A loss of power from both engines is seen as the most likely cause of the Air India Boeing 787-8 Dreamliner crash on June 12, which killed more than 270 people .
According to former US Navy pilot Steve Scheibner, interviewed by CNBC TV, the video of the plane's take-off shows and hears the activation of the 'Ram Air Turbine' (Rat) , a device that is activated automatically in the event of a serious failure of the two engines or the collapse of the hydraulic or electronic systems.
The Rat uses wind speed to generate emergency thrust.
Indian Air Force pilot Ehsan Khalid, quoted by the Indian television website NDTV, said that " a failure of the two engines is the hypothesis of almost everyone. The only survivor of the crash said he heard a sound, which could be the activation of the RAT ". According to Khalid, "an electrical failure, in certain conditions, could have led to the simultaneous shutdown of the two engines. If there had been a difference of just two seconds, there would have been a turn to the right or left. Instead they shut down together. This could have happened only because of a software malfunction, caused by a wrong signal to the sensors, which led to an electrical failure".
According to aerospace professor Aditya Paranjape, interviewed by Ndtv, " planes are designed to take off even with a single engine. But in the video we do not see the take-off maneuver with a single engine. The loss of power is identical on both sides ."
In recent days, the images shared on social media by a passenger of the crashed Boeing and taken during the flight preceding the disaster had caused discussion. The continuous failures of the aircraft's electrical system were documented, with lights and screens not working .
