4.5 Normal procedures and recommended speeds

4.5.1

Launch

Due to the towhook position being in the middle of the fuselage and the
excellent effectiveness of the ailerons and rudder, the possibility of wing
dropping or ground loops, even on a slowly accelerating aerotow is reduced.
Take-off with strong crosswind is possible.
4.5.1.1 Aerotow
a) Aerotow is permitted only using the nose tow release. Set trim to neutral for
aerotow.
b) Version with nose wheel: Pull the stick until the nose wheel lifts off from the
ground. Then control the aeroplane so, that nose wheel and tail wheel don't
touch the ground.
Version without nose wheel: Keep the elevator in neutral 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 185 km/h (98 kts.).
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!
