Are they actually talking about "Stop Bars?"

LAX Runway Status Lights Press Event
Gina Marie, thank you. I appreciate that warm L.A. welcome. Hello
everybody, and thanks for coming out this afternoon.
Today I’m announcing a preliminary agreement between the FAA and the
city to bring a life-saving technology to LAX. It will significantly
boost runway safety without reducing capacity or adding to controller
workload.
It’s an alert system with red lights embedded in the runway pavement
to warn pilots to hold right where they are. The reasoning is simple.
Drivers have stop lights to guide them. Why not pilots? Well now they
will.
We call them runway status lights, and we’re bringing this technology
here because LAX needs it. LAX has had the most runway incursions of
any airport in the country since 2001. There were eight of them last
year, just as there were in ’06 and ’05. That may not sound like a lot
when you consider that LAX had more than 680,000 takeoffs and landings
last year. But let me tell you, that’s eight incursions too many.
Still, the FAA and the city have done a lot over the years to try and
whittle incursions down, but that number has remained fairly constant.
These new runway lights will be one more layer of defense, but it
won’t be the first line of defense.
What L.A. needs to do, first and foremost, to stem runway incursions
is improve the airport layout. The city needs to do on the north
airfield what it’s doing on the south side. That’s how you drive down
incursions.
Until a more comprehensive solution comes along, the FAA and LAX are
continuing to look at stop-gap measures such as runway status lights
to improve safety.
The proof is there that they work. There was an incident recently at
Dallas Fort Worth that illustrates just what I mean.
A few weeks ago, a commercial flight was taxing into position, about
to take off. At that very moment, another plane was about to cross the
runway that it was on.
But instead of taking off, the first plane stayed right where it was,
thanks to the red runway status lights — the same lights that we’ll be
installing at LAX.
We’re looking into that incident at DFW to find out exactly what
happened, but we know for sure that the planes never got close to one
another. Tragedy avoided. The technology worked.
We’re also hearing good things about it out of San Diego, which has a
similar runway light system.
What’s unique about what we’re doing at LAX is that for the first
time, we’re installing the lights on high-speed exit taxiways, which
is fertile ground for incursions.
Here’s something else we know. Pilot error is mostly to blame. It’s
frustrating, because as a pilot myself, I have a hard time
understanding why that’s so.
Runways lights will help where human judgment fails, but — and I’ll
say it again if you didn’t hear me the first time — the ultimate aim
for LAX is to reconfigure the north runways. They’re too close
together. That doesn’t leave much room for error if someone makes a
mistake.
The southern end of the airport doesn’t have that problem, not since
the runways were spaced farther apart.
I appreciate and respect the voices of dissent who feel otherwise
about the situation, but let’s not let politics get in the way of
safety. Any incursion is one too many. And there have been a number of
close calls over the years, including a very serious one here last
summer.
Runway status lights are one way to drive down incursions, but they’re
not the best way. I urge city leaders to do what is best for their
airport and their city and change the layout of the north airfield. I
ask you to do this in the name of safety.
Thank you. And a special thanks to Los Angeles World Airports for the
leadership it’s shown. They’ve been tremendous in smoothing out the
creases to finance the runway light system so it can be deployed
sooner.
I can’t forget to mention one more name who was so instrumental in
getting this project off the ground. Congresswoman Jane Harman. I wish
she were here in person to see this day, but she had to be in
Washington on official business.
Thanks to her and to LAWA, LAX is one step closer to a new era in
safety. The contracts for the runway lights have already gone out.
Construction starts this summer. And we expect LAX to be totally “red”
and ready to go by early next year.
There’s just a couple of things left to do to make it all official,
and one of them is getting the preliminary agreement signed. Before we
do that, we’re going to take your questions. And then I’m going to ask
Gina Marie to join me at the table to and let’s get things moving.

The FAA is also testing new technologies that will alert pilots to
potential runway incursions. One of these, called Runway Status
Lights, is just as it sounds: a series of runway lights, not unlike
traffic lights, that tell pilots whether or not runways are clear.
Surface and terminal surveillance systems, such as ASDE-X and AMASS,
detect the presence and motion of aircraft and vehicles on or near the
runways. The Runway Status Light safety logic then assesses any
possible conflicts with other surface traffic. Red entrance lights
embedded in the pavement are illuminated if the runway is unsafe for
entry or crossing, and red takeoff hold lights are illuminated if the
runway is unsafe for departure. The operational evaluation of the
runway entrance lights using ASDE-X surface surveillance was completed
in June 2005 at Dallas/Ft. Worth International Airport, and the system
showed promising results. The lights were found to be compatible with
the tempo and style of operations at a busy airport with no increase
in controller workload. An enhanced lighting configuration is being
installed on a second runway at Dallas-Ft. Worth this year. Runway
Status Lights with AMASS are currently being tested at San Diego, with
promising results. Based on these tests, the FAA will determine which
airports will receive the alert system.
Other new technologies include an experimental system called the Final
Approach Runway Occupancy Signal (FAROS), which is being tested at the
Long Beach/Daugherty Field Airport in California. FAROS is designed to
prevent accidents on airport runways by activating a flashing light
visible to landing pilots to warn them that the runway is occupied and
hazardous.

In-Pavement Light Emitting Diode (LED) Evaluation
Painted markings on runway, taxiway, and apron surfaces are often
obliterated when covered by even a thin layer of water, there is a
need to provide a more effective method of marking or delineating
critical areas and/or locations on the non-movement and possibly
movement areas on an airport. Conventional in-pavement
(semi-flush/inset) lights can be used; however, they are expensive and
costly to install and maintain.
The commercial lighting industry has recently developed a light strip
system that utilizes a series of encapsulated light emitting diodes
(LED) to provide a continuous line of closely spaced lights. The
string of diode lights can be easily embedded within the pavement
surface so as not to hinder snowplowing operations and, being sealed
or encapsulated, require only a minimum of maintenance. LED devices
are noted for requiring comparatively low level of power for operation
and have demonstrated minimal failure rates.
AAR-411 will evaluate the effectiveness of, and determine the
performance characteristics of these LED light strips for airport use.
Strips will be installed and evaluated at the William J. Hughes
Technical Center.
