Aircraft Evacuation Times Exceed 90-Second Requirement, Study Finds
A new study published in AIP Advances has raised concerns about the Federal Aviation Administration's (FAA) 90-second evacuation requirement for aircraft passengers. The study, which simulated various emergency scenarios, found that evacuation times often exceed the required 90 seconds, particularly for elderly passengers who may need more time and assistance. This is a significant issue, given the increasing number of elderly travelers on commercial flights.
Researchers have been studying the optimization of aircraft evacuation for years. In 2011, Jason Steffen, a physicist at the University of Nevada, Las Vegas, developed an efficient boarding method known as the "Steffen method." This method involves having passengers board in a series of waves, which has been shown to be almost twice as fast as traditional boarding methods. The key to this approach is parallelism, where multiple passengers can board at the same time.
The study's findings have implications for the design of aircraft seating and evacuation procedures. By allowing slower passengers to board first, airlines may be able to reduce evacuation times and improve safety. This approach also highlights the importance of considering the needs of elderly and disabled passengers in aircraft design.
When Jason Steffen says that parallelism is key to efficient boarding, that means airlines should prioritize designs that allow multiple passengers to board at the same time. This could involve rethinking traditional seating configurations and evacuation procedures to prioritize the needs of slower passengers. By doing so, airlines can improve safety and reduce the risk of evacuation delays, which is particularly important for elderly and disabled passengers who may need more time to board.
