Sasless, isn't the difference between the machines you listed and say a 350B3/407 maybe the workload in the cockpit for the single pilot in difficult circumstances or maybe even more importantly the expectation created? Is modern technolegy maybe hiding individual shortcomings during training which technolegy can not cope or compensate for in a real situation? The only way I see past this is objective sim training testing us under the circumstances that killed most of our fellow HEMS aviators and having the right to say somebody is restricted without being pressurized. Training teaches a lot, but there are certain life skills(decision making, situational awareness, responsibility, gut feel, etc) required when all turns pear shaped that can not be teached but must be identified before me as a individual can work and improove those skills lacking.
