CONTROLWHEELS~TCHES
The left grip of the pilot's control wheel will normally contain the
following autopilot switches:
Manual Electric Trim
Trim Interrupt/ AlP Disconnect Switch
Control Wheel Steering (CWS)
If the optional co-pilot switch arrangement is installed, the same three
switches with the same functions will be installed in the right grip of the
co-pilot's control wheel.
ELECTRIC TRIM SYSTEM
The S-TEC Electric Trim System is designed to accept any single failure,
either mechanical or electrical, without uncontrolled operation resulting
during operations in the Manual Electric Trim Mode. During autotrim
mode the system is designed to limit the effect of any failure causing trim
operation. In order to assure proper operation of these safeguards, it is
necessary to conduct a simple pre-flight test of the system. Following is
a brief description and a pre-flight
~est
procedure for the trim system.
