ANFI
For example when mitigating engine failure risk (by using two engines) are the consequent additional risks factored in? (like: pilot closing the wrong throttle(happens), critical components having less margin, worse autorotation performance, more complex gearbox (malfuntions), reduced payload/utility, fuel system complications (eg the A109 in Wales)). Reliability of FMEA work? - is that factored in?
Reduced payload with two engines? Less margin on critical components?
What tosh you write.
