After 13 years from the accident, the trial of Air France and Airbus for the accident of flight AF447 Rio-Paris in 2009 began in Paris.

On this incident, I wondered why Airbus' A330 management software did not consider that   " there is a reaction to an effect  ".

In the specific case, "the effect" was the loss of sustained speed of the aircraft reported by the Pitot tubes regardless of whether "true" or "false" because it was due to the ice in the Pitot tubes, while the "reaction" was not considered by the software was to ignore two fundamental aspects detected by the flight data, namely that the aircraft continued to fly at its altitude of cruising "level" and the engines were   " regularly thrust "  which contrasted with a loss of airspeed of the aircraft reported by the Pitot tubes.

If this inconsistency was reported to the pilots and the software continued to control the plane on the leveled flight altitude with the engines regularly in thrust, instead of leaving the control of the plane to the pilots, I believe that today we would never have talked about this tragic flight  and, above all, with 228 victims.
