Though they're not perfect. They said that one pilot is supposed to read the item, the other pilot say the answer, and the first pilot visually confirm it; but at 1:42, I noticed the first pilot say "emergency exit lights", hear the confirmation, and move to the next item without her eyes moving away from the list.
I'm not sure which of several possible conclusions to draw from that. ("Humans suck", "it is indeed staged", "the procedure has enough redundancy that the chance they're both careless on a given step is small", "the pilots feel that the emergency exit lights aren't particularly important", ...)
A: “Passing control”
B: “Taking control”
A: “You have control”
B: “I have control”
This is how I remember it (6174, UH-1Y).
A: "Belay on?"
B: "Belay on"
A: "Climbing"
B: "Climb on"
Then the climber begins.
It's interesting to me that highly regulated and totally unregulated activities have evolved extremely similar processes. I suppose having your life on the line is a good motivator to follow best practices.
"You have the control."
"I have the control."
IDK if it changes between aircraft types, commercial/private/military cultures, or if it's just coincidence.
"Flaps up selected"
"Flaps are indicating up"
There's a lot to learn from the way airplanes are engineered and operated.
For certain procedures we had a second party (“reader”) observing and acknowledging each part of each step.
Operator (Gesturing anti-clockwise while pointing at valve XYZ) Operator: Opening valve XYZ. Reader: Opening valve XYZ, aye. Operator: Valve XYZ is open. Reader: Valve XYZ is open, aye. Operator: Indications of flow Reader: Indications of flow, aye.
People can still get complacent, and things can still get missed but the deliberate mentality goes a long way. Now when GitHub makes me type out the repository name before I can delete it, I sometimes copy/paste... YOLO.
Like when clicking on a file in a directory you just entered and looking for the file, the observer can literally locate and point to the file for the mouse user 5-10x faster than the mouse operator.
The observer seems to interpret the information that results from the directory listing faster than the person who just did the double-click to enter the directory because they don't have the muscle coordination context switch and can immediately move to interpreting the results.
It's probably because mouse manipulation uses brain infrastructure that is more recently evolved, but observe-react is a lot earlier in the brain processing pipeline evolutionarily, and a lot more refined/involved.
