In Need Of Some Restraint

One of the side benefits of having some spare airframes, a test facility and a bunch of motivated engineers is the other kinds of testing you can do. According to Chad Stimson, NASAs project manager for the ongoing ELT testing, other data also is being collected, mostly as a supplement to earlier studies.

Key Takeaways:

NASA is utilizing ongoing ELT testing to collect supplemental data, including observing the effects of crash impacts on restrained versus unrestrained dummies.
During a vertical drop test of a Cessna 172, an unbelted dummy was shown to impact the control yoke severely, while a dummy restrained by a shoulder harness barely moved.
The crash test results strongly emphasize the critical importance of installing and using shoulder harnesses in aircraft for occupant safety.
