3  Extended approaches
[German version]

An extended approach should certainly take account of the movement of cargo units associated with direct securing, without which a deformation of the securing devices and thus the necessary generation of force is not possible. If it is possible in this way to define "acceptable" cargo movements, identical movements could also be permitted for arrangements with frictional securing (tie-down lashings). This could in turn lead to a re-assessment of this securing method, possibly with more favorable results.
