Replacement of Cushions in Energy Absorbing Seats – EA Seat performance

This project will evaluate potential methods for replacement of worn seat cushions used in energy absorbing seats. Streamlined approaches to the replacement of worn cushions in aircraft seats have been requested by the aviation industry. The Federal Aviation Administration (FAA) developed a method for seats that do not require energy absorption (Part 25 and Part 23 passenger) based on rigid seat performance as a reference point. This method may not be valid for energy absorbing seats used in Part 27/29 and Part 23 pilot seats. As part of an effort to evaluate streamlined approaches, this project will characterize the seat and occupant response of typical energy absorbing seats.
