Tow rope and predetermined breaking point:
Only ropes, which correspond to the aviation standards, can be used, DIN
or factory standards, if these standards (specifications) contain sufficient
information and ensure the delivery of consistent quality. The rope
connection must be protected against abrasion by a suitable coating.
When using the tow rope without a predetermined breaking point the true
ultimate load of the tow rope must not exceed 300 daN. In the case of tow
ropes with a higher ultimate load, a predetermined weak link must be
installed for the protection of the aircraft and the glider.
Length of the tow rope: .......................................... 131 - 197 ft (40 - 60 m)
Max. nominal breaking strength
of the weak link: .............................................................. 660 lbs (300 daN)
Joining ring pair on the tow rope according to LN 65091
