Reversionary sensor selection is annunciated in a window on the right side of the PFD. These annunciations
reflect reversionary sensors selected on one or both PFDs. Pressing the SENSOR Softkey accesses the ADC1,
ADC2, AHRS1, and AHRS2 softkeys. These softkeys allow switching of the sensors being viewed on each
PFD. With certain types of sensor failures, the G1000 may make some sensor selections automatically. The GPS
sensor cannot be switched manually.
