7.3.7. Wing
flaps
The flaps are driven by a geared electric motor and are activated via the flap control
in the lower section of the instrument panel. The desired flap setting is selected with
a lever switch. The position indicator will flash as long as the flaps are moving to the
desired setting. Once the desired setting has been reached, the position will be
constantly illuminated. The flaps may be set at any of the following positions:
- 6°, +0°, +15°, +30°, +35°.
The flap motor is integrated into the mixer behind the main bulkhead in the aircraft
baggage compartment. As It acts on the controls mixer, the flaps are activated via
push rods. Both flaps are directly attached to a torque tube in the fuselage, thus
ensuring that they are always deflected symmetrically.
Warning:
An individual maximum airspeed is defined for each wing flap setting.
The pilot must observe these to ensure that the aircraft and the flight
controls are not over-stressed.
The flap servo has an internal load-limiting device which prevents the extension of
the flaps at too high airspeeds without causing sustainable damage to the structure.
Should the indicator blink constantly when extending the flaps, airspeed should be
reduced. If the flaps then extend, the internal load-limiting device was in operation. If
extension speed is below the maximum speed for flap extension as given in the
handbook, the flap system may be out of adjustment. The nearest Flight Design
service station should be contacted.
The flap control dual circuit breaker is to be found directly adjacent to the flap
controls. It will pop if the flap servo is continuously over-loaded. As it is a thermal
circuit breaker, it can take some time before it can be pushed back in. We
emphasize once again that the CTLS can be flown and landed safely in any flap
position. Refer to Chapter 3 - Emergency Procedures.
