3.8.4 Configuration File Descriptions
Configuration Files are divided into groups, and are only displayed at the System Upload page during the
software/configuration loading process. There are five categories of configuration files:
C90
C90-Options
C90-Configurations
C90-Configurations 2
C90-Weight and Airspeed
Configuration files contain preset selections for input/output channels, aircraft-specific settings, and
LRU-specific settings. The following list describes each of the configuration files:
AIRFRAME This file contains data such as airspeed parameters, engine/airframe sensor
limitations, fuel tank parameters and alerting system settings that tailor a
G1000 PFD or MFD to the C90A/GT/GTi.
AIRFRAME C90A/GT/GTi-specifc alerts are set when this file is loaded.
ALERTS
SYSTEM This file configures the G1000 high-speed data bus (HSDB) to expect two
PFDs, MFD, two GIAs, and a GDL69.
MANIFEST This file loads a manifest checklist of all software part numbers and versions
associated with an approved system configuration. The G1000 performs a
software check between each LRU’s reported version and the version
contained on the manifest. If an inequality is detected for an LRU, this LRU is
then excluded from the G1000 and a manifest alert is triggered to the operator.
MFD1 This file configures MFD serial/discrete communication and alert system
settings.
PFD 1/PFD 2 These files configure PFD 1/PFD 2 serial/discrete communication and alert
system settings.
GCU This file configures GCU 475 serial/discrete communication settings.
GMC This file configures GMC 710 serial/discrete communication settings.
GIA1/GIA2 These files configure GIA1/GIA2 serial/discrete communication settings.

GMA_COPIL for both audio panels.
GTX1/GTX2 These files configure GTX 1/GTX 2 transponder and serial communications
settings.
GEA1/GEA2 These files configure GEA 1/GEA 2 engine/airframe parameters.
GDC_PIL/ This file configures GDC 74B air data values for the C90A/GT/GTi.
GDC_COPIL
GDL_69 This file configures gains and cable loss for the C90A/GT/GTi installation.
GWX This file configures parameters as appropriate for the C90A/GT/GTi radar
installation.
AUDIO This file configures audio alerts for the C90A/GT/GTi.
