4.5.1 Methods of launching
Aerotow
(Only permissible with nose tow release in place)
Maximum permitted towing speed:
V
T
= 180 km/h (97 kt, 112 mph)
For aerotow only the nose tow release must be used. hemp and nylon ropes of
between 30 and 40 m length (98-131 ft) were tested.
Prior to take-off – to be commenced with flap setting "0" – set the elevator trim as
follows:
•
Rearward c/g positions : Knob forward to first third of its travel
•
other c/g positions:
Knob to the middle of its travel
As the tow rope tightens, apply the wheel brake gently (by actuating the
stick-mounted lever) to prevent the sailplane from overrunning the rope.
In crosswind conditions the aileron control should be held towards the downwind
wing, i.e. in winds from the left the stick should be displaced to the right.
This is to counteract the lift increase on the right wing generated by the tug's prop
wake, which the crosswind forces to drift to the right.
For intermediate to forward c/g positions the elevator should be neutral for the
ground run; in the case of rearward c/g positions it is recommended that down
elevator is applied until the tail lifts.
