I would like to hear from Babs on this one.


I'm trying to get her attention for her two cents.

Practically every government regulation in existence places an arbitrary limit to something subjective. Blood Alcohol content, voting age, driving age, age of consent, hearing damage, etc. With anything to do with safety the government usually has made the regulation more conservative as the result of some accident.

I mean, look at "seats in upright position". On the outside chance that you try and evacuate a plane, or for a small increase of the possibility of whiplash, they want your head 3" forward. Tell me what slows down evacuation time more, the seat head being angled back 3", or the reduction of seat pitch from 33"-34" to 28"-30"?

Why would you think that pilot fatigue laws would be any less arbitrary?

The thing about fatigue is you do not notice it until well past when it is affecting you. Hence erring on the side of caution.

There is a difference between merely being arbitrary and being both arbitrary and capricious.

Transiting a 0.8 DUI jurisdiction while most of your trip is 1.0 seems strange, but fatigue is hardly measurable and is not based solely on "hours" but is influenced by rest breaks, actual sleep, ambient noises, beautiful women in bars, quality of food, etc.

I had an instructor who kept giving the wrong Call Sign to the tower.... he had endured an overnight flight and was definitely fatigued.
I once saw a CHP car drive onto an exit ramp... hot, dehydrated, tired?

Usually there are safety factors but those margins keep getting eroded so why erode the fatigue margin. Keep it.
