Pinefang Posted December 20, 2013 Posted December 20, 2013 Today I was watching a DCS you tube video and the pilot called inbound for landing and the QFE given was 3857. How is that even possible?
Flagrum Posted December 20, 2013 Posted December 20, 2013 Today I was watching a DCS you tube video and the pilot called inbound for landing and the QFE given was 3857. How is that even possible? The value looks like it was given in Pa (Pascal) although this seems a bit odd... What video was that?
Shaman Posted December 30, 2013 Posted December 30, 2013 You were watching A-10C video and QFE was given out by ATC in inches of mercury (inHg) not in hectopascals. 51PVO Founding member (DEC2007-) 100KIAP Founding member (DEC2018-) :: Shaman aka [100☭] Shamansky tail# 44 or 444 [sIGPIC][/sIGPIC] 100KIAP Regiment Early Warning & Control officer
Nealius Posted December 30, 2013 Posted December 30, 2013 38.57 inHg is beyond the realms of reality. The highest pressure ever recorded in the entire world was 32.06 inHg.
AlphaOneSix Posted December 30, 2013 Posted December 30, 2013 You misunderstand, that's the setting that goes into the Kohlsmann window on the altimeter to get the altimeter to read "0" at the airfield. It is not a "real" pressure reading.
Eddie Posted December 30, 2013 Posted December 30, 2013 You misunderstand, that's the setting that goes into the Kohlsmann window on the altimeter to get the altimeter to read "0" at the airfield. It is not a "real" pressure reading. While you are of course correct, it still means that the air pressure in the mission was so high as to be beyond the realms of the possible. If it were a lower than standard pressure then it'd just mean the airfield in question was at a high elevation, but a higher than standard pressure would mean, either, an airfield below sea level or high atmospheric pressure (or both). I haven't had time to do the maths, but I'm not convinced there is an airfield anywhere in the world low enough for such a high QFE. And a quick test in DCS show that the highest the air pressure can be set to (with standard weather) is 790 mmHg (31.10 inHg), and there are no airfields below sea level in DCS. So I can't even figure out how a QFE of 3857 is even possible in DCS, unless someone had used dynamic weather and manually entered the pressures. Of course that ignores the fact that ATC shouldn't be giving QFE anyway, or at least you should have the option to request either QFE or QNH.

It is not a "real" pressure reading. QFE is still dependent upon a real pressure. You would have to be something like 7000 feet below sea level to get a QFE like like that.\ Sniped by Eddie lol.
