Corre pelos fóruns e blogs especializados que uma linha áerea dos EUA está fazendo simulações do acidente com o AF 447 a partir do cenário conhecido.  Eis a descrição da simulação e seu resultado:

The scenario was conducted several times and the results at the end of each scenario produced consistent findings.

In an A330 simulator at FL 350 [35,000 feet] with a gross weight of 210 tonnes in ISA+10, with icing selected, the aircraft approaches a thunderstorm with a high intensity of turbulence. Due to the extreme turbulence, the autopilot disengages. Shortly thereafter a malfunction is selected to block both captain and first officer’s pitot tubes to replicate extreme ice formation.

The airplane reverts to alternate law with protection lost. There is a speed flag on both the captain and fo’s PFD [Primary Flight Display]. The severe turbulence activates repeated stall warnings. Manual thrust is being used at this time. The speed on the standby altimeter is reading 240kts or thereabouts with MACH 0.72. (From the GPS the ground speed is 350 kts or thereabouts. It is very difficult to read the instruments and ECAM warnings [fault and operational warnings].)

Updrafts take the aircraft up to FL 370 and produces a negative G of 0.2. The aircraft then enters severe downdrafts and the rate of descent averages more than 19,000 fpm [feet per minute]. The instinctive reaction is to pull on the stick to arrest the rate of descent. The aircraft shakes and buffets violently. The G force on the [pilot display] reads +5 but the instructor’s panel shows +8. The aircraft breaks up in flight around 20,000 ft.

After several attempts at this with all results being equal one could not see AF447 sending out any distress signals if this is what happened to them.” [grifo meu]


A New Scientist tem um artigo dizendo que o acidente do AF 447 fará os construtores de aviões repensarem a filosofia de substituir o alumínio na estrutura do avião por compósitos plásticos, mais leves.

Acho difícil. Gente boa e experiente diz que uma boa tempestade é capaz de rasgar ao meio qualquer avião, independente do que ele seja feito.
