NOTE:
With the CG in the aft position the launch should be
commenced with the trim in the full forward setting.
Adjust the trim during the tow as required.
For an assisted aerotow, the procedure is similar to the one used for
conventional aerotows. Aerotowing behind towplanes with less power,
e.g. ultra light aircraft or touring motorgliders or taking off from short
runways may be conducted with the electric power plant running. The
take-off distance is significantly reduced if the motor is extended and
running at a, maximum allowed, power of 20 kW during the aerotow.
Once the ground run starts, the glider pilot can start to apply power.
Only level tow position is permitted, with the rope length equal to the
conventional aerotow rope lengths. The speed and flap range is equal
to

with the difference that the
minimum safe speed is 125 km/h (67.5 kts) and the maximum speed is
limited to 150 km/h (81 kts).
Should at any time during the assisted tow a significant amount of slack
in the towrope occur, it is advised to release immediately and continue
the climb as a normal self-launch. Once the sailplane is clear of the
rope, the power can be increased to more appropriate settings,
depending on the temperature of the components.
NOTE:
This take-off procedure is only permitted if the
conditions are such that a tow with pylon retracted can
be executed safely.
To ensure good communication with the tow pilot the use of a headset
is highly recommended. The power plant must be retracted during
cross country aero tows with speeds exceeding V

Procedure:
1. Complete normal pre-take off checks
2. Extend motor and test motor operation while applying wheel
brake
3. Initiate the aerotow take-off without power
