7.3. FLIGHT
CONTROLS
The ailerons and elevator are actuated via push rods, and the rudder is controlled using control cables.
The flaps have three positions (up [UP], take-off [T/O], and landing [LDG]) and are electrically operated.
The switch is located on the instrument panel. In addition the flap control circuit is provided with a
manually triggerable circuit breaker.
Elevator forces may be balanced using the electric trim system.
7.3.1. Trim System
The Rocker switch is located on center console behind engine control unit. The digital trim indicator is
located in the middle of the instrument panel.
The switch controls an electrical actuator beside the vertical push rod in the vertical stabilizer. The
actuator applies via compression springs a load on the elevator controls. Its circuit breaker is located in
the circuit breaker panel and can also be triggered manually.
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, where
the top position of the switch is used during cruise flight. When the switch is moved to a different position,
the flaps move automatically until the selected position is reached. The up (fully retracted) and landing
(fully extended) positions are additionally equipped with a limit switch to prevent overtraveling.
The electric flap actuator is protected by an automatic circuit breaker (3.5 A), located in the circuit breaker
panel, which can also be triggered manually.
7.3.3. Flap Position Indicator
The current flap position is indicated by three control lights beside the flap operating switch.

When two lights are illuminated at the same time, the flaps are between these two positions. This is the
case while the flaps are in motion.
