ADDITION TO THE SAFETY BULLETIN #6
CONCERNING PLATFORM TOWING ONLY.
We have done ground tests with the rope attachment at the nose junction
to the front bolt between the keel tube and the bottom nose plate(as it
has been suggested by Martin Henry in OZ
Report # 213). With the slot made in the right place of the nose cone
it was impossible to get the rope or the nose cone to interfere with the
safety spring, the nose wire hook or the front wires.
To determine the correct location for the slot in the nose cone we recommend
to rig the glider on the tow system (without the nose cone in place) , then
transfer the nose release line angle on to the nose cone. The 2 inch (50
millimeters) slot will allow for a reasonable amount of angle of attack
variation (see Martin Henry's suggestion in the OZ
Report # 213).
As a result of these tests we have reached conclusion that it is possible
to use the abovementioned method of the rope attachment for the gliders
used for platform towing without changing the front wires with the wires
For those pilots who are still willing to perform the modification of their
gliders with the retrofit kit (see Safety Bulletin N 6)
for the platform tow Aeros will provide the parts for modification as an
