Re: ALTITUDE & COMPRESSION READINGS

[frankr]

What auldscott said would seem to be true. Except. Compression readings on the gauge are the pressures inside the cylinder AS RELATED TO pressure outside the cylinder—–not as related to the absence of air pressure as in outer space. In other words, the gauge totally ignores the ambient or barometric pressure. It doesn’t even know what the ambient pressure is. Now if you were to put the gauge on the moon and run a long hose to the cylinder, his theory may be correct. I dunno, nobody has come up with a hose that long yet.

Just my uneducated opinion.
