G1000 Supplemental Maintenance Manual Page 4-6Textron Nav III Series Revision 3190-02128-04Electrical Bonding ProcedureUsing one of the two measurement methods in Section 4.4.2 record the bonding measurementfor the following equipment. Some equipment in the list is optional and may not be installed.Ensure that the PFD unit, and MFD unit test points, no more than 40 mΩ is present. Ensurethat at other unit test points, no more than 5 mΩ is present.Pilot Compartment• Metal case of PFD: __________ mΩ• Metal case of MFD: __________ mΩ• GDL 69A body (182 and 206 only): __________ mΩRear Fuselage and Empennage• GDL 69A body (172 only): __________ mΩ• GSU 75 body: __________ mΩ• GTX 335R or GTX 345R body: __________ mΩ4.5 GSU 75 Earth Magnetic Field UpdatesThe GSU 75, utilizes an Earth magnetic field model which is updated once every five years.The update is expected to be available from Garmin every five years, as long as the GSU 75,remain Garmin-supported products.The G1000 system alerts the operator that the magnetic field database is out of date by issuingthe message “AHRS SERVICE – AHRS Magnetic-field model needs update”. Garmin willdistribute updates as part of the navigation database cycle. If the IGRF model in the update isnewer than the model installed, a prompt will appear for each GRS/GSU (Select “OK” to updatethe IGRF Magnetic Field Model). Use the FM Knob and ENT key to select “OK”.4.6 G1000 Redundant Connection CheckPerform the following steps to verify the following:(A) The primary (PRI) and secondary (SEC) power sources for the PFD, GSU (if installed) orGDC and GRS (if installed).(B) The GSU (if installed) data path to PFD and MFD.Note: Section B is not required if a GSU 75 is not installed. Refer to the Cessna Nav III LineMaintenance Manual for procedures if a GDC 74A and GRS 77 are installed..(A) PRI and SEC power sources for PFD and GSU (if installed) check1. Connect a ground power unit to the external power receptacle and turn on the groundpower unit.2. Set the BAT and AVIONICS MASTER PWR switches to ON. |
