In the highly unlikely event of of this ever happening again what's to stop someone simply powering down the satcom unit?
I suggest regulatory work will be focused on the root cause rather than the disease... no point knowing that a crew member has gone UDI after the event. Regulatory barriers need to be placed pre-event, not after the fact.
Does the civilian world utilize a pre brief risk matrix including health and personal stress factors? I know it sounds silly, but the guys we have picked up at work (Mil) with ilness type issues only emerged when prompted at the risk matrix assessment stage done during crew in. They wouldn't have raised the issue unless prompted.
I have seen risk matricies for things like CFIT Risk for Ops assessment
here
but am not aware if the civilian world has equivalents for fatigue and mental/physical health factors.
