A report by French authorities released Friday into the crash of an
Air France plane in the southern Atlantic in 2009 said that pilots failed to follow standard procedures and had not received training for the situation in which they found themselves, dpa reported.
The captain had been resting when the plane's autopilot disconnected following the plane's flight into an area of turbulence, the Bureau of Enquiry and Analysis (BEA) said.
Despite noting that there was an inconsistency in the speeds being shown on their equipment, the two copilots did not follow standard procedure, the report concluded.
"The copilots had received no high altitude training for the "Unreliable IAS" (unreliable speed indications) procedure and manual air craft handling," the report said.
At no point was an announcement made to passengers, the report noted.
On June 1, 2009 Air France Flight 447 was flying from Rio de Janeiro to Paris with 228 people on board when the plane went down some 1,500 kilometres offshore. There were no survivors.
