Concrete Alternatives
Short runways are an unavoidable problem when there is a shortage of land and it is not possible to have the standard 1,000 feet overrun. Judging by the Tam air disaster, not all country's airports have the technology to prevent major aircraft mishaps, technology such as EMAS. EMAS–Engineered Material Arresting Systems–was developed by the Federal Aviation Administration (FAA) and ESCO (Engineered Arresting Systems Corporation). EMAS acts as a buffer to slow down aircraft that overrun the length of the runway. All it takes is a bed of crushable concrete--cellular cement material that crushes under the weight of an aircraft, resulting in guaranteed deceleration of the aircraft.
Features of Engineered Material Arresting Systems
FAA-approved

Engineered Material Arresting System (EMAS)
Background
The Federal Aviation Administration (FAA) requires that commercial airports, regulated under Part 139 safety rules, have a standard Runway Safety Area (RSA) where possible. At most commercial airports the RSA is 500 feet wide and extends 1000 feet beyond each end of the runway. The FAA has this requirement in the event that an aircraft overruns, undershoots, or veers off the side of the runway. The most dangerous of these incidents are overruns, but since many airports were built before the 1000-foot RSA length was adopted some 20 years ago, the area beyond the end of the runway is where many airports cannot achieve the full standard RSA. This is due to obstacles such as bodies of water, highways, railroads, and populated areas or severe drop-off of terrain.
The FAA has a high-priority program to enhance safety by upgrading the RSAs at commercial airports and provide federal funding to support those upgrades. However, it still may not be practical for some airports to achieve the standard RSA. The FAA, knowing that it would be difficult to achieve a standard RSA at every airport, began conducting research in the 1990s to determine how to ensure maximum safety at airports where the full RSA cannot be obtained. Working in concert with the University of Dayton, the Port Authority of New York and New Jersey, and the Engineered Arresting Systems Corporation (ESCO) of Logan Township, NJ, a new technology emerged to provide an added measure of safety. An Engineered Materials Arresting System (EMAS) uses materials of closely controlled strength and density placed at the end of a runway to stop or greatly slow an aircraft that overruns the runway. The best material found to date is a lightweight, crushable concrete. When an aircraft rolls into an EMAS arrestor bed, the tires of the aircraft sink into the lightweight concrete and the aircraft is decelerated by having to roll through the material.
Benefits of the EMAS Technology
The EMAS technology provides safety benefits in cases where land is not available, where it would be very expensive for the airport sponsor to buy the land off the end of the runway, or where it is otherwise not possible to have the standard 1,000-foot overrun. This technology is now in place at 18 airports with installation under contract at six additional airports. A standard EMAS installation extends 600 feet from the end of the runway. An EMAS arrestor bed can still be installed to help slow or stop an aircraft that overruns the runway, even if less than 600 feet of land is available.
Current FAA Initiatives
The Office of Airports prepared an RSA improvement plan for the runways at approximately 575 commercial airports in 2005. This plan allows the agency to track the progress and to direct federal funds for making all practicable improvements, including the use of EMAS technology.
Presently, the EMAS system developed by ESCO using crushable concrete is the only system that meets the FAA standard. However, FAA is conducting research through the Airport Cooperative Research Program (project number 07-03) that will examine alternatives to the existing approved system. The results of this effort are expected in 2009. More information on the project can be found at the Transportation Research Board website at http://www.trb.org/CRP/ACRP/ACRP.asp.
EMAS Arrestments
To date, there have been four incidents where the technology has worked successfully to keep aircraft from overrunning the runway and in several cases has prevented injury to passengers and damage to the aircraft.
- May 1999: A Saab 340 commuter aircraft overran the runway at JFK
- May 2003: Gemini Cargo MD-11 was safely decelerated at JFK
- January 2005: A Boeing 747 overran the runway at JFK
- July 2006: Mystere Falcon 900 airplane ran off the runway at the Greenville Downtown Airport in South Carolina
EMAS Installations
Currently, EMAS is installed at 24 runway ends at 19 airports in the United States. With plans to install 12 additional EMAS systems at seven more U.S. airports.

Pilot Error Suspected
Authorities believe pilot error caused the tragedy. If confirmed, it would cast doubt that poor runway conditions were to blame.
Pilots had programmed the computerized engine controls -- similar to a car's cruise-control system -- to maintain a speed of about 150 mph. When the plane was about 30 feet off the ground, the pilots correctly switched one of the engines to idle, but did not do so with the other engine. When the plane was braked, the second engine attempted to accelerate to maintain the preset speed.
One of the airplane's thrust reversers, a device used to slow the aircraft, was broken but the manufacturer claims plane is safe to fly with a disabled reverser.
However, it has long been claimed that the short runway at Congonhas is unsafe in rainy conditions. The runway has been the site of problem landings before, and was even closed briefly this year, by court order.
Air traffic controllers fear that government officials will use reports of pilot error to excuse themselves from making further improvements to the air safety system.
Airbus says no evidence of plane fault
A TAM airline Airbus 320 overran the runway while landing at Sao Paulo's Congonhas airport crossed a road and slammed into an airport building, and exploded on July 17.
Available data shows the aircraft's brakes functioned correctly.
But the representative said that one of the engine's throttles was in the 'climb' position.
The plane was also operating with only one of of its two thrust reversers, which are used to help brake the plane upon landing.

No 'Errors' In Sao Paulo, Brazil Plane Crash
The report, presented to Brazilian lawmakers, came from the manufacturers of the Airbus that crashed at Congonhas Airport in Sao Paulo, O Globo TV reported.
However, the same congressional panel that heard the findings by Airbus determined last week that a misaligned engine throttle was likely the cause of the crash.

The Cost of Cheap Air Travel
Airline safety relies on government-provided infrastructure. To put it simply, you can not skimp on airports. Things like long runways, grooved surfaces, overruns, planned SAFE approaches. Brazil dragging its feet is what killed nearly 200 people, no matter what the investigation says.
Airports need standards, and standards need to be enforced. Would the accident have happened on a longer runway that was properly surfaced? The pilots did NOT skid off the end of the runway. When they couldn't stop, the pilots decided t get airborne again.
The mechanics of landing
When landing, a jet gets the main wheels onto the runway, which takes up 1000 or more feet of runway.
The pilot deploys the speed brake lever, then pulls the throttles into reverse thrust. This takes up runway at the rate of 200 feet per second.
So what happens when the jet brakes and the pilot realises it is too slick to stop? The pilot must get the engines back max power--was there adequate time and space for the Airbus to do this? Obviously not.
Are we following in Brazil's footsteps?
The FAA is asking Congress to pawn off federal funding responsibilities for a national system through "user fees" (as our current FAA administrator has asked Congress to do).
Our amazing safety record comes from not skimping, not searching for cost-cutting measures. Will we continue to set the world safety standard or not? Only time will tell.

Infraero Oversight
It was raining in Sao Paulo again yesterday.
Rescue workers have removed 173 badly charred bodies. The three story Tam Cargo center that was hit housed about 55 employees. Of those employees, three were killed, 11 were injured. and five are missing.
The word from officials investigating the crash is that the pilot attempted to take off when he realized the plane couldn't stop.
An emergency meeting of congress was called to discuss the crash.
Dental records are being used to help identify the victims who are charred beyond recognition. All that remains of the airbus is the plane's red tail fin.
It is common knowledge that the runways at Congonhas are too short.
A witness said, "We heard a loud skidding noise and saw the plane cross another lane very quickly, and then the plane disappeared. I felt the heat of the fire ball in my face. The fire was as big as a 25-story building.''
Witnesses feared the fire might trigger other explosions.
The plane's black box is under investigation.
The company producing the Airbus is based in Toulouse, France, a subsidiary of European Aeronautic, Defence & Space Co.
It has been revealed that that particular plane had logged about 20,000 flight hours in 9,300 flights, and was powered by International Aero Engines' engines.
The leader of the opposition in the lower house of congress, Julio Redecker, was one of the passengers.
Ten months ago, a Gol Linhas Aereas Inteligentes SA passenger plane collided in mid-air with a business jet over the Amazon, killing 154 people.

What Is Sauce for the Goose is Sauce for the Gander
The regulation that applies to Silva's plane is " a security rule for transporting the nation's highest executive. "Air force commander Brig. Juniti Saito told a congressional panel during the investigation.
The problem is that one of the reverse thrusters used to slow the planes down during landings — was deactivated on that terribleTAM Airbus A320 crash. TAM Linhas Aereas SA said that according to government-approved safety measures. the plane was safe to fly.
Tell that to the nearly 200 fatalities of the crash: all 187 aboard plus 12 people on the ground.
Speculation as to the cause is currently focused the notoriously short. slick runway and the possibility that the jet's throttles were set in the wrong position.
Congresswoman Luciana Genro said, "It's obvious that no human life is less important than the life of the president of the Republic. The air force should try to stop Airbuses from flying with the reverse thruster deactivated."

Brazil Seizes Flight Control Data
"Come on! Come on! Turn, turn, turn, turn!" cried the co-pilot moments before a final utterance, "Oh no!," was heard. The tape goes blank as the jetliner slammed into a cargo building at 137 mph and exploded.
In the wake of the airliner crash in Sao Paulo last month, Brazil's top prosecutor Matheus Baraldi Magnan, seized records from key flight control centers in response to concern over Brazil's civil aviation system.
Explaining the surprise data impoundment, Magnani said the military hindered his seizure, and "holds on to the information. It is not possible today to know the extent and frequency of problems. Only with that information will it be possible to evaluate and improve the system...The goal is to assure seizure of the incident records, and any information about problems in the air traffic control system, which will allow us to assess the risks passengers and crew face aboard aircraft."
The government confirmed that France and aircraft builder Airbus filed a complaint over leaks of the Tam airlines flight's black box.
The French bureau's response on August third was that "All sorts of information, correct or incorrect, is circulating, along with speculation and attempts at explanations."
"It is a serious error to try to draw conclusions on the basis of incomplete and unanalyzed information."
A transcript of the cockpit voice recorder was released last week by a congressional committee investigating the accident on.
July 17 when the TAM Airbus 320 carrying 187 people overran the runway while landing at Sao Paulo's Congonhas airport, crossed a road and slammed into an airport building.
Brazil Air
Brazil is rethinking its flight patterns
Across the country, frustrated passengers whose flights have been delayed or cancelled are rioting due to the long lines in Brazil's airports. Underpaid and understaffed air traffic controllers are at the hub of a logistical nightmare. More than 10 government agencies oversee aviation.
Baumgartner accused the Brazilian government of "chasing scapegoats" among the Brazilian air traffic controllers instead of "re-engineering the necessary safety oversight and risk assessment to prevent Brazilian civil aviation from falling into deeper chaos."
President Luiz Inácio Lula da Silva promised to get tough on safety and build a new airport in São Paulo to ease congestion. "Our aviation system, in spite of the investments we have made in the expansion and modernization of almost all Brazilian airports, is passing through difficulties." To ease the pressure, several measures are planned like bans on charter, cargo and executive flights to Congonhas. The question is what pressure will such changes actually ease: the stressed airport system, or the government taking the heat for the stressed airport system?
Aviation experts say that the Airbus 320 that crashed at Congonhas was too large for the airport's short runways, that the runway was not textured properly and part of the plane's supplementary braking system was not working. Last February, a federal judge prohibited the landing large types of aircraft at the airport, including Fokker 100, Boeing 737-800 and Boeing 737-700.
Carlos Gilberto Salvador Camacho, director of flight security for the National Union of Pilots, tokd a São Paulo newspaper last week. "There is subliminal pressure from the commercial airlines that if you don't land there you are somehow hurting the companies that rely on their revenues from the passengers."
"What exploded at Congonhas was not just the TAM jet and its almost 200 victims, but the credibility of the Brazilian system of civil aviation. Ten months ago, the country felt the impact of the worst disaster in its history of civil aviation, an incident which lifted the veil off the chaos in the industry, and we completely ignored it." wrote Cezar Britto, the national president of the Order of Brazilian Lawyers after the Congonhas crash.

Tam Air Crash Lawsuit
198 other people who were killed when the Tam Airbus A320 skidded off a rainy runway at Sao Paulo's Congonhas Airport.
TAM is charged with negligence. The plane should have been grounded because one of its thrust reversers was not working. Defendants include Goodrich, the manufacturer of the aircraft's braking system and IAE, which assembled the plane's engine.
"From the evidence gathered so far, it's clear that TAM knew there were problems with the aircraft," Steven C. Marks, an attorney at Miami law firm Podhurst Orseck, said in the statement. "Had (the thrust reverser) been operational, it may have prevented this accident."
The lawsuit seeks unspecified financial damages.
IAE is United Technologies Corp. Pratt & Whitney, Britain's Rolls-Royce Plc, Japan's Aero Engines Corp. and Germany's MTU Aero Engones.
The firm that filed the suit is also representing several families in a suit concerning an earlier crash in the Amazon this year.

Fired: Head of Brazil airport authority
The TAM crash is actually the second major plane crash in Brazil in 10 months. In September, 154 people were killed when a Boeing 737 clipped wings in mid-air with a private jet and crashed in the Amazon jungle.
The replacement is Sergio Gaudenzi, head of the Brazilian Space Agency. An official announcement is not expected until Monday.
Pereira has been under pressure to step down since the Airbus A320 crash. 187 people aboard the TAM flight and 12 on the ground were killed in the accident The crash caused a national outcry for improvement in air safety.
Gaudenzi's first task will be to restore normalcy at Brazilian airports.In Brazil that many passengers are now canceling flights and taking buses instead.
Many travelers avoid Brazil altogether.
2007/08/03
Radar Failure
The radar was out from midnight until 2:30 am, and caused by an electrical problem. Travellers found themselves trapped in airports, unable to catch flights home. There was mass confusion in spite of the president's speech primishing safety measures.
"Our aviation system, in spite of the investments we have made in expansion and modernization of almost all Brazilian airports, is passing through difficulties,'' Silva said. ``The security of our aviation system is compatible with all the international standards. We cannot lose sight of this.''
A new airport location will be chosen within 90 days but will take five years to build and is not a high priority. Congonhas, the nation's busiest airport, has a slick, short runway considered a likely factor in the crash of the TAM flight that killed nearly 200 people; and the planned repair and remediation does have priority. The crash was the country's worst disaster until Tuesday's accident and it exposed widespread problems with the country's air traffic control system.
Analysis of the recorded conversations should be available within a few weeks.
