The FAA HIII-50M is a Hybrid III 50th percentile male automotive crash test dummy modified for Federal Aviation mandated crashworthiness safety testing for general and transport category aircraft and general and transport category rotorcraft.
Aircraft crashworthiness safety testing was originally done with Hybrid II 50th percentile dummies. The FAA HIII-50M dummy was developed by a Humanetics predecessor Denton ATD. As compared to the Hybrid II dummy, it incorporates the Hybrid III Head, Neck, rib cage most upper torso components, arms and legs. The chest flesh, lower torso and upper legs are modified to allow abdominal compression and lumbar flexion tests used with the Hybrid II to insure similar torso bending over the lap belt and measurement of lumbar compressive force required by the aircraft safety standard.
