in ground mode and either thrust lever in
idle and airspeed below 40 knots).
• Completion of landing (transition from
air to ground mode plus 30 seconds).
• Aborted landing (radio altitude above 400
feet).
This mode may also be deactivated by:
• Radio altimeter invalid.
• Indicated airspeed invalid.
AURAL WARNINGS
Aural warnings consist of audio tones and
voice messages generated by the CWP. The ex-
ception is the trim-in-motion clacker audio,
which is provided to the audio system for am-
plification. Aural warnings are detailed in
Table 4-1. Some aural warning messages are
preceded by a triple chime and flashing of the
master WARN lights. Aural caution messages
are preceded by a single chime and flashing
master CAUT lights. The chimes and voice
messages are sounded to both pilot’s head-
phones and cockpit speakers. Note that some
of the aural warnings are mutable and others,
of more critical significance are not (Table 4-
1). Those audio tones and voice messages that
are mutable are silenced by depressing the
mute button, located on the outboard side of
the right engine thrust lever handle (Figure 4-
4 ) , o r b y d e p r e s s i n g e i t h e r m a s t e r
WARN/CAUT light. For non-cancelable aural
warnings, the voice message continue to re-
play until the condition that tripped the warn-
ing is no longer valid.
Failures of the audio warning system are an-
nunciated by an amber “WARN AUDIO” CAS
message. This indicates a total failure of the
audio warning system, to include the master
warning and master caution chime. Should this
same message be white, it indicates a minor
fault was detected and the audio has defaulted
to high gain. The CWP indicators and CAS
messages are still operational in this case.
TAKEOFF
CONFIGURATION
MONITOR
The takeoff configuration monitor system is
used in conjunction with the crew warning
system to provide both visual and aural alerts
when an unsafe airplane configuration exists
during the takeoff phase of flight.
For example, when the airplane is on the
ground, a white “TAKE-OFF TRIM” mes-
sage annunciates within the CAS window if
the pitch, aileron or rudder trims are not in a
safe position for takeoff. This message flashes
for approximately 5 seconds, then resets au-
tomatically to a steady state. If the out-of-trim
condition has not been corrected prior to ad-
vancing the power for takeoff, the “TAKE-
OFF TRIM” CAS message turns red, the triple
chime sounds and the “CONFIGURATION”
voice message sounds.
The “CONFIGURATION” voice warning is ac-
tivated during ground operations when either
thrust lever is advanced to MCR or above and
one or more of the following seven conditions
also exist:
