The argument can be readily settled, since aircraft altimeters are very precise instruments for measuring pressure. For the test, one takes an additional altimeter on board on the aircraft. It is not connected to anything. That altimeter is calibrated on the ground, before start of the engine, so that it reads exactly the same as the panel mounted altimeter. Then one takes off and records in flight whether the surplus altimeter reads higher or lower than the panel mounted altimeter. If the surplus altimeter reads lower than the panel mounted altimeter, then cabin pressure is higher than the pressure in the static line, and conversely. BTW, I was a bit bold in saying "always" about lower cabin pressure. This does not apply to pressurized aircraft, and there may be particular designs where it does not hold. But it seems correct for the type of aircraft we are concerned with here. Happy flying, Klaus ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message zenith-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Zenith-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/zenith-list Browse Digests http://www.matronics.com/digest/zenith-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
