Does anyone change to QFE pressure to fly missions below 24,500 ft (which is when you should change to 29.92).

 

I've been flying the A10C RF campaign and noticed that on mission 2, Wags flies constantly at 29.92, even at 12,000 ft.

 

Just wondering what is actually the correct thing to do here so I stay in my altitude block.

Where does the 24500 ft come from, even in the US transition altitude is 18000. And the US is an outlier with having it so high and identical all over the place.

 

I just looked at a chart for Sochi (just to take an example) and the transition altitude is 3700, transition layer is 50. So yeah, you'd be at STD that high up.

 

Edit: Ok, missed the reference to Red Flag. Which is US, of course.

I imagine in reality AWACS or some agency will issue a current QNH for the area they are operating in so that when they go low they can dial the altimeter. I recall hearing some real-life Red Flag audio and AWACS was issuing QNH to the flights checking in.

If you're only going to be using a single altimeter setting then you should just set QNH prior to takeoff and leave it set. In the hog you spend 99% of your time below FL180 anyway so setting standard over Nevada isn't iften necessary.

I thought I heard that once somewhere - but on recollection it is the alt that all mil traffic comes under radar control service.
