Annunciations & Alerts

10.3 AURAL ALERTS

• "Five Hundred"—when the aircraft descends through 500 feet above the destina-

The following aural terrain alerts are issued when flight conditions meet
parameters that are set within the software algorithms, and are dependent on

10.4 PFD ANNUNCIATIONS AND ALERTING
FUNCTIONS
The following annunciations and alerting functions are displayed on the PFD.

UNCERTAIN HEADING

If the G3X senses that the magnetic heading measurement is valid, but possibly
outside of the internal accuracy limits, the numeric heading value on the PFD is display
in yellow. When the system heading is uncertain, features that use heading data may
not be available (e.g., autopilot HDG mode or PFD wind calculations). An uncertain
heading value can be caused by magnetic anomalies or installation/calibration issues.
Refer to the G3X installation manual for installation and calibration information for
the magnetometer
