MDW To Get Arrestor Beds...

Thu Apr 06, 2006 1:13 am

Look like MDW will be getting EMAS installations in the near future. These are the special crushable concrete panels that contain an overrunning aircraft and keep it from going off the end of the runway.

If you're interested in how it all works, check out:

The Saab 340 and MD-11 pictured were snagged by the EMAS installation on the rollout end of 04R at JFK. This was the first EMAS installation in the country, and in addition to the Saab 340 and MD-11, it's also snagged a 747.

Some photos of existing EMAS installations across the US.

There's also a video (just under 9 minutes long) that shows how it all works, including footage of a FAA 727-100 being snagged during testing.

Isn't this going to, by default, make the "usable" portion of the runway even smaller? Or am I totally misunderstanding that.

Also, how the heck does a Saab 340 overrun at JFK? Holy crap.

It passes the threshold at a speed higher than 0..  duck   Smile Just teasing.
It only takes five years to go from rumor to standard operating procedure.

The video had some good information in it as far as FAA rules/standards go...

I think the video mentioned that the Saab 340 went off the end at 70 knots...

If he was still going 70 knots, just how far down the runway did he touch down ?

He must've missed the "piano keys" literally by almost 2 miles, provided conditions were clear and nothing impeded braking ...

I have no idea of any of the particulars that led to his going off the end at 70 kts. I was just repeating what was mentioned in the video.

No my home city of Chicago is planning to expand the airport by acquiring land currently occupied by homes and businesses. I guess eminent domain is involved in this. Chicago Tribune has a nice story with a graphic (registration/bugmenot required)

Quote:
The city estimated it would cost $200 million to $300 million to acquire the property off the airport needed to build runway safety areas. The city said it would require condemning 350 to 700 residential buildings and 80 to 130 commercial buildings.

I am not sure if this will happen either easily or soon.

They are not going to expand the runways or airport. They only stated what it would cost if they were going to. They followed your quote with the following:

"The aircraft-arresting system was considered the next-best alternative."

The city will not expand the runways at MDW. Expanding the runways is an alternative to the arrestor beds. But expanding the runways would cost more.

The areas where the arrestor beds are goin to be, will not eat up usable runway space. I think the arrestor beds will be placed behind those yellow lines at the end of the runways. The area that is no accessible to airplanes.

Here is a picture to give you an idea where the arrestor beds will be located, view in the large image

It should be interesting to see how they re-locate the ILS localizer antennas...

They have a stopway, they don't need one. A declared distance is used on the runway length and the stopway adds the protection that would be an EMAS/RSA.
