Winch-launching
WARNING
NEVER use the nose release mechanism (if installed) for winch-
launching!
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".
When commencing the take-off run, use wheel brake slightly to
prevent rolling over tow rope.
This sailplane shows normal behavior during winch-launching and
even with rear C.G. positions has only a minor tendency to enter
into a steep climb after take-off. Depending on the trim-setting, a
correction with the elevator may be necessary to prevent a steep
climb in the early take-off phase.
After a safety height of approx. 50m (150ft) is reached, the
sailplane can be brought into a steeper climb by more back
pressure on the control column. If too much back pressure is
applied and proposing occurs (elevator stall), release some of the
back pressure.
Avoid rapid lift-off maneuvers or low towing speeds.
The high wing loading of this sailplane requires the pilot to abort the
take-off and release, if the towing speed drops below 95 km/h, 51
KIAS.
WARNING
The low performance winches with limited engine RPM and other
limitations, as well as the takeoff at the tail wind conditions, calm
air, filled water tanks etc., require special attention before take-
off, to ensure that the winch is providing enough power in reserve
to maintain the safe towing speeds.
