ERR# TEXT MESSAGE(S)
DESCRIPTION OF ERROR
91 Lat cpld invalid
The roll coupled mode has been deactivated due to invalid inputs that prevent
proper algorithm calculation. If the selected mode is HDG hold, loss of HDG
valid for 3 seconds will dump the roll coupled mode. If the selected mode is
GPS TRK, loss of NAV valid for 5 seconds or HDG valid for 5 seconds will dump
the roll coupled mode. If the selected mode is LOC TRK, loss of NAV valid for
5 seconds or HDG valid for 5 seconds will dump the roll coupled mode. If the
selected mode is VOR TRK, loss of NAV valid for 5 seconds or HDG valid for
15 seconds will dump the roll coupled mode. If the selected mode is the default
lateral coupled mode and CWS is not pressed, loss of rate valid from the Turn
and Bank Indicator for 1 second will dump the roll coupled mode.
92 Vert armed #1 invalid
The altitude arm mode has been deactivated due to invalid inputs that prevent
proper algorithm calculation. If the KC 140 Analog valid signal is invalid
for 0.5 seconds the altitude arm mode will be dumped.
93 Vert armed #2 invalid
The Glideslope arm mode has been deactivated due to invalid inputs that prevent
proper algorithm calculation. If the Glideslope (GS) valid signal is invalid
or the accelerometer monitor has failed or the ILS sensor is no longer selected
for 10 seconds the glideslope arm mode will be dumped.
94 Vert cpld invalid
The pitch coupled mode has been deactivated due to invalid inputs that prevent
proper algorithm calculation. If the selected mode is GS TRK, loss of the GS
valid signal or an acceleration failure or not having the ILS selected for
3 seconds will dump the pitch coupled mode. If the selected mode is the default
vertical coupled mode, loss of the KC 140 Analog valid signal for 1 second
will dump the pitch coupled mode.
95 Roll invalid
The roll autopilot has been deactivated due to invalid inputs that prevent
proper algorithm calculation. The default roll attitude hold mode will be dumped
if the KS 271C roll valid signal is invalid for 1 second or the rate valid
signal from the Turn & Bank indicator is invalid for 1 second without CWS being
pressed.
