How much alcohol are we talking about here? Dies the viscosity of the
endolymph actually change?

yes. you can be quite sober and still have the viscosity reduction
active in your ears some 48 hours or more later.
never, never, never drink alcohol in the week before flying IFR.

do some serious human factors reading. the subject is fascinating.
our human sensations have some amazing limitations.

if you need a good introductory text on human physiology to get some
underlying understanding I can recommend 'Human Anatomy and
Physiology' by Elaine N Marieb. It is published by Pearson Benjamin
Cummings in san francisco. excellent!


I've got several physiology/toxicology text books but I can't see a
reference to _viscosity_ changes in endolymph with alcohol. Are you
sure you mean viscosity and not density?


Cheers

I mean exactly what I wrote.

human factors stuff is reasonably new. it is probable that the
research in the human factors work doesnt make it into the other text
books because it is fairly specialised.
btw I dont quote human factors books because I was taught this stuff
in my commercial pilot studies. it is standard modern australian
commercial level aviation knowledge.
