Probability of technical occurance against probability of successful outcome is surely all that counts - no?
Entry to autorotation for a clean and unambiguous power failure on instruments is trivial. More complex failures however may well not be trivial in terms of workload.
Is anyone pretending that twin engined duplex systemed aircraft are not forced to land (relatively often perhaps - uncollected data)?
It's only good for safety (over cost) if it is actually safer?
How wrong are these points?
AND incidentally since most accidents are pilot error surely the major reason to have 'duplex' pilots is to reduce their combined error rate NOT just to spread the workload of an over-burdensome design?
