The analysis of black boxes containing the recording of the flight data and conversations in the cockpit seems to dismiss any technical problem.

The apparatus is not in question, any more than 5G … The survey opened by the Office of Investigation and Analysis (BEA) on the causes of the “serious incident”, concerning the flight AF011 of April 4, connecting New York-JFK to Paris-CDG in B777, during the landing phase in Roissy, is oriented towards a responsibility of the pilots, according to a point on the investigations broadcast on Wednesday.
As the Parisian airport approaches, the crew had made a gas discount when he was about to land. The plane, with on board 177 passengers and fifteen crew members, had finally landed without incident, after a second approach.

No dysfunction alarm
“We put the gases therefore, the flight command problem, the plane did almost anything,” the pilot explained to the control tower, according to audio extracts from exchanges between the cockpit And the tower, posted online online. The analysis of black boxes containing the recording of flight data (FDR) and conversations in the cockpit (CVR) seems to dismiss any technical problem. “No dysfunction alarm was triggered during the event. No anomaly has been observed on the plane,” says the BEA.
different perception of the situation
All the action took place in less than a minute, details the investigation office. While he was at an altitude of 340 meters, a different perception of the situation between the captain and the co -pilot pushed them to interrupt the descent and put the gases. This did not seem justified, because “until the gas delivery, the trajectory remained in the stabilization criteria of the operator”, according to the Bea.
The “plate”, that is to say the rise of ascent, was then too important for this type of maneuver, he believes. This has led to a desynchronization of pitch commands – which make it possible to determine the angle of the plate – “due to opposite efforts”: “The captain maintains the pitching command slightly to prick, while the co -pilot applies , on several occasions, more marked actions to rekle. “Once stabilized, the crew” analyzes the situation, without having perceived the antagonistic actions on the orders “, adds the BEA.
Solicited by the France-Presse agency, the company said that it “continues to bring its full collaboration to the investigation”. It “recalls that the gas delivery procedure is defined by the aeronautical manufacturers and Air France as a normal procedure, which goes in the direction of safety”.
“The crews are trained and regularly drawn to these procedures practiced by all airlines”, she adds, recalling that “the safety of flights, its customers and its crews is an absolute imperative” .
