quote: Basicly the fact that there are no proposed F9 changes for it to meet the CC requirements means that its design was to Human flight or better safety standards. But these standards are saftey not mission assurance.

Note is that Atlas V does not meet these safety requirements and the avionics had to be upgraded including new additional engine monitoring, engine controllers, and software to meet the safety requirements. The F9 already had the monitoring, redundant engine controller (single failure operate dual failure safe), and software to implement the engine out capability. All of which is needed for a human flight. Only some possible software additions for performing abort notifications or additional engine status info to the spacecraft.
