8 illustrate where the various configuration files are stored. Figure 3-7.

  • Page 46: Figure 3-8. Grs/Gdc Configuration Settings Storage

    The GRS 77 and GDC 74A configuration modules function differently than the rest of the system. The GDC 74A’s configuration file is loaded directly to GDC internal memory. A copy of the file is stored in the GDC configuration module. The GRS 77 configuration module does not store any configuration settings.

  • Page 47: Figure 3-9. Set>Actv Diagram

    In the first example shown in Figure 3-9, the SET columns do not match the ACTIVE columns. The inequality between SET and ACTIVE indicates a configuration mismatch. By pressing the SET>ACTV softkey, this copies the SET column to the LRU unit’s configuration memory. The settings then become the ACTIVE settings for the LRU being configured.

  • Page 48: Figure 3-10. Loss Of Communication

    When troubleshooting the system, technicians can look for inequalities between SET and ACTIVE columns. Certain problems can be resolved simply by pressing the SET>ACTV softkey, which reloads settings to the specific LRU from the PFD. (Note that this can also be accomplished by reloading the configuration files for the LRU, using the G1000 SW Loader Card.
