Chicago midway airport is set to install an Engineered Materials Arrester System (EMAS) to help guard against potentially dangerous runway overruns.
The news follows the death of a six year old child at the airport in December 2005, when a Southwest Airlines plane from Baltimore careered off the runway and crashed into two cars.
The move to install the EMAS has been widely welcomed.

Bloody hell! Only flown in there once in a 757-2. Can't remember any stop dist probs, what is the reason for Midway being prone to over runs? Forgive my lack of local understanding.

Maybe before rushing in to a knee-jerk reaction to what was actually a minor accident in the general scale of things, but which has made and continues to make good revenue for lawyers, they would like to look at why London City, which has a far worse "tight runway" situation, recently removed their arrestor systems at the end of the runway at quite some expense, to replace them with just plain concrete with a high friction coefficient finish.

All I can say is if you have never landed a large airplane, such as a Boeing 727 in my case, on a regular basis at Midway you do not understand how important installing this system will be for safety and sanity.

On a nice day everybody sweats landings at Midway in anything larger than a small Citation.

I doubt that London City gets heavy snow / slush anywhere near as frequently as Midway. The one-square-mile airport, located 8 miles southwest of downtown Chicago, was built in 1923 and is hemmed in by dense neighborhoods. Midway has about 900 operations a day and that may increase as Southwest plans to add quite a few more flights. "Midway has surpassed Baltimore-Washington and tied Phoenix as Southwest's No. 2 airport with 196 daily departures. According to a recent Citigroup report, it is expected to overtake Las Vegas to become the Dallas-based carrier's largest airport by 2007."

If you don't know why this is a good thing at MDW, then you have probably never flown in there in a Jet transport.
Very short runways and if you overrun the runway you are in someones house.

If everybody: always flew perfect approaches all systems always worked perfectly without interlocks ever getting in the way the runways were always perfectly swabbed nobody ever picked up a tailwind component or got caught out by windshearEMAS would be a waste of money.

In the real world where people make mistakes and mechanical things don't always work as expected, overruns happen and will continue to happen.

Midway runway update planned to slow jets

April 6, 2006

BY: MONIFA THOMAS Transportation Reporter

By the end of the year, the City of Chicago could begin building beds of crushable concrete on runways at Midway Airport to halt planes that have overshot their landings, city aviation officials said Wednesday.

Earlier this week, the city submitted a proposal to the Federal Aviation Administration to install the concrete beds at the end of four Midway runways. Four months ago, 6-year-old Joshua Woods was killed when a Southwest jet slid off a slick runway at the airport and crushed his family's car.

The beds would be made of lightweight concrete bricks designed to collapse under the weight of an aircraft, safely slowing or stopping it within a few hundred feet. The FAA has already approved similar aircraft-arresting systems at 14 airports.

FAA approval sought

The city's plan is a departure from statements Mayor Daley made days after the fatal Dec. 8 crash. Then, Daley said major changes at Midway weren't needed to improve safety.

But as early as last fall, the city was reviewing ways to create a better safety zone at Midway ahead of new federal regulations, said Erin O'Donnell, managing deputy aviation commissioner at Midway.

Midway is one of 300 commercial airports across the country that do not have a 1,000-foot clearance zone at the end of the runway, which the FAA considers a margin of safety. Those airports have until 2015 to extend their safety protection zones or build other safeguards, the FAA says.

Other options at Midway would have been to shorten the runways to provide a larger buffer zone or acquire more land to build one. But the concrete beds were the only practical alternative that would not involve cutting airport operations or bulldozing hundreds of homes and businesses, O'Donnell said.

Pending FAA approval, the city could begin installing the buffers by the end of the year. The city estimates a cost of up to $40 million.

FAA spokesman Tony Molinaro called the city's proposal "a good first step," but more analysis needs to be done.

Of particular concern for the FAA is the fact a standard emergency arresting system is about 600 feet long, while the ones proposed for Midway range between 200 and 300 feet, Molinaro said. "We want to see some detailed analysis about what kind of planes it can truly stop and at what speeds, to see if it's even viable.".

Does anyone know why City removed their EMAS?
They had an incident about 10 years ago to a 146 in which, to cut a long story short, AAIB concluded that if it had been raining they would have gone off the end. That's probably why they got the EMAS, but why on earth take it out? There should be more of these around, not fewer.

I think this article is misleading it should say Southwest Airplanes are prone to overruns, not Midway airport. :p

Or in the case of Burbank airport someones gas station. Well not anymore since it was torn down.:p
