Guest xny556 Posted July 12, 2003 Share Posted July 12, 2003 We all know that QNH is mean sea level pressure, but what do the 3 letters mean as an acronym..... Link to comment Share on other sites More sharing options...
J.O. Posted July 12, 2003 Share Posted July 12, 2003 It stands for Atmospheric Pressure (Q) at Nautical Height. The other option is QFE which is Atmospheric Pressure at Field Elevation (altimeter will read zero on the ground). Try the link to a site with a huge acronym directory. J.O.

Guest YVR_A320 Posted July 12, 2003 Share Posted July 12, 2003 The 3 l;etters don't stand for anything. They are part of the Radio operators "Q-CODE" http://www.booty.demon.co.uk/metinfo/QcodeMET.htm For more info do a search on the Q-CODE. Amateur radio operators as well as the military still use them. Link to comment Share on other sites More sharing options...
Moon The Loon Posted July 12, 2003 Share Posted July 12, 2003 I have to agree with YVR_A320 below. The Q Code has been around for much of the twentieth century and has its origins in Morse transmissions. _ _ . _ being the attention getter. As an interesting side note, Air Canada was the last transportation operator (air/land/sea) in the world that required crews to know the code. Do you guys still require new recruits to do "The Test"?

Guest xny556 Posted July 14, 2003 Share Posted July 14, 2003 This Q-codes have nothing to do with QNH.. Link to comment Share on other sites More sharing options...
Guest xny556 Posted July 14, 2003 Share Posted July 14, 2003 We have a winner....DATABUS. now what does it measure this QNH model measure... Link to comment Share on other sites More sharing options...
Innuendo Posted July 14, 2003 Share Posted July 14, 2003 Well my understanding of the Q code is that it was a way of minimizing the size of transmissions and messages hence the "codes", to save air time and message length. The list in the site gives their code meaning. QNH may have some technical meaning other than that listed in the site that you are looking for but I don't know about that. The definition in the site of QNH as opposed to QFE would essential knowledge when you are operating in an area where altimeter settings are issued for both. I'm not sure that QFE is that widely used anymore but obviously, if you got it mixed up with QNH it could be serious. Link to comment Share on other sites More sharing options...
