INDEX<br />

This annunciation is seen only<br />

when the autopilot is engaged.<br />

The annunciation indicates an<br />

AHRS monitor has detected<br />

an abnormal flight parameter,<br />

possibly caused by strong<br />

turbulence. In this case, the<br />

situation should correct itself<br />

within a few seconds. If there<br />

is an actual failure, a red “X”<br />

soon appears over the Attitude<br />

Indicator.<br />

GPS information is either<br />

not present or is invalid for<br />

navigation use. Note that<br />

AHRS utilizes GPS inputs<br />

during normal operation.<br />

AHRS operation may be<br />

degraded if GPS signals are not<br />

present (see POH).<br />

CDI is not receiving valid data<br />

from the corresponding GIA.<br />

Does not apply when the CDI is<br />

set to GPS.<br />

Display system is not receiving<br />

airspeed input from air data<br />

computer.<br />

Other Various Red X<br />

Indications<br />

Display system is not receiving<br />

altitude input from the air data<br />

computer.<br />

Display system is not receiving<br />

valid true airspeed information<br />

from air data computer.<br />

Display system is not receiving<br />

valid OAT information from air<br />

data computer.<br />

Display system is not receiving<br />

valid transponder information.<br />

Different versions of GDU<br />

software are installed in the<br />

PFD and MFD. This can also<br />

indicate different versions<br />

of the navigation database<br />

installed in the PFD and MFD.<br />

A cross-talk error between the<br />

PFD and MFD will also cause<br />

this annunciation.<br />

A red ‘X’ through any other<br />

display field (such as engine<br />

instrumentation fields)<br />

indicates that the field is not<br />

receiving valid data.<br />
