Exclusive: A400M probe focuses on impact of accidental data wipe
...Yet as the pilots took off, another safety feature came into play only to turn against the crew, industry experts said.
Without the vital data parameters, information from the engines is effectively meaningless to the computers controlling them. The automatic response is to hunker down and prevent what would usually be a single engine problem causing more damage.
This is what the computers apparently did on the doomed flight, just as they were designed to do.
"Nobody imagined a problem like this could happen to three engines," a person familiar with the 12-year-old project said.
basically some torque calibration data got wiped during software installation/checkout. Missing that data, computers decided engines were maybe harmed and to prevent further damage- simply shut down- Three out of four engines..
HAL wins again !!
So much for ' fail safe' modes due to garbaged data...
