David Greenberg, a former Delta Air Lines executive who was hired at Korean Air to oversee pilot training and safety, said aircraft manufacturers, airlines and the FAA embraced the idea that automation could make flying safer, but more recently began to worry about the times when automation can't carry the day.
"The focus started to shift back to being capable of using the automation as an assist to reduce workload in the right circumstance, but being capable also of taking over and flying the old way," Greenberg said.
"In Asia, it's very normal to rely, in my view, excessively on automation," he said, "partly because the manufacturers stress that the airplanes are easy to learn and easy to train on and very safe because the automation narrows the gap between skill and required skill."
