the two outboard flight spoilers.) The malfunction annunciations are
depicted in Figure 22.
NOTE:
Failure of the automatic deployment of ground spoilers
does not preclude operation of the spoiler panels
manually. Extending the SPEED BRAKE handle will
deploy all spoiler panels to thirty degrees (30°) - less
than the full fifty-five degrees (55°) with automatic
operation, but still effective in slowing the aircraft.
At any time the left main landing gear is locked in the down position (inflight
or on the ground) and the GND SPLR pushbutton switch is not in the
ARMED position (amber OFF legend within the switch illuminated), a blue
advisory CAS message reading “Ground Spoiler Unarm” is displayed. The
same message will be displayed if a malfunction in the logic arming
circuitry prevents operation of automatic ground spoilers with the GND
SPLR switch selected to ARMED (amber ARMED legend illuminated in the
switch).
D. Malfunction Monitoring Infight:
The uncommanded deployment of a spoiler panel during flight may cause
structural damage or seriously degrade the stability of the aircraft. If the
SPEED BRAKE handle is in the forward stowed position and the GND
SPLR switch is not armed, or if the switch is armed in preparation for
landing but the aircraft is not yet on the runway, and one or both of the
ground spoiler panels is not in the stowed position (sensed by the contact
switches), the red “Ground Spoiler” CAS message will be displayed along
with illumination of the Master Warning glareshield lights and aural warning
tones.
The MWS will also generate a red “Ground Spoiler” warning if conditions
are detected that could cause an uncommanded spoiler activation. Areas
sampled are the same as those described during takeoff and landing with
the addition of fault monitoring of the WOW switches and wheel speed
circuits.
Removing hydraulic power to the spoilers by pulling the SPLR FLT PWR
S/O circuit breaker on the copilot overhead panel will bypass all hydraulic
pressure in the ground and flight spoiler actuators and allow aerodynamic
pressures to stow the extended spoiler panel. See 05-13-60, Ground
Spoiler Failure Inflight..
E. Ground Spoiler Test Switch:
A GND SPLR TEST switch is located on the cockpit center console above
the GND SPLR ARMED / OFF pushbutton as shown in Figure 22.
Depressing and holding in the switch will illuminate the amber IN TEST
legend in the switch and test the following indications:
•
Both NO GND SPLRS red lights on the windshield center post will
illuminate
•
A red “Ground Spoiler” warning message is displayed on the CAS
window
•
The red Master Warning glareshield light and aural warning tones
