IvanK Posted January 17, 2009 Posted January 17, 2009 Just flying some of the High Altitude Missions that come with BS. Why are the designers and devs working with QFE rather than QNH ? The manual only ever refers to QFE as well. When it comes to thrust limits hover ceilings etc I would rather have the Altimeter set to QNH rather than QFE.
miguez Posted January 17, 2009 Posted January 17, 2009 That's because in Russia commercial and military aircraft only fly using QFE. Even international aircraft flying in are only given QFE settings. The designers are just being realistc ;).
geogob Posted January 17, 2009 Posted January 17, 2009 That's really strange... especially in regions with mountains. That means you have to calculate the mountain top elevation and ceilings with reference to your field elevation? I'm not even sure I can do that on my CR-3. I'll have to figure out a way to quickly do the conversion on the fly. Any hints?
Frederf Posted January 17, 2009 Posted January 17, 2009 I would think that realistic travel in Russian aviation: Near Airport: Use QFE for that airport En Route: Use QNH for the region Above: 18,000ft Use 760mm Hg setting Personally I note the setting of the altimeter on take off and apply the QFE setting when operating out of that airport but once I'm clear of that airspace I set the altimeter to the proper barometric setting (or to match the ABRIS alt) and then fly normally. When I return to the airfield's airspace I set QFE again.
