A new study suggests a novel approach to improving aircraft evacuation times: strategically seating elderly passengers. While air travel is statistically safe, real-world emergencies present challenges not fully reflected in current FAA 90-second evacuation standards.
Research simulating an Airbus A320 emergency, where over-wing exits are unusable, found that distributing elderly passengers evenly near exits, rather than concentrating them, could optimize evacuation. Simulations involving up to 180 passengers indicated that while a flight with 20% elderly passengers seated near exits was fastest at 141 seconds, simply having a high proportion of elderly passengers, even near exits, led to longer evacuation times (up to 218.5 seconds).
As the global population ages, with the median age projected to rise, updated evacuation guidelines are becoming essential. Researchers hope these findings will prompt airlines to consider more strategic seating arrangements to enhance passenger safety during critical incidents.
