Well.......my observation is, whenever the rhetoric about "investigating all fatigue calls" raises it's ugly head it only means that more guys are "getting it", doing the right thing, and calling fatigued when they are. The FAA has ruled that "naps" are not allowed in the cockpit......Sooooo, maybe a pre-flt question should be, "are you rested enough to fly this segment w/o a nap"? If not then you should call fatigued. GUYS!!!!!! This horrible enviornment of onerous sequences WILL NOT STOP until we stop it. If you are fatigued.....make the call.
