CONFIGURATION FILES

The GRS 77 AHRS and GMU 44 Magnetometer LRUs do not use
configuration files.
calibrations during installation and/or maintenance.
The G1000 Loader Card contains the following configuration files (this list is nonspecific and
can differ depending on the requirements of a particular installation):
AIRFRAME―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―configures the G1000 Ethernet to communicate with a PFD, MFD, and GIAs and
•
other LRUs that support HSDB.
MANIFEST―uploads a manifest of all software part numbers and versions associated with
•
an approved system configuration.
MFD1―configures the MFD serial/discrete communications and alerting system settings.
•
PFD1/PFD2―configures PFD serial/discrete communication and alert system settings.
•
GIA1/GIA2―these files configure GIA1/GIA2 serial/discrete communication settings.
•
GMA1/GMA2―configures GMA audio and serial communication settings.
•
GTX1/GTX2―configures GTX transponder and serial communications settings.
•
GEA1/GEA2―configures GEA engine/airframe parameters.
•
GDC1/GDC2―configures GDC air data values for the aircraft.
•
GDL69―configures GDL 69/69A data link and communications settings.
•
GMC―configures the GMC 710.
•
GCU―configures the GCU 475.
•
CALIBRATION―configures the fuel and trim calibration data.
•
GWX―configures the GWX 68 weather radar settings.
•
AUDIO―configures all of the audio messages for the G1000 system including tones and
•
voice messages.

4.4.1 Configuration File Retention

The G1000 stores all configuration settings in various locations allowing the configuration of the
system to be retained in the aircraft during maintenance. Since the G1000 is installed in a
variety of aircraft, it is imperative that aircraft specific data be retained at the aircraft level.
Figures 4-4 and 4-5 illustrate a block diagram of how a typical G1000 stores configuration
settings.
The GRS 77 and GDC 74B configuration modules function differently than the rest of the
system. The GDC 74B's configuration file is loaded directly to GDC internal memory, a copy is
also stored in the GDC configuration module. The GRS 77 configuration module stores
calibration data recorded during installation calibration procedures and does not store
configuration settings.
