Disturbing flight over Europe. Suspected failure of both engines

Boeing 787-8 Air India

The passengers of flight AI117 landed in Birmingham thanks to the emergency RAT system. It turns on, among others: in cases of failure of both engines.

On Saturday, an Air India plane landed disturbingly in Birmingham. The Boeing 787-7 has deployed a thrust air turbine (RAT), which only turns on automatically in the event of a major emergency. These include failures of both engines, as well as critically low pressures recorded by all three hydraulic systems. According to the preliminary analysis, in this case all the parameters tested were correct. Despite this, according to the BBC, the plane was grounded in order to carry out necessary, more thorough inspections.

Dangerous flight over Europe

The Air India plane, flying from Amritsar, India, to Birmingham on Saturday, October 4, landed at the British airport after 7 p.m. thanks to the efficient RAT system. The Dreamliner opened the thrust air turbine automatically due to detected irregularities. However, after landing, the airline said that “all electrical and hydraulic parameters were found to be correct.”

However, the plane was stopped at the airport for further inspections and the return flight to India was ultimately cancelled. Accommodation was provided to injured passengers waiting for the next connection.

This is how RAT works

RAT, a small propeller extending from the bottom of the aircraft, is a device that generates the energy necessary for the operation of the aircraft’s basic devices and systems at critical moments, such as the failure of both engines or low cabin pressure. “It is assumed that the same RAT system was activated just before the crash of an Air India Dreamliner bound for London in June, which killed 260 people, including 241 passengers,” reports the BBC.

This event was the first-ever fatal crash of a Boeing 787 Dreamliner and resulted in mass inspections of this aircraft model around the world.
