2.3 PFD Annunciationsnnunciations and Alerting Functions
The following annunciations and alerting functions are displayed on the PFD. Refer to the EICAS Section for information on the Crew Alerting System (CAS) and to Appendix A for more information on alerts and annunciations.
Systemystem Alerting
The System Messages Window conveys messages to the flight crew regarding problems with the G1000 System. When a new message is issued, the MSG Softkey flashes to alert the flight crew. It continues to flash until selected, which opens the System Messages Window and acknowledges the message(s) which initiated the flashing. When the window is open, messages for which the trigger conditions no longer exist turn gray. Messages generated while the window is open are not automatically displayed, but cause the MSG Softkey to begin flashing again. Pressing the MSG Softkey while the System Messages Window is open closes the window, unless the MSG Softkey is flashing.
Critical values generated by redundant sensors are monitored by comparators. If differences in the sensors exceed a specified amount, the Comparator Window appears in the upper right corner of the PFD and the discrepancy is annunciated in the Comparator Window as a MISCOMP (miscompare). If one or both of the sensed values are unavailable, it is annunciated as a NO COMP (no compare).
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.

Marker BeaconBeacon Annunciationsnnunciations
Marker Beacon Annunciations are displayed on the PFD to the left of the Selected Altitude. Outer marker reception is indicated in blue, middle in amber, and inner in white. Refer to the Audio Panel and CNS Section for more information on Marker Beacon Annunciations.

Traffic Annunciationnnunciation
The G1000 System displays traffic symbolically on the Inset Map (PFD), the Navigation Map Page (MFD), and various other MFD page maps. Refer to the Hazard Avoidance Section and Appendix F for more details about the Traffic Information Service (TIS). When a Traffic Advisory (TA) is detected, the following automatically occurs:
• The PFD Inset Map is enabled, displaying traffic
• A flashing black-on-yellow TRAFFIC annunciation appears to the top left of the Attitude Indicator for 5 seconds and remains displayed until no TAs are detected in the area
• A single “TRAFFIC” aural alert is generated
If additional TAs appear, new aural and visual alerts are generated.
TAWS Annunciationsnnunciations
Terrain Awareness and Warning System (TAWS) annunciations appear on the PFD to the upper left of the Altimeter (also where the marker beacon annunciations appear). Refer to the Hazard Avoidance Section and Appendix A for information on TAWS alerts and annunciations.

Minimum Descent Altitudeltitude/Decision Height Alerting
For altitude awareness, a barometric Minimum Descent Altitude (MDA) or Decision Height (DH), based on barometric altitude can be set. When active, the altitude setting is displayed to the lower left of the Altimeter and with a bug at the corresponding altitude along the Altimeter (once the altitude is within the range of the tape).
The following visual annunciations alert the pilot when approaching the MDA or DH:
• When the aircraft altitude descends to within 2500 feet of the MDA/DH setting, the BARO MIN box appears with the altitude in light blue text. The bug appears on the altitude tape in light blue once in range.
