The FAA Fail-Safe Design Concept and design principles or techniques for safe design are maintained. However, owing to the increasing development of Highly Integrated Systems in aircraft, qualitative controls previously considered necessary for safe software development are extended to the aircraft function level.

Once this task description has been constructed a nominal human unreliability score for the particular task is then determined, usually by consulting local experts. Based around this calculated point, a 5th – 95th percentile confidence range is established.
Task A: Diagnosis, HEP 6.0E-4 EF=30; Task B: Visual inspection performed swiftly, recovery factor HEP=0.001 EF=3; Task C: Initiate standard operating procedure HEP= .003 EF=3; Task D: Maintainer hook-up emergency purge ventilation equipment HEP=.003 EF=3; Task E: Maintainer 2 hook-up emergency purge, recovery factor CHEP=0.5 EF=2
Human-rating certification, also known as man-rating or crew-rating, is the certification of a spacecraft or launch vehicle as capable of safely transporting humans. There is no one particular standard for human-rating a spacecraft or launch vehicle, and the various entities that launch or plan to launch such spacecraft specify requirements for their particular systems to be human-rated.
David D. Woods is an American safety systems researcher who studies human coordination and automation issues in a wide range safety-critical fields such as nuclear power, aviation, space operations, critical care medicine, and software services.
In conjunction with ARP4754, ARP4761 is used to demonstrate compliance with 14 CFR 25.1309 in the U.S. Federal Aviation Administration (FAA) airworthiness regulations for transport category aircraft, and also harmonized international airworthiness regulations such as European Aviation Safety Agency (EASA) CS–25.1309.
