Occupant Weight Assumptions Have Fallen Behind The Population
Dynamic test standards were written against occupant weight distributions that no longer describe the travelling public, and several authorities have moved that observation from discussion into active rulemaking. Widening the required range obliges requalification of seat and restraint combinations tested against narrower assumptions, which is dynamic testing rather than paperwork. Suppliers who anticipated the change and tested across a broader range hold evidence competitors will have to generate at roughly USD 340,000 per configuration. Population data moved faster than the standards written against it, which is nobody's fault and everybody's problem.
Market Impact: Costs 3.1 times conventional seats
