How do you think your ears would feel if they only started preasurization
upon reaching 8000'?

Of course, it won't work in a

pressurized airplane.



I've always been curious about this: Wouldn't the altimeter still read
an
increase/decrease in altitude? No, the altitude would not be correct
but
for a backup to keeping the shiny side up in IMC it would have some
value,
right?


My wife gave me one of these watches for my birthday. Its altitude is
pretty much dead one if I set it right in a non-pressurized airplane.

I took it on a B737 business trip, figuring that since airlineres are
pressurized to 8000 feet it should work up to 8000 feet, and it's at
those lower altitudes that I really wanna know how high we are since
that's when theymake you turn off GPS receivers and such. I naively
thought that the cabin was not pressurized until 8000 and then the
pressurization was turned on at that point to keep it constant.

Imagine my disappointment when on takeoff roll our "altitude" dropped
over 100 feet and stayed there until we were several thousand feet up,
only gradually easing up to 8000. Learn something new every day about
how airlines work.
