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 switch to ‘ON’.
The following G1000 equipment is powered:
• PFD displays & MFD display
• GRS 77 AHRS Units
• GDC 74B or 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
2. Set the AVIONICS MASTER switch to ‘ON’. The following G1000 equipment is powered:
• GTX 33 Mode S Transponders
• GMA 1347D Digital Audio Panels
• GDL 69A Datalink Unit
• GSA Servos
• GWX 68 Weather Radar Unit
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 74Bs requires 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 200/B200 Series Cockpit Reference Guide when the system has been correctly
installed and configured.
