REVERSIONARY SENSOR ANNUNCIATIONS
Reversionary sensor selection is annunciated in the Reversionary Sensor Window, as shown in Figure A-5.
These annunciations reflect reversionary sensors selected on one or both PFDs. Pressing the SENSOR Softkey
gives access to ADC1 , ADC2 , AHRS1 , and AHRS2 Softkeys. These softkeys allow manual switching of sensors. In
the case of certain types of sensor failures, the G1000 may make some sensor selections automatically. The GPS
sensor cannot be switched manually.
