Abstract

The evacuation certification trial is an aviation benchmark which requires that all the passengers must safely evacuate from the aircraft within 90 seconds through 50% of the available exits. Typically a single exit from each pair of exits is selected resulting in all available exits being located along one side of the aircraft. In this study, the influences of exit availability in post-crash aircraft fires on passengers' survivability are investigated using a narrow body aircraft, which satisfies the certification requirement. Two exit configurations are investigated: one complying with the typical certification trial configuration and the other one being an exit configuration commonly occuring in real accidents. The work is carried out using the fire and evacuation engineering tools, SMARTFIRE and airEXODUS. Uner a post-crash cabin fire situation, the certification trial exit configuration produces a longer time to flashover, a shorter evacuation time and as a result a significantly smaller number of fatalities and severe injuries than the other investigated exit configuration. As a safety indicator of aircraft evacuation performance, the exit configuration in the certification trial is demonstrated to be less challenging and less representative of actual accident situations and so is considered inappropriate as a measure and demonstration of safety.
