BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual page 392

GENERAL
Primary flight control surfaces are positioned
by hydraulic power control units (PCU's).
Each PCU is controlled by pilot, copilot, or
AFCS inputs transmitted through mechanical
linkages. Each surface is protected from wind
gust damage while on the ground by the damp-
ing effect of the PCU.
Artificial feel units in each control system
simulate aerodynamic forces and provide nec-
essary load feel to the pilot.
Self-contained hydraulic dampers prevent
aileron and elevator flutter.
The flaps are actuated by two electric motors
in the flap power drive unit (PDU). Motor out-
put mechanically drives all flap segments.

A proportional flight spoiler on the upper sur-
face of each wing, forward of the outboard
flaps, provides lift modulation. Hydraulic ac-
tuation of the spoilers is initiated by inputs
f r o m a c o n t r o l l ev e r i n t h e c o c k p i t .
Hydraulically powered ground spoilers, for-
ward of the inboard flaps, provide lift dump
during the landing roll. The ground spoilers
are operable only when the weight on wheels
(WOW) system or wheel spinup information
detects an on-ground condition.
Visual warning of an impending stall, stick
shaking, and continuous ignition on both en-
gines is provided by the stall protection sys-
tem. Extreme angles of attack result in stick
pushing and the sounding of an aural warning.
Flight control surfaces are shown in Figure
15-1.
