So I have a friend going out to Red Deer Alberta to so some industial
air flow measurements of a sort. In his calculations he must enter the
atmospheric pressure. I thought, no problem, just get it from the metar
for Red Deer.

Red Deer is 3000 odd feet asl. If they are reporting 29.92 is the actual
pressure some three inches lower? But that is corrected for temperature.
Perhaps just use the pressure at the end, I think it is in Hectopascals
but is also corrected to Sea Level. What is the actual station pressure
he should use?

The volume of replies is stunning... I suspect the gang smells a
troll...
However I am full of the milk of human kindness this AM... So,here is
the answer:

Kindly purchase any version of the private pilots exam preparation
book or CD, such as that from the Kings, et. al. and all your
questions will be answered...
