PF,
... why should an extensive traveller, who is not a pilot, be aware of blood/alcohol limitations ... anywhere?
I'd have thought it was useful to know whether you could have a beer or a glass of wine with your lunch wthout going over the legal limit for driving your hire car afterwards....
Anyway, 2dmoon and I just were trying to work out why the figures didn't line up, not the legal limit in Norway.
Legal limits for cars seem to vary widely, from 0 to 0.1% and everything in between. For aircraft I would expect them to be a lot less than the 0.08% or 0.05% which still seem to be prevalent in most countries.
Cosmo,
Strictly speaking I would have thought a "zero" limit would be unenforceable, because the body itself (digestion, etc.) produces very small quantities of alcohol. Men, women and children all have a natural blood alcohol level in the order of 0.003%, not "zero-zero".
