Monday Edition: Airports Need Runway Space or EMAS
There is a follow-up to the
Chicago Midway Airport
airplane accident waiting for you locally. As I fly into
airports all over the country, I am struck by how many of them are
surrounded by neighborhoods, hotels and business parks. Many of these
airports were built in the rural suburbs. But now the cities have
closed in. The Associated Press reported that at least 300 airports do
not have the recommended 1,000-foot space at the end of a runway,
a precaution put in place should an airplane overrun a landing or abort
a takeoff, and there is not often room to build them. The
Federal Aviation Administration said in August:
Since
many airports were built before the 1,000-foot extension was adopted
some 20 years ago, the area beyond the end of the runway is where many
airports cannot achieve the full standard [Runway Safety Area]. This is due to obstacles
such as bodies of water, highways, railroads and populated areas or
severe drop-off of terrain.
The AP says:
Nearly 300 U.S. commercial airports, including Chicago's Midway, lack the 1,000-foot margin at the end of the runway that the federal government considers adequate for safety.
Many are older
airports squeezed next to dense city neighborhoods, bodies of water or
steep drop-offs that don't have the available space.
Runway overruns can be extremely dangerous. In June 1999, an American Airlines jetliner slid past the end of the runway in Little Rock, Ark.,
killing 11 passengers and injuring 86. And it was only the remarkable
speed of the passengers' evacuation -- less than two minutes -- that
prevented serious injury or death when an Air France Airbus skidded off
the runway in Toronto and burst into flames in August.
The Federal Aviation
Administration in the 1990s began researching solutions to the runway
barrier space problem and found that a certain light, crushable
concrete will cause an airplane to decelerate quickly. The soft
concrete bed, called EMAS for Engineered Material Arresting Systems,
extends about 600 feet from the runway's end.
The FAA says
14 airports around the country have such EMAS systems. Four more are
working on them. Hundreds more need them to comply with FAA
recommendations.
Those completed systems, the number of systems installed and the dates they were completed are below, as reported by the FAA:

This is a newsletter for airport executives, called "Centerlines." [PDF] It is published by a trade group, Airports Council International -- North America. Go to Page 28 for a quick story on how these EMAS systems work.
The AP explains that
these EMAS systems could be a solution to landlocked airports that
cannot get more space to build new runways:
Planes that overrun a
runway sink into the concrete, like a bit truck sinks into gravel on a
runaway truck ramp on highways. [...]
In New York, the
beds have stopped three dangerous overruns three times since May 1999
at John F. Kennedy International Airport, including a Boeing 747 in
January, according to the FAA.
New Jersey Sen. Frank Lautenberg sponsored an amendment to a House appropriations bill that would ensure that airports improve their RSAs. Last February, a corporate plane carrying 11 people ran off the end of
his home state's Teterboro Airport runway during an aborted takeoff, sped across a busy road
and hit a warehouse. Twenty people were injured.
This is a very thorough May 2003 National Transportation Safety Board briefing on the issue [PDF]. There is no doubt, the FAA said, that the EMAS systems have
saved lives and could save more lives. The FAA says airports that have
neither EMAS systems nor the 1,000-foot ramps at the end of
runways should get on with installing the systems right away:
The safety benefit of
EMAS was demonstrated on May 8, 1999, when American Eagle flight 4925,
a Saab 340B, overran the departure end of runway 4R at John F. Kennedy International
Airport
(JFK),
Jamaica,
N.Y. The airplane traveled approximately 248 feet across an EMAS before it came to a stop. Of
the 30 people onboard the airplane, 29 were not injured and one
sustained a serious injury during the evacuation. A safety board
performance study estimated that, without the EMAS, the airplane would
have entered
Thurston Basin, a waterway approximately 600 feet beyond the end of the runway.
The board is also aware of several overrun accidents in which major damage to the aircraft and injuries
to passengers might have been prevented or mitigated if an EMAS had
been installed at the end of the runway where the accident occurred.
A
recent example of such an accident occurred on March 21, 2000, in which
a Saab 340B twin turboprop airplane, operating as American Eagle flight
3789, sustained substantial damage upon impact with a drainage ditch
following a runway overrun during the landing roll on runway 01 at the Killeen Municipal Airport, Killeen, Texas.
The
airplane came to rest in a ditch 150 feet beyond the departure end of
runway 01 and aligned with the right edge of the 100-foot-wide runway. The
2.5-foot-deep ditch was aligned perpendicular to the runway. If an EMAS
had been installed at the departure end of runway 01, it most likely
would have stopped the accident airplane before it contacted the ditch,
therefore preventing substantial damage to the airplane.
The safety board
realizes that EMAS is not a substitute for, nor a safety equivalent to,
a standard-size [Runway Safety Area]. However,
because EMAS does provide an additional level of safety for those
runways at which it is installed, the board supports the installation
of EMASs at those runways in which the RSA is less than the minimum
standards established in AC 150/5300-13. Therefore, the Safety Board
believes that the FAA should require all 14 CFR Part 139
certificated airports to install EMASs in each RSA available for air
carrier use that could not, with feasible improvements, be made to meet
the minimum standards established by AC 150/5300-13, "Airport Design."
The systems should be installed proactively, not only as part of other runway improvement projects.
The story here for all of you can be found by answering these questions:
-
Does your local airport have the recommended 1,000-foot space at the end of runways, in
case of a landing like we saw at Chicago Midway?
- If your airport
does not have the space for such a ramp at the end of the runway, has
it or will it soon install an EMAS? They work like runaway truck
ramps on mountain passes. The FAA, as you will read below, recommended
two years ago that hundreds of airports should install such systems. A
bill that was recently passed into law is set to encourage more
airports to
build EMAS systems or extend their runway barriers. It requires them to
do one or the other by 2015. According to
the FAA, 284 such airports exist. (Here is an example. See section XI, item 13. The city of Laredo, Texas was awarded an FAA grant this year to build an EMAS ramp.)

here to see EMAS systems in Jamaica, N.Y.; Little Rock, Ark.; Minneapolis-St. Paul, Minn.; Rochester, N.Y.;
Burbank, Calif.; Baton Rouge, La.; Binghampton, N.Y.; Greenville, S.C. and Hyannis, Mass. These systems are
installed in places where there is not enough room to construct the
1,000-foot buffer at the end of a runway.
Recycled Medical Devices
Hospitals
are recycling tracheal tubes, catheter electrodes and other devices in order to
save money -- and the federal government does not require the hospitals to
tell the patients that they are using recycled medical devices. The Washington Post said that there are hospitals in all 50
states that re-process materials intended for one-time use.
The Post said Sunday:
A growing number of U.S.
hospitals […] are saving money by reusing medical devices designated
for one-time use, ignoring the warnings of manufacturers, which will
not vouch for the safety of their reconditioned products.
Hospitals
are not required to tell patients that reconditioned devices will be
used in surgery -- surgeons themselves often do not know. The Food and
Drug Administration regulates the practice, and many hospital
administrators say reusing single-use devices is not only cost
effective but also poses no threat to patients because the instruments
are cleaned with such care that they are as good as new.
Tookie Williams Execution
We still do not know what Gov. Schwarzenegger will decide about granting clemency to
Stanley
"Tookie" Williams, who is currently scheduled to be executed in
California
tomorrow. Williams was a co-founder of the Crips gang, but was later
nominated for a Nobel Peace Prize for his books, written from
death row, warning children about the gang life he led. In 2002, a story in the San Francisco Chronicle included this passage:
Deputy Attorney General Lisa Brault, the prosecution's lawyer in the
(federal) appeal, said Williams was a poor candidate for leniency.
"Having spoken at length with all of the victims' family members, I
think that Mr. Williams is just another murderer that deserves to be
executed," she said. "There's been so many deaths at his hands or the
hands of his followers that I don't think writing a few children's
books erases that."
Here is some additional case background, and
more coverage from the
Chronicle.
"The many facets of Tookie Williams" (AP background story)
Here is a Web site dedicated to lobbying for Williams' clemency. The American Civil Liberties Union filed a friend-of-the-court brief on his behalf [PDF].
There are also some reports of "credible" predictions of civil unrest if Williams is executed.
