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 for the red X's to be removed.
The GDC 7400 air data computers may require a longer initialization period than other G1000
units. This longer initialization period may cause the airspeed, altitude, vertical speed, and OAT
fields to be invalid during PFD power-up which is normal until the GDC 7400 units are
initialized
.
The PFDs and MFD will function as specified in the G1000 Cockpit Reference Guide when the
system has been correctly installed and configured.
