Hi,
Le Figaro - France : Les pilotes mal formés au «décrochage» des avions
INFO LE FIGARO - Several accidents have revealed that the procedures to recover an airplane that could lead to crash landed.
Dazed in the cockpits. Reportedly, a major work is underway to develop safety procedures for crews of all companies in the world. Airbus, Boeing, Bombardier, Embraer, Air France as all companies ... Everybody is associated with what is now a major issue in aviation safety. Airbus announced this great project mid-March to its airline customers. Several recent accidents have revealed that the procedures "Stall" implemented in the event of stalling an airplane are not appropriate, and in some cases, they prevent the crew out of this dangerous situation, and sometimes dramatic. There is talk of dropping out of the plane, but it is actually the wing stalls.
In conventional flight conditions, the air streams flow around the wing and conform to the shape. However, at too high incidence (the angle of the wing with the air), not reattach airflow over the airfoil. The lift of the aircraft decreases. He falls or continues its path because of its inertia and can only crash. In contrast, high speed, airflow can reach the speed of sound. This creates a shock wave that can cause loss of control of the aircraft.
Dropout can occur at low speed, it is called "low stall speed," or high speed, it is called "high speed stall.
Today in all cockpits, the procedure in case of stalling to full throttle to minimize loss of altitude. "This procedure has been pushed by mistake by U.S. authorities," said one familiar with the matter. In a few weeks, the new procedure will recommend only a control stick to reduce the incidence, that is to say things slightly, nosed the plane. This change of method should be common to Airbus and Boeing. "The whole aviation industry has gone astray for more than a decade," says one close to the matter.
From Air France, the drivers are embarrassed to armholes because they do not test flight and can not have a final stance on the issue. They can only rely on the advice of manufacturers. "Air France Airbus maintains its commitment to change this procedure on all aircraft in the world fleet," said Stephen Lichtenberger, CEO of Flight Safety at Air France. The analysis of recent events suggest, in fact, that this change is necessary. " The company says it lights will implement the new procedure as soon as possible, "as soon as we have been addressed by manufacturers having been validated by the certification authorities, namely the European Agency for Safety (EASA).
Flight test
The other major issue is that of training. For today, not a flight simulator can not recreate the settings related to a stall and thus cause the drivers to cope. "We can train pilots to recover from a situation close to the stall, said an instructor of Air France, but not to recover from a stall." "Procedures have been made for people who have never lived on heavy airplane stall, said Claude Lelaie, head of security at Airbus. Only test pilots who know the stall. According to our information, Airbus will offer its customers boarding their flight instructors on board to offer test drive in situ. However, it is unrealistic to imagine all the drivers in the world to flight testing to practice stall recovery.
I remember that Airbus telling the training for stall recovery was not necessary for their aircrafts ...
Someone can confirm or infirm this ?
More from the french newspapers ....

Air France recently offered tickets to the families of victims of the crash of Flight AF447 Paris-Rio by offering to join Paris on exactly the same flight as the one who died tragically last year, reports the website of Der Spiegel.
Families living in Brazil did not really need this unfortunate coincidence: the flight was offered to attend a ceremony at the Pere Lachaise Cemetery where a memorial in honor of the 228 people who died on June 1, 2009 must be opened. More than 120 victims' relatives planned to travel to Paris on this occasion. But many have not hidden their misunderstanding after learning of the flight schedule and mark-up is keeping them take: flight AF445, starting Sunday night in Rio de Janeiro aboard a Airbus.
"This is exactly the same flight as one that took away our loved ones," said Maarten van Sluys, the president of an association of families of victims at the site of German newspaper. "I do not know what were the intentions of Air France, but it's bad taste and no respect for our very fragile emotional state," he added.
Airbus used for the flight, whose name was changed from AF447 to AF445, would be far from completed, which upset a little van Sluys: "They just need to fill a plane and have decided to to our group of 100 people. "
The victims' association has requested that Air France offers flights to another group, one of the two Boeings that connect Brazil and France every day to avoid having to relive the last moments of their loved ones, that an Air France pilot was described in the columns in Slate. "We would feel much better," said Van Sluys.
Wednesday, April 28, the Office of Investigations and Analysis (BEA) announced that the research of black boxes and the wreckage of flight AF 447, who have still not been found eleven months after the tragedy, would continue . The issue of compensation also remains a thorny issue, a lawyer representing families of victims said Tuesday, April 27 insurers that Air France offered an amicable compensation differ depending on the nationality of the victims: 2.98 million euros per person in the United States, 560,000 euros to 186,000 euros in Brazil and Europe.
