Crashed Indonesia jet's recorder has two hours of cockpit voices
Indonesian investigators will start analyzing next week more than two hours of conversation held in the cockpit voice recorder of a jet that crashed into the Java Sea in October as they seek to unravel the cause of the nation’s worst aviation disaster in two decades.

Each aircraft has two AOA sensors. I used to be a component failure engineer. I saw the data of the two AOA sensors in another article. The pilot's side AOA sensor data graph indicated that there was high levels of static entering the system and the computer was reacting to the static. The sensor was replaced but the ground test is inadequate to detect static interference when the aircraft is motionless. The cabling from the sensor to the computer may have been damaged during the assembly phase and allowed static charges to enter. Boeing can remedy this by comparing both sensor readings and alert the crew and maintenance if there is an anomaly between the readings. The FDR data indicated there was a problem even as the aircraft was taxiing for take off which brings me to the static interference conclusion. The skin of the aircraft will produce static interference.
You are very correct sir. The problem my not be in just the design, but in management and bean counters. The Challenger disaster is a perfect example. We are going to fly even if the engineers tell us the o-rings in the boosters will not seal at freezing temperatures.
Flight control systems are to designed as fail safe. The AOA sensors should be voted and if they disagree out of limit, the system should by shut down. The more complex the flight control systems become, the more poor design decisions are made. For example side stick controllers that are not linked to each other.
IIRC this airplane had previously been written up for spurious AoA issues. Perhaps the recordings of the other crew’s experience regarding this is captured in the other 1+45.
What a horrible thing to have to listen to; I'm glad it isn't my job, and hope it doesn't become public.
If it's no Boeing Im not...ohh wait...
No reason we can’t steam the CVR.... nvm the GgoInglight connection speed is horriable....
