Faulty data misled pilot in 2009 Air France plane crash: Report

July 6, 2012

Le Bourget (France), July 6: A combination of faulty sensors and mistakes by inadequately trained pilots caused an Air France jet to plunge into the Atlantic Ocean in 2009, killing all 228 people aboard in the airline's deadliest ever crash, French investigators said on Thursday.

Investigators are urging better instruction for pilots on flying manually at high altitudes and stricter plane certification rules as a result of a three-year investigation into what happened to Flight 447.

Airbus, manufacturer of the A330 plane, said in a statement that it is working to improve speed sensors known as pitot tubes and making other efforts to avoid future such accidents. Air France stressed the equipment troubles and insisted the pilots "acted in line with the information provided by the cockpit instruments and systems. .... The reading of the various data did not enable them to apply the appropriate action."


But the Bureau for Investigations and Analysis' findings raised broader concerns about training for pilots worldwide flying high-tech planes when confronted with a high-altitude crisis.

The report also could have legal implications: A separate French judicial investigation is still under way, and Air France and Airbus have been handed preliminary manslaughter charges.

The bureau's analysis lists a combination of "human and technical factors" behind the crash. The plane flying from Rio de Janeiro to Paris slammed into the sea during a nighttime thunderstorm on June 1, 2009.

Some families of victims felt investigators didn't focus hard enough on the equipment problems, saying the two pilots at the controls were doing what they could while faced with a barrage of inaccurate information.

Ice crystals that blocked the pitot tubes were the "unleashing event" that set off the plane's troubles, chief investigator Alain Bouillard said. The plane's autopilot shut off and the co-pilots had to fly manually, while a succession of alarms were going off. The captain was on a rest break.

In one fatal decision, the report says, one of the co-pilots nosed the Airbus A330 upward during a stall - instead of downward, as he should have - because of false data from sensors about the plane's position. Mr Bouillard said that was an "important element" of the cause of the crash.

He said the two pilots at the controls never understood that the plane was in a stall. He said only a well-experienced crew with a clear understanding of the situation could have stabilized the plane in those conditions.

"In this case, the crew was in a state of near-total loss of control," Mr Bouillard said.

Robert Soulas, who lost his daughter and son-in-law in the crash, says investigators said the flight director system indicated the "erroneous information" that the plane was diving downward, "and therefore to compensate, the pilot had a tendency to pull on the throttle to make it rise up."

However, the plane was in a stall instead. A basic maneuver for stall recovery, which pilots are taught at the outset of their flight training, is to push the yoke forward and apply full throttle to lower the nose of the plane and build up speed. But because the pilot thought the plane was diving, he nosed up.

Some families of people who died in the crash showed sympathy toward the pilots, saying they were dealing with bad equipment in an exceptionally challenging situation.

Mr Soulas noted that manufacturers had known for years about problems with the plane's speed sensors freezing over, but didn't order the faulty models systematically replaced until after the crash.

Pilot Gerard Arnoux said, "A normal pilot on a normal airliner follows" the signals on the flight director system, which tells them to go left, right, up or down.

Central to this accident is the fact that when the automation failed, the pilots were presented with conflicting information which was obviously incorrect, said William Voss, president of the Flight Safety Foundation in Alexandria, Virginia. But they were unable to look through this and understand what the aircraft was actually doing.

"Pilots a generation ago would have done that and understand what was going on, but (the AF447 pilots) were so conditioned to rely on the automation that they were unable to do this," he said.

"This is a problem not just limited to Air France or Airbus," Mr Voss said. "It's a problem we're seeing around the world because pilots are being conditioned to treat automated processed data as truth, and not compare it with the raw information that lies underneath."

The final report included a study of the plane's black box flight recorders, uncovered in a costly and extraordinarily complex search in the ocean depths.

Lais Seba, the mother of 31-year-old victim Luciana Clarkson Seba, said "it's going to be forever difficult" for survivors to deal with the loss of their loved-ones.

"We are surviving," she said. "We live one day at a time, with lots of pain, and always missing her."

United Nations, Apr 2: The global economy could shrink by up to one per cent in 2020 due to the coronavirus pandemic, a reversal from the previous forecast of 2.5 per cent growth, the UN has said, warning that it may contract even further if restrictions on the economic activities are extended without adequate fiscal responses.

The analysis by the UN Department of Economic and Social Affairs (DESA) said the COVID-19 pandemic is disrupting global supply chains and international trade. With nearly 100 countries closing national borders during the past month, the movement of people and tourism flows have come to a screeching halt.

"Millions of workers in these countries are facing the bleak prospect of losing their jobs. Governments are considering and rolling out large stimulus packages to avert a sharp downturn of their economies which could potentially plunge the global economy into a deep recession. In the worst-case scenario, the world economy could contract by 0.9 per cent in 2020," the DESA said, adding that the world economy had contracted by 1.7 per cent during the global financial crisis in 2009.

It added that the contraction could be even higher if governments fail to provide income support and help boost consumer spending.

The analysis noted that before the outbreak of the COVID-19, world output was expected to expand at a modest pace of 2.5 per cent in 2020, as reported in the World Economic Situation and Prospects 2020.

Taking into account rapidly changing economic conditions, the UN DESA's World Economic Forecasting Model has estimated best and worst-case scenarios for global growth in 2020.

In the best-case scenario with moderate declines in private consumption, investment and exports and offsetting increases in government spending in the G-7 countries and China global growth would fall to 1.2 per cent in 2020.

"In the worst-case scenario, the global output would contract by 0.9 per cent instead of growing by 2.5 per cent in 2020," it said, adding that the scenario is based on demand-side shocks of different magnitudes to China, Japan, South Korea, the US and the EU, as well as an oil price decline of 50 per cent against our baseline of USD 61 per barrel.

The severity of the economic impact will largely depend on two factors - the duration of restrictions on the movement of people and economic activities in major economies; and the actual size and efficacy of fiscal responses to the crisis.

A well-designed fiscal stimulus package, prioritising health spending to contain the spread of the virus and providing income support to households most affected by the pandemic would help to minimise the likelihood of a deep economic recession, it said.

According to the forecast, lockdowns in Europe and North America are hitting the service sector hard, particularly industries that involve physical interactions such as retail trade, leisure and hospitality, recreation and transportation services. Collectively, such industries account for more than a quarter of all jobs in these economies.

The DESA said as businesses lose revenue, unemployment is likely to increase sharply, transforming a supply-side shock to a wider demand-side shock for the economy.

Against this backdrop, the UN-DESA is joining a chorus of voices across the UN system calling for well-designed fiscal stimulus packages which prioritize health spending and support households most affected by the pandemic.

Urgent and bold policy measures are needed, not only to contain the pandemic and save lives, but also to protect the most vulnerable in our societies from economic ruin and to sustain economic growth and financial stability, Under-Secretary-General for Economic and Social Affairs Liu Zhenmin said.

The analysis also warns that the adverse effects of prolonged economic restrictions in developed economies will soon spill over to developing countries via trade and investment channels.

A sharp decline in consumer spending in the European Union and the United States will reduce imports of consumer goods from developing countries.

Developing countries, particularly those dependent on tourism and commodity exports, face heightened economic risks. Global manufacturing production could contract significantly, and the plummeting number of travellers is likely to hurt the tourism sector in small island developing States, which employs millions of low-skilled workers, it said.

Meanwhile, the decline in commodity-related revenues and a reversal of capital flows are increasing the likelihood of debt distress for many nations. Governments may be forced to curtail public expenditure at a time when they need to ramp up spending to contain the pandemic and support consumption and investment.

UN Chief Economist and Assistant Secretary-General for Economic Development Elliot Harris said the collective goal must be a resilient recovery which puts the planet back on a sustainable track. We must not lose sight how it is affecting the most vulnerable population and what that means for sustainable development, he said.

The alarms raised by UN-DESA echo another report, released on March 31, in which UN experts issued a broad appeal for a large-scale, coordinated, comprehensive multilateral response amounting to at least 10 per cent of global gross domestic product (GDP).

According to estimates by the Johns Hopkins University, confirmed coronavirus cases across the world now stand at over 932,600 and over 42,000 deaths.

Amsterdam, Jun 18: A statue of Mahatma Gandhi has been vandalised here in the capital of Netherlands by unknown miscreants with graffiti and spray painting, amid a wave of attacks on controversial figures following the protests around the world after the custodial killing of African-American George Floyd, according to media reports.

The statue of Gandhi on the Churchilllaan in Amsterdam was covered with red paint and the pedestal has 'racist' and an abbreviation for an expletive against the police chalked on it, Metro, the Dutch newspaper, reported.

According to alderman Rutger Groot Wassink, the municipality will file a declaration for daubing.

"Obviously, we are opposed to any form of vandalism and daubing of these things is completely unacceptable," the city official was quoted as saying by the AD.nl.

"It is logical that we will file a declaration, the image will be cleaned," Wassink said.

It is not yet known who is behind the daubing. An employee of the Kunstwacht, who provides maintenance and repairs, says that the cleaning work can take hours.

A 75-year-old man saw the daubs on Wednesday and called the municipality. “I have lived here for forty years and I have never experienced this. I have been watching the statue for years," the man said.

Since the death of 46-year-old Floyd on May 25 in Minneapolis, US, and subsequent worldwide Black Lives Matter protests, there has been much debate about street names and statues of people with a colonial past. All over the world, statues of controversial historical figures are brought down or defaced.

Recently, images and buildings have been defaced in various places that refer to the colonial past of the Netherlands, including the Tropenmuseum in Amsterdam and the statue of Piet Hein in Rotterdam. These are anti-racist expressions that follow the death of Floyd through a white police officer, Metro reported.

Gandhi was known as a champion of human rights and non-violence. But in his twenties, which he spent in South Africa, he still called black people “troublesome, very dirty and they live like beasts” and found that the white people were the “dominant race”. Later he renounced those ideas, the report added.

The statue was unveiled on the Churchillaan on October 2, 1990 in honour of Gandhi's 121st birthday.

The design was made by the sculptor Karel Gomes, who died in 2016. At the time, the plan for the statue came from the Hindu organisation Triveda.

Gandhi is depicted walking, featuring robes around the body, slippers on the feet, a book in one hand and a stick in the other.

Pentagon, Jan 25: Thirty-four US troops had been diagnosed with concussions and traumatic brain injury (TBI) as a result of the January 8 Iranian missile attack on two military bases in Iraq housing American soldiers, the Pentagon said.

"Eight service members who were previously transported to Germany have been brought to the US, they would continue to receive treatment in the US either at Walter Reed or their home bases," Pentagon spokesman Jonathan Hoffman told the media on Friday.

Hoffman said that nine service members were still undergoing treatment in Germany, and the rest of the 17 injured troops have already returned to duty in Iraq, reports Xinhua news agency.

Lat week, the US military had said that 11 service members were treated for concussion symptoms due to the missile attacks.

Hoffman noted that the symptoms "are late developing and manifested over a period of time".

In retaliation for the killing of Iranian Major General Qasem Soleimani in an American drone attack on January 3 in Baghdad, Tehran launched over 13 ballistic missiles on the two military bases in Anbar and near the city of Erbil.

US military initially said that no casualty was reported from the Iranian attack. President Donald Trump then downplayed the seriousness of those injures.

"I heard that they had headaches and a couple of other things, but I would say and I can report that it's not very serious," Trump told reporters on Wednesday at a press conference in Davos, Switzerland.

More than 5,000 US troops are deployed in Iraq to support the country's forces in the battle against Islamic State militants.
