FAA to test whether packed planes affect evacuation time

Researchers will compare tests to see if smaller seats or tighter rows make any difference

OKLAHOMA CITY — The size of your seat and how much legroom you’ll get on a future flight could be decided by 720 Oklahomans taking part in a firstof-its-kind test to determine if jam-packed planes slow emergency evacuations.

Frequent flyers on U.S. airlines are all too aware that cramped economy cabins are detrimental to comfort. But federal officials who write airline safety rules have never tested whether smaller seats or tightly packed rows have any effect on evacuation time.

“It is a big pet peeve of flyers, but that doesn’t necessarily mean that there is a safety issue,” said Stacey Zinke-McKee, a medical-research official at the Federal Aviation Administration facility in Oklahoma City where the tests are being conducted.

Beginning next month, FAA researchers will recruit people from churches, universities and online to come up with a test group similar to the overall U.S. population. Sixty at a time, they will be seated in a simulator laid out like a Boeing 737 or an Airbus

A320, planes commonly used on domestic flights.

Flight attendants will tell them to get out of the simulator — money will be paid to the first ones off to mimic the sense of panic that occurs in an emergency. Then the seats and rows will be reconfigured, and they will run the tests again — four times with each group of 60 volunteers.

The researchers will compare tests to see if smaller seats or tighter rows make any difference. A dramatic difference would presumably be reason for FAA to set more generous minimum standards for the airlines to follow. An FAA rulemaking panel will use that data to help set seating standards for airlines, with a decision possible by late next year.

The average American adult is about 10 pounds heavier than just two decades ago, according to government figures, and airlines are squeezing more passengers into the economy cabin to make more room for high-paying customers in business class. That means tighter rows in the back of the plane.

Congress last year ordered the FAA to set minimums for seat sizes and the distance between rows.
