FlightSafety LEARJET 45 - Primary Flight Display (PFD)

When a system parameter miscompare be-
tween Channel A and B of it’s on-side DAU,
the respective CAS message "L R DAU SYS
MISCMP" will be displayed.
The IC-600 is also designed to receive and
process signals from each of the display units.
This is a cross-check of what is actually being
displayed on-screen vs. a comparison check
of what is the source of the displayed data.
Should data from the below listed items be out
of tolerance between what is being reported
from the source, and what is being sent to the
display units, a respective amber "L R PFD
CHECK" message will illuminate on the CAS.
• Pitch
• Roll
• Barometric Altitude
•Mach
• Indicated Airspeed
• Baro Set (in-hg)
• Baro Set (hPa)
Engine information being displayed is mon-
itored against the actual DAU’s sensor data.
The IC-600 that is not displaying EICAS per-
forms the comparison function for the fol-
lowing:
•N1
•N2
•ITT
Should exceedances be detected a “CHK
EICAS” message is displayed on the MFD by
the CAS (Figure 16-38).
