| 摘要： | An increase in the required pathway width from aircraft center aisles to Type III overwing exits is being weighed by the FAA. To augment the analysis, an examination of seat/exit configuration effects on simulated emergency egress was conducted in the CAMI Evacuation Research Facility. METHODS. Four subject groups traversed four different seat/exit configurations in a counter-balanced, repeated-measures design. Pathway width was modified by altering seat pitch. RESULTS. In single-exit trials the fastest times and highest flow-rates occurred with a 20 pathway between triple seats or a 10 pathway between double seats. Double exits produced 36%shorter egress times (p<.007), although flow-rates declined 11%and exit Plug removal times increased 32%, compared to single exits. Efficient egress requires optimization of the space around the exit. Generally, wider pathways and fewer obstructions enhance this process; however; when available space exceeds individual passenger needs, conflicts may be produced which inhibit egress.
