6.9. ADAHRS Attitude Disagreement
Should dierences be observed between one or more EFD1000 displays and/or the
standby instruments, monitor all available attitude, airspeed, and altitude information to
diagnose faulty indicator(s). Reset the EFD1000 ADAHRS.
6.10. In-Flight ADAHRS Reset
In the unlikely event the EFD1000 determines a potential degradation of attitude
information, a warning annunciation, CROSS CHECK ATTITUDE, displays (Figure 6-9). If
the attitude pitch or roll data become invalid, a red “X” and the textual annunciation of
“ATTITUDE FAIL” display on the Secondary Attitude Indicator and all aircraft roll, pitch,
and slip information is removed from the Attitude Indicator display (Figure 6-10). Use
alternate, mechanical, ight instruments and reset the AHRS as soon as possible.
