4.3 Crosscheck Monitor
Figure 16. Crosscheck Monitor
The Envision EXP5000 comes equipped with a self-check monitor.
When this monitor detects a condition that does not warrant removal
of data, a CROSSCHECK ATTITUDE warning message displays.
When this message is displayed, scan all backup instruments and
auxiliary instruments (backup attitude indicator, backup airspeed
indicator, and back up altimeter) to crosscheck the aircraft attitude.
The warning message is automatically removed when the self-check
monitor confirms the EXP5000 attitude is valid.
The message will not be displayed when air data is invalid (as shown
on page 58). Cross referencing the EXP5000 attitude to the backup
ADI is recommended during flight with invalid air data.
!
For aircraft equipped with a 55X autopilot, if a CROSSCHECK
ATTITUDE alert displays on the PFD, Avidyne strongly
recommends using Autopilot (not HDG mode).
Note
: Highly dynamic maneuvering such as multiple linked lazy-8 leaves
may result in small pitch and/or bank errors. If the errors build up to an
excessive amount, the crosscheck attitude message may display.
Note:
In dual PFD installations, the CROSSCHECK ATTITUDE message
applies to the selected ADAHRS source.
