Test Button
Depressing the test button initiates a test of the
KFC

circuitry, including operation of various
modes and of the trim. The test must be
performed after power is applied and before the
autopilot can be engaged, but the flight director
can be used without the test being performed.
Vertical Trim
This rocker switch allows you to make small
corrections in selected altitude while in altitude
hold, or adjust pitch attitude at a rate of
approximately
.9
degrees per second when not
in altitude hold.
Control Wheel
Steering

This button mounted on the control wheel allows
you to maneuver the aircraft in pitch and roll
without disengaging the autopilot. After the CWS
button is released, the autopilot resumes control
of the aircraft.
