In an earlier post I commented that in the QF72 incident the use of a geometric mean (1) instead of the arithmetic mean when calculating the aircrafts angle of attack would have reduced the severity of the subsequent pitch over. Which leads into the more general subject of what to do when the real world [...]
I tend towards the integrative rather than reductionist view of engineering and science. I'm interested in emergence, networks, relationships and interfaces as they apply to safety.what are the facts?
