Expanded Use of Analytic Modeling in Cabin Safety Applications

This research will explore the potential applications for numerical modeling in various cabin safety areas (including evacuation and ditching), and establish criteria for validation, as well as credibility of models for use in certification. Cabin safety requirements often result in a destructive test (e.g., seat dynamic testing), testing involving risk to persons (e.g., evacuation testing) or testing that has limited statistical basis (e.g., escape slide testing.) In all of these cases the use of numerical modeling would be very useful, provided the models were sufficiently credible and the criteria for their use was well understood. Historically, the FAA has been very cautious about accepting numerical models in these areas, because of the lack of good validation criteria, and because there was very limited experience within the FAA on the use of modeling.
