APPENDIX A
VOICE ALERTS
The following audio alerts are announced by the system using a voice of male or female gender (see the AUX
- System Setup Page for the default configured voice gender; contact a Garmin-authorized service center to
change the audio alert voice). If the optional Terrain Awareness and Warning System is installed, voice alerts
are also generated (refer to the TAWS Alerts section).
Voice Alert
"Minimums, Minimums" Issued when the aircraft transitions through the minimum descent altitude/decision height (MDA/DH)
"Vertical Track"
"Traffic"
"Traffic Not Available"

COMPARATOR ANNUNCIATIONS

The Comparator monitors critical values generated by redundant sensors. If differences in the sensors exceed
a specified amount, this discrepency is annunciated in the Comparator Window as a 'MISCOMP' (miscompare)
as seen in Figure A-1. If one or both of the sensed values are unavailable, it is annunciated as a 'NO COMP' (no
compare). The following is a list of the possible annunciations:
