Normal procedures and recommended speeds

4.5.1

Tow launch

Due to the towhook position in the middle of the fuselage (underside) and
due to the excellent effectiveness of the ailerons and rudder, the
possibility of wing dropping or ground loops, even on a slow starting
aerotow is reduced. Take-off with strong crosswind is possible.

Aerotow

a) If only a C.G. release is installed, then the aerotow is to be executed

with this release.
Set the trim full nose down for aerotow.

b)

Caution:

If an additional tow release for aerotow is installed, only this release
should be used for aerotow. Adjust the trim for aerotow to fully nose
down position.

c) General: Set the wing flaps to +13°.

Hold the stick in the forward position.
Don't try to lift off before you reach an airspeed of 80 km/h (43 kts.)
(without ballast).
On a rough airfield hold the control stick tight. The undercarriage can
be retracted at safety height during the tow.

Normal towing speed is 120-130 km/h (65-70 kts.).

For a cross country tow the speed can be as high as 190 km/h (103 kts.),
the flaps should be at a negative setting. (see sect. 4.5.2).

Warning:

Aerotow with high take off weight requires a powerful tow

plane.

Many tow planes are not certified to tow gliders with high take off
weights. Reduce the take off weight if necessary!
