    _________________________________________________________________ The GDU 1xxx is the most visible portion of the G1000. In a two display installation, one GDU is configured as a Primary Flight Display (PFD), the other is configured as the Multi-Function Display (MFD). The MFD displays navigation information and engine/airframe instrumentation. The PFD displays primary flight information in place of traditional gyro systems.

  • Page 19: Gdc 74(X) Air Data Computer

    _________________________________________________________________ The GIA is the central ‘Integrated Avionics Unit’ (IAU) to the G1000 system. The GIA functions as a main communications hub. The GIA contains the GPS receiver, VHF COM/NAV receivers, and system integration microprocessors. The GIA communicates directly with the displays using a HSDB Ethernet connection.

    _________________________________________________________________ 3.1 G1000 FLIGHT INSTRUMENTATION The GRS 77 AHRS, GDC 74(x) Air Data Computer, and GMU 44 Magnetometer provide the G1000 system with flight instrument data consisting of aircraft attitude, heading, yaw rate, altitude, airspeed, vertical speed, and outside air temperature information. This information is displayed on the PFD (and also on the MFD when it is in reversionary mode).

  • Page 27: G1000 Engine Indication System

    From there, data is sent through the HSDB connection to the PFD, then on to the MFD for display. A backup data path exists in the event the primary path fails. Figure 3-3. Basic G1000 Engine Indication System G1000 System Maintenance Manual...

The update is expected to be available from Garmin by July 1 of each of the following years: 2005, 2010, 2015, and every five years thereafter, as long as the GRS remains a Garmin-supported product. Otherwise maintenance of the GRS is on condition of failure only.

  • Page 183: Section 10-System Reconfiguration

    The GRS and GMU Magnetometer LRUs do not use configuration files. However, these LRUs do require several calibrations during installation and/or maintenance. The G1000 loader card contains the configuration files listed below (this list is an example, it can differ depending on the requirements of a specific installation): •...
  • Page 184 If the PFD is replaced, the configuration module retains all configuration files in the aircraft. The G1000 stores all configuration settings in various places so that the configuration of the system is retained in the aircraft during maintenance.

  • Page 185: Initial Software And Configuration Overview

    The steps listed below describe the software and configuration upload that took place at the time of the initial installation as explained in the G1000 installation manual. 1. Software is first loaded to the MFD and then the PFD. G1000 systems do not contain any usable software or configuration files from the factory.

  • Page 186: G1000 Software And Configuration Upload

    G1000 SOFTWARE AND CONFIGURATION UPLOAD NOTES Do not remove power from the G1000 during software loading. Do not rely solely on the aircraft batteries to prevent loss of power during the software loading process, connect a ground power unit to the aircraft. All GDUs should be in the same mode (configuration or normal), unless instructed differently by the procedure.
  • Page 187 (detailed below) will be overwritten by the base airframe configuration if the optional system configuration is completed first. 1. Insert the proper G1000 loader card into the top card slot of the PFD. 2. Press and hold the ENT key on PFD while applying power.

    GDU. Updating the Jeppesen aviation database: 1. With the G1000 System OFF, insert the SD card containing the aviation database update into the top card slot of the PFD to be updated (label of SD card facing left).

  • Page 196: Miscellaneous G1000 Databases

    G1000 topography, terrain, airport terrain, and obstacle data is stored on a supplemental data card provided by Garmin. The obstacle database update cycle is every 56 days. The terrain and airport terrain database is updated less often, and on an irregular basis. Since these databases are not stored internally in the MFD or PFD, supplemental data cards containing identical database versions must be kept in both displays to retain terrain and obstacle data.

  • Page 197: Updating Garmin Databases

    • Existing supplemental data cards from both PFD and MFD In some cases it may be necessary to obtain an unlock code from Garmin in order to make the database product functional. It may also be necessary to have the system configured by a Garmin authorized service facility in order to use some database features.
