Total length measured from the underside of the glider to the inner edge of the risers with a tenstion of 50 [N]. Measured values do not include the uncertainty/The uncertainty stated is the expanded uncertainty obtained by multiplying the standard uncertainty  

by the coverage factor k = 2. The  measured values lies within the assigned range of values with a probability of 95%.
