3.5 G1000 Normal Mode
To start the G1000 system in Normal Mode:
1. With a ground power unit connected to the external power receptacle, set the BAT and EXT PWR
switches to ‘ON’. The following G1000 equipment is powered:
• PFD displays & MFD display
• GRS 77 or GRS 7800 AHRS Units
• GDC 7400 Air Data Computers
• GIA 63W Integrated Avionics Units
• GEA 71 Engine/Airframe Units
• GCU 477 FMS Control Unit
• GMC 710 Autopilot Control Unit
• GSA Servos
• GMA 1347D Digital Audio Panel #1
• GSD 41 Data Concentrator (Optional)
2. Set the AVIONICS MASTER switch to ‘ON’. The following G1000 equipment is powered:
• GMA 1347D Digital Audio Panel #2
• GDL 69A Datalink Unit
• GWX 68 or GWX 70 Weather Radar Unit
• GTS 820/850 Traffic System or GTS Traffic Processor (Optional)
• GTX 33 or GTX3000 Mode S Transponders (Optional)
• GDL 59 / GSR 56 Wi-Fi/Satellite (Optional)
• GRA 5500 Radar Altimeter (optional)
The G1000 system is now powered in the normal mode. In the normal operating mode, data fields that
are invalid have large red X’s through them. A valid field does not display a red X. Allow the displays
to initialize for approximately one minute. The GDC 7400s require a longer initialization period than do
the other LRUs. During normal operation, this causes the airspeed, altitude, vertical speed, and OAT
fields to be invalid during the first ~40-60 seconds of PFD power-up
. The PFDs and MFD will function
as specified in the G1000 300/B300 Series Cockpit Reference Guide when the system has been correctly
installed and configured.
