FAA to test whether packed planes affect evacuation time

- By David Koenig

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 first-of-its-kind test to determine if 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 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 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.

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

Airlines “are cramming in more and more and more seats, closer and closer together. People are getting bigger,” House Transporta­tion Committee Chairman Peter DeFazio, D-Ore., told the FAA’s deputy administra­tor at a hearing last month.

The distance from any point on a seat — say, the front of the armrest — and the same spot on the seat in the next row is called pitch, and pitch has been shrinking. A few years ago, the standard was around 34 inches. Today in the economy cabin of U.S. airlines it is more often around 30 or 31 inches, and even tighter on some, including Spirit Airlines.

Planes are also more crowded. The average flight now is about 85% full, and during peak hours every seat is taken.

Consider also that more passengers carry bags on board, and hundreds of thousands of them bring an emotional-support animal, too, and it stands to reason that it will take longer to get everybody out during an emergency.

Until last year, the FAA resisted calls to set minimum seat and row standards, saying those are matters of passenger comfort, not safety, and it’s a safety regulator.
