Evidence stage
ConstraintFailure, rollback, regulation or cost is suppressing adoption. Can lower an assessment or widen its uncertainty.
Tasks this bears on
The decision that is signed
Accepting the aircraft, the fuel, the weather and the plan — and being the person named when any of them turns out to have been wrong.
Still human-led✓ Evidence-backed
Where this applies
United States. The federal operating rule states that the pilot in command of an aircraft is directly responsible for, and is the final authority as to, the operation of that aircraft, and that in an in-flight emergency requiring immediate action the pilot in command may deviate from any rule of that part to the extent required to meet the emergency. It names a person as the final authority; it does not address how much of the flying automation does, and it is a standing rule rather than a recent change.
What this means
Whatever the automation does, the rule names one person as the final authority over the aircraft and gives that person the right to break the rules in an emergency. A system can advise; it cannot hold that authority.
What it does not yet show
A long-standing US rule; it shows where authority sits, not whether airlines will seek fewer people in the cockpit.
What you can check
Open 14 CFR 91.3 on eCFR and find "is directly responsible for, and is the final authority as to, the operation of that aircraft".
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
