explains that sequence of events in the crash that killed all 228 people onboard the flight from Rio de Janeiro to Paris can be segmented into two distinct phases.
In the first phase, the pilots were dealing with the failure of speed readings that are almost certain to be linked to iced-over pitot tubes. The second phase began when speed indications returned to normal and the aircraft was at the edge of its flight envelope but under control and not stalled. Phase two also coincided with the captain’s return to the cockpit from an agreed-upon rest.
AF447 would not have crashed if the aircraft had been of an older generation. “Highly automated aircraft have saved many lives, but they fail differently than aircraft of 20 years ago,” he says. He sees it as a “failure of the industry” that pilot training has not kept in step with the latest aircraft technologies. He also argues for improved upset recovery training, as “we are not explicitly training that” and the AF447 A330 “seems to have had pitch-and-roll authority all the way down to the water.”
