Aircraft emergencies requiring evacuation present unique safety challenges to both crew and passengers due to theconfined space and the speed at which fire, extreme heatand smoke propagate. In thisscenario, where a one or two second delay can literally determine survivability, rapid evacuation is paramount. Although evacuation capability is demonstrated through requiredand controlleddrillsfor aircraft certification, during a real emergencyhuman factorsaffect passenger decision making, in some cases resulting in the decisionto retrieve personal items during actual emergency evacuations. This may pose a significant threat to post-accident survivability. This research evaluates evacuation decision making and the associated impact on passenger exit flow, during emergency evacuation scenarios. This paper provides an update on a controlled field study using a functional CRJ-100 50-seataircraftto explorethe contributingfactors affecting passengerthreat awareness and decision making during aircraft evacuations.
