Rote learning, an extreme example

William Langewiesche has a long article in the NYTimes Magazine about the malfunctions in the Boeing 737. It contains an example of rote learning that I'm parking here just to remind myself of the phenomenon.

At the start, civil aviation in China was a mess, with one of the highest accident rates in the world.

Dave Carbaugh, the former Boeing test pilot, spent his first 10 years with the company traveling the globe to teach customers how to fly its airplanes. He mentioned the challenge of training pilots in Asia. “Those were the rote pilots,” he said, “the guys standing up in the back of a sim. They saw a runaway trim. They saw where and how it was handled in the curriculum — always on Sim Ride No. 3. And so on their Sim Ride No. 3, they handled it correctly, because they knew exactly when it was coming and what was going to happen. But did they get exposed anywhere else? Or did they discuss the issues involved? No. It was just a rote exercise. This is Step No. 25 of learning to fly a 737. Period.” I asked about China specifically. He said: “The Chinese? They were probably the worst.” He spent every other month in China for years. He said: “They saw flying from Beijing to Tianjin as 1,352 steps to do. Yet if they flew from Beijing to Guangzhou, it was 1,550 steps. And they didn’t connect the two. It would get so rote that they just wouldn’t deviate. I remember flying with a captain who would never divert no matter how many problems I gave him. I asked him, ‘How come?’ He said, ‘Because the checklist doesn’t say to divert.’”

That changed over time. With the support of the Chinese government, which went so far as to delegate some regulatory functions to foreigners like Carbaugh, the manufacturers were able to instill a rigorous approach to safety in a small cadre of pilots and managers, who in turn were able to instill it in others. The effort was made not out of the goodness of the manufacturers’ hearts, but out of calculations related to risk and self-preservation. It is widely seen to have been a success. Today the Chinese airlines are some of the safest in the world.
