Normal procedures and recommended speeds
4.5.1 Takeoff and climbing
Aerotow
Approved ropes made of synthetic and natural fibers with length
from 30 to 60 m (98 - 196ft.) may be used for aerotowing.
If a nose hook is installed, we recommend to use this one.
Nevertheless the C.G. hook is approved for aerotow, too.
When commencing the take-off run, use wheel brake slightly to
prevent rolling over tow rope.
Before takeoff adjust the trim depending on the cockpit load. The
trim should be in neutral position if the sailplane C.G. ranges from
forward to medium position. If the C.G. ranges from medium to rear
position, then trim "nose heavy".
After lift-off and when a speed of about 75-80 km/h (40-43KIAS, 47-
50 mph) is reached (this speed is increasing up to 15 % with the
water ballast), adjust the trim to decrease elevator control forces.
Normal towing speed .. 100-120 km/h 54-65 KIAS 62-75 mph
Max. aerotowing speed .......150 km/h
81 KIAS
93 mph
The main landing gear can be retracted during tow.
Should the sailplane be unintentionally displaced laterally, it should
be cautiously but immediately steered back to normal aerotow
position. Should the sailplane be displaced vertically too high, with
a danger of over-flying the tow aircraft, the air brakes should be
open.
Rope release:
Pull the release knob several times to be sure, that the rope was
released.
