qnh question

Recommended Posts

hi when doing a flight using rc4 i set the qnh given by atc, im flying in the uk my transition level is 6000ft, after crossing 6000ft i put the standard qnh in as 29.92ins, is this the correct procedure as i keep getting a message that my altitude setting is wrong press b to set correct altitude, which i usually ignore, also if i ask atc for a altimeter check after 6000ft atc gives me one thats different from the standard setting of 29.92. is this as things should be. thanks newbie

Yes, it is. Once you are above the Transition Altitude, you should have standard pressure on your altimeter sub-scale. You might like to note, though, that in the UK, we express this standard setting as 1013.2mB but 29.92in/Hg is the same value....i keep getting a message that my altitude setting is wrong press b to set correct altitude, which i usually ignore...You're absolutely right to ignore it. It's just FS showing its American origin. FS ATC is so amerigocentric that it treats the whole world as if it uses the US system of an 18,000ft Transition Altitude. When RC uses the correct Transition Altitude for your location, FS thinks it's an error and puts up the message about the B key. You should not use the B key to adjust your altimeter when flying outside the USA because it's set up to work with the US sysytem and will give incorrect results elsewhere. Just keep doing what you've been doing and ignore it.Also, it's a simple matter to turn of this FS message if you want. In FS, select the 'Aircraft' menu and then 'Realism Settings...' In the top right of the window that appears, you'll see a check box labelled 'Display Flying Tips'. Uncheck this box and you won't get the error message again.Pete
