All the FAA really needs to do is create a "no fault crew fatigue" policy. If you are tired, call in and you would have no disciplinary action. I think any other kind of regulation on this issue is gonna be so subjective as to be completely useless. Everyone knows a 12 hour day with solid weather and 6 approaches is far more tiring than a 14 or even 16 hour day with clear blue skies.
-I can think of a couple of 12 hour days when I probably would have used such a policy.
