So, the pilots misread the weather radar, flew into bad weather, airspeed indicators failed, automation degraded to the point of unusability, plane got hard to fly, pilots could not handle the workload and the plane met the sea - that is the conjecture so far.
The only way this can and will get handled is by improving the automatic systems on board - at this stage pilots with rudimentary flying ability have become the industry standard - and retraining *all* of the existing pilots to better handle the workload of actually flying the planes is hopeless. The people who design the automation are the ones who really fly these complex and much exported aircraft.
So the answer to too much automation is more automation?
