Abstract:This report is the final deliverable of a contracted modelling effort requested in support of FAA efforts to address recommendations to investigate the effects of luggage retrieval on emergency evacuation of transport airplanes. The impact of passengers retrieving cabin luggage on evacuation performance was explored using state-of-the-art evacuation computer simulation. The analysis focused on a single-aisle, narrow-body aircraft configuration consisting of 185 passengers and crew in a cabin layout typical of the widely used B737/A320 aircraft. The airEXODUS agent-based aircraft evacuation modelling tool was enhanced to represent passenger luggage retrieval behavior and was used to quantify evacuation performance, with and without passengers retrieving luggage. Furthermore, the exit scenario studied in this analysis consisted of the front pair of Type-C exits and the left pair of overwing Type-III exits, an exit combination often occurring in fatal accidents — and representing 50% of the normally available exits. Four luggage retrieval scenarios were investigated involving 0%, 25%, 50%, and 75% of passengers attempting to retrieve luggage, with each scenario repeated 1000 times and luggage retrievers randomly distributed throughout the aircraft for each repeat simulation. This report explores key takeaways and implications of the findings of the modelling effort.
