Air India Plane Crash: Did both the ‘Electrical Failure’ B787’s power failure fail fail? , Bharat News
Mumbai: Competrating about the principles caused by AI 171 has generated a new set of potential explanations. Among them, the question of them is that 787 of Boeing replaced the traditional pneumatic and hydraulic system with electrical systems – to make the aircraft lighter to save the cost of fuel and maintenance – whether there is a failure of an electrical system.There is no consensus. But as the pilots continue to search for the answer, the failure of the electrical system has emerged as one of the latest efforts by some people to explain the tragedy.All principles begin with the basis that the loan Survivor heard a bounce, which may indicate a single engine failure. It would not have crashed a modern aircraft? So what else went wrong? Did the second engine fail or was it something else?Dual engine failures are rare events: seven examples have been recorded in the last seven decades, worldwide. This caused Bird Strike (US Airways Hudson River Landing 2009), wrong engine shutdown (1989 British Midland Flight 92, technical issues were incorrectly shut down of good engine) and fuel contamination or starvation. On June 12, the possibility of bird strike in the case of AI 171 accident has been rejected to a large extent.But B787 is a “more-electric” aircraft. Therefore, pilots and experts are looking at this accident differently. A senior B787 commander said: “The boom sound indicates that it is very likely that one of the two engines was a partial or full shutdown.” But what happened after that?Did the pilots shut down a good engine, like in the first accident? But many pilots stated that the process of closing the fuel in a malfunction engine starts at only 400 feet and it takes some time to execute – the aircraft crashed before completion.Did “Startal Effect” – Sudden, involuntary reaction to the sudden, unexpected event – forget pilots that they had to return the landing gear? Or, flaps (there were instruments on the followed edge of a wing, which generate lifts at low speed) retreated instead of landing gear? But as the B787 commander said: “Even if it happened, with an engine intact, the aircraft could safely return and come to the ground”.It is both-engine-down landscape that some pilots are thinking about electric failure. “Initial assessment indicates that at some points one or more VFSGS (variable frequency starter generator: these starting engine and providing main electrical power during flight) may fail or is electrically separated, resulting in partial or total damage to engine control,” a senior airbus commander said, which is flew from a wide-bodied aircraft.
