Elevator Trim System Check OM 2A-27-20
Located on the pilot’s flight panel, the PITCH TRIM ENG / DISENG
switch engages or disengages the electric pitch trim. Pitch trim is also
engaged whenever the autopilot is engaged. With electric pitch trim
engaged (amber DISEN switch legend extinguished), pitch trim can be
adjusted through use of a split-half pitch trim switch installed on the
outboard grip of each control wheel.
Inadvertent actuation of pitch trim, including runaway, is minimized
through the split-half switch design. In order for the pitch trim to be
actuated, both halves of the switch must be simultaneously moved in
the same direction.
During the Before Starting Engines checklist on the first flight of the
day, run the elevator trim fully up and fully down using both halves of
the switch simultaneously. Next, attempt to run the pitch trim using
each half of the switch independently. Any movement resulting from
using either half of the switch independently indicates a malfunction
that should be corrected before flight. Finally, set pitch trim for the
takeoff Center of Gravity (CG) condition as determined using the
Recommended Elevator Trim Tab Settings for Takeoff table, page
NC-5.

Ground Spoiler System Check OM 2A-27-70
The ground spoiler system is monitored by a warning circuit that will
detect certain in-flight and on-ground malfunctions within the ground
spoiler system, prompting the following annunciations:
• A red GND SPOILER warning message will be displayed on CAS
and, if installed, the SWLP, should a failure occur within the
ground spoiler system either while airborne or on the ground.
• A red NO GND SPOILERS warning light, located adjacent to the
