1.4.10 Configuration Files
A G1000 Loader Card typically contains the following 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 a specific
airframe.
•
SYSTEM: This file configures the G1000 Ethernet to communicate with a PFD, MFD, and GIAs.
•
MANIFEST: This file loads a manifest of all software part numbers and versions associated with an
approved system configuration.
•
MFD1: This file configures the MFD serial/discrete communications and alerting system settings.
•
PFD1: This file configures the PFD serial/discrete communications and alerting system settings.
•
GIA1/GIA2: These files configure GIA1 and GIA 2 serial/discrete communications settings.
•
GMA1: This file configures the GMA 1347 audio and serial communications settings.
•
GTX1: This file configures the GTX transponder and serial communications settings.
•
GEA1: This file configures GEA 71 engine/airframe parameters.
•
GDC1: This file configures the GDC 74A air data values.
•
GDL69: This file configures the GDL 69A serial communications settings
•
CALIBRATION: This file configures calibration values for various analog sensors connected to the
GEA (fuel quantity, fuel flow, etc.)
•
AUDIO: This file configures all of the audio messages for the G1000 system. This includes both
tones and voice messages that are utilized for alerts, cautions, and warnings.
The above files are loaded during the configuration process. Each file is sent directly to the applicable LRU. The
same file is also stored into PFD internal configuration memory and configuration module. If the PFD is
replaced, the configuration module retains all configuration files in the aircraft.
The GRS 77 AHRS and GMU 44 Magnetometer do not utilize a configuration file. However,
these LRUs do require several calibrations during installation and/or maintenance.
