FLIGHT CONTROLS

The ailerons and elevator are actuated via push rods. The rudder is controlled using control
cables. The flaps have three positions, CRUISE, T/O (take-off), LDG (landing), and are
electrically operated. The switch is located on the instrument panel. The flap control circuit
breaker can be manually 'tripped' to disable the flap system. Elevator forces may be balanced
using the electric trim system.

7.3.1. Trim System

The Rocker switch is located on center console behind the throttle quadrant. The digital trim
indicator is located in the upper instrument panel.
The switch controls an electrical actuator beside the vertical push rod in the vertical stabilizer.
The actuator applies a load to compression springs on the elevator pushrod. The trim circuit
breaker is located in the circuit breaker panel and can be tripped manually to disable the
system.
switch forward = nose down

7.3.2. Flaps

The flaps are driven by an electric motor. The flaps are controlled by a three position flap
operating switch on the instrument panel. The three positions of the switch correspond to the
position of the flaps. The top position of the switch is used during cruise flight. When the switch
is moved to a different position, the flaps move until the selected position is reached. The cruise
(fully retracted) and landing (fully extended) positions are equipped with position switches to
prevent over-traveling.
The electric flap actuator is protected by a circuit breaker (5 Amp), located on the right side of
the instrument panel, which can be manually tripped to disable the system.
