Previous work has presented both a theoretical foundation for designingterrain park jumps that control landing impact and computer software toaccomplish this task. US ski resorts have been reluctant to adopt this moreengineered approach to jump design, in part due to questions of feasibility.The present study demonstrates this feasibility. It describes the design,construction, measurement and experimental testing of such a jump. It improveson previous efforts with more complete instrumentation, a larger range of jumpdistances, and a new method for combining jumper- and board-mountedaccelerometer data to estimate equivalent fall height, a measure of impactseverity. It unequivocally demonstrates the efficacy of the engineering designapproach, namely that it is possible and practical to design and build freestyle terrain park jumps with landing surface shapes that control for landingimpact as predicted by the theory.
