>Interesting that someone cited divorce and sleep examples as emotional pleas, reassuring us they are only human. Huh? FAA spends a huge amount of time and energy focusing on human factors, tasks saturation rates and crew resource management. Nothing to do with with argumentum ad passiones, just prudent risk mitigation.

I thought a lot of safety thinking was built around acknowledging that humans don't do everything perfectly all the time.

  It does, and one class of mitigation is to improve automation, which airlines (and their regulators) do all the time. But another class of mitigations is to make the human less error-prone in the first place. This is especially important in preventing failures that were caused by improper management of the automation. Hence the emphasis on rest periods, training, and other mitigations on the human side. In the "swiss cheese" model, a disaster needs to slip through both the human's defenses and the automation's defenses to actually happen. It makes sense to improve both of those layers of defense against disaster, while acknowledging that humans will never be perfect. But at least they can be awake and knowledgable.

Right. Literally every pilot in the US has been taught the IMSAFE mnemonic to assess fitness to fly, even before their first solo in a single-engine piston: Illness, Medication, Stress, Alcohol, Fatigue and Emotion.

I just don’t see how it fit the article. Unless they are surmising the pilots poorly sanityized the data going into the computer because they were having an off day.

  I mean, yes. That is literally exactly what they’re saying. The full quote: > …if there’s a glitch, naturally some pilot somewhere is going to miss it. “Not everyone gets eight hours sleep the night before. Someone is going through a divorce. Someone is not so sharp that morning,” he said. “The sanity check isn’t perfect every day of the week.”
