The specialised website The piles Explains that “the rat is triggered automatically when the two engines are stopped, when one of them breaks down and the electrical generator of the other engine is broken down, when the alternating power supply is completely cut or when the main hydraulic circuits are broken down”.

The black containers saving the flight knowledge, recovered and presently operated by the Indian authorities, may make it potential to make clear this uncertainty.

They certainly comprise sure treasured knowledge for the remainder of the survey, equivalent to recordings of the pilots’ microphones in addition to all their radio transmissions with the management tower. The speculation of an unintentional set off of the rat nonetheless appears unlikely, the administration of Ahmedabad airport – from the place the Air India flight left – having revealed that the pilot had issued a “Mayday”, the commonest alert sign, earlier than the crash …
