PAGE 41
3.7 Configuration Mode Overview Throughout this document, references are made to the PFD1, PFD2 and/or MFD being in configuration mode. The configuration mode exists to provide the avionics technician with a means of configuring, checking, and calibrating various G1000 sub-systems. Troubleshooting and diagnostics information can also be viewed in this mode. To start the G1000 system in configuration mode, follow these steps: 1.
PAGE 42
Data can be manually copied from one column to the other (and consequently from PFD memory to the LRU memory and vice-versa) by using the following two softkeys, when available: • SET>ACTV (read ‘Set to Active’) softkey: Allows the installer to send the information in the SET column (data stored in the master config module) to the ACTV column (data used by LRU). • ACTV>SET (read ‘Active to Set’) softkey: Causes the LRUs current settings to be copied to the master configuration module as SET items.
PAGE 43
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. Section 7 describes this process for each LRU). A blank active column, as shown in Figure 3-11, represents loss of communication between the display and the particular unit.
PAGE 44
3.7.4 Configuration Mode Navigation Using the FMS knob as described in Section 3.1.2, a user can navigate through different pages and page groups in the Configuration Mode. For complete description and breakdown of each page, refer to the G1000 System Maintenance Manual listed in Table 1-3. System Page Group 1. System Status 5. System Upload 9.

NOTE When the extraction begins, the program automatically deletes all current files on the SD card and copies the selected files to it, regardless of the file format on the SD card. Ensure files are not necessary, or card is empty before proceeding.
PAGE 48
8. Ensure the card and correct drive letter is used, and click next. Select drive 9. A window will pop-up onto the screen to indicate file progress.
PAGE 49
10. Once successfully completed, the following message/window will pop-up. Click Finish to finalize SD card. 3.8.3 Software Files Software files are defined by part number and version number on the General Arrangement drawing. See Table 1-2 for the correct General Arrangement drawing part numbers. Each G1000 / GFC 700 LRU reports the software version it currently contains to the user in two places. • Normal System Mode: The AUX – SYSTEM STATUS page lists each LRU and the reported software version.
PAGE 50
3.8.5 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. During system configuration, each file is sent directly to the applicable LRU where it is stored in local LRU memory (reference Figure 3-14.). Each file is also stored in the PFD internal memory.
PAGE 51
The GRS 77 AHRS and GMU 44 Magnetometer do not have a configuration file. However, the GRS77 does store calibration data acquired during the post installation checkout, which are characteristic to the specific installation. A copy of this calibration data is stored in the GRS 77 configuration module. While performing maintenance on these units, re-calibration may be required. See Section 7.7.1 for more information on re-calibration criteria.
PAGE 52
3.9 G1000 Software/Configuration Procedure This section summarizes the procedures required to load software and configuration files to the G1000.

PAGE 259
NOTE Due to the difficulties in executing smooth, accurate turns the PFD may incorrectly interpret a station and instruct to “HOLD POSITION” prior to full completion of a 30° turn. If this scenario is encountered, it is best for the operator to ignore the “HOLD POSITION” command and instead use outside references to complete the approximate 30° turn.
PAGE 260
7.7.5 Procedure D: Engine Run-Up Vibration Procedure NOTE Calibration Procedure D is performed in order to guarantee that the AHRS mounting is sufficiently rigid and insensitive to vibration. This procedure must be performed for both GRS 77 units installed in the aircraft. Calibration Procedures A1 and B (Sections 7.7.2 and 7.7.4 respectively) are not required prior to this procedure. Figure 7-6, Engine Run-Up Test Page 1. Press the FMS small knob to highlight GRS 77 #1.
PAGE 261
NOTE Should a failure occur, the technician may perform the Engine Run-up test up to 3 times successively before corrective action must be taken. If the test does not pass after three attempts, then the installation should not be considered reliable until the source of the vibration problem is identified and remedied. In the event of repeated failure of the engine run-up test, record the values that are reported to be out of range for future reference.
