6.4 LOSS OF DATA
In general, a flashing yellow mode annunciation
indicates either the loss of sensor data (AHRS, ADC,
or GIA) or loss of navigation data (VOR, LOC, or GPS)
required to compute commands.
When such a loss occurs, the system automatically
reverts to the default mode for the affected axis (ROL for
roll axis, PIT for pitch axis). The flashing annunciation
stops when the pilot presses the affected mode button or
selects another mode for the axis. If no pilot action is
taken, the flashing annunciation stops after ten seconds.
