Altimeter query.
-
QFE operations are largely a thing of the past. It was popular with the Soviets, RAF, and several commercial airlines (being the latest examples I know of). As a practice it required less brain work at the expense of less true understanding of the situation. Like setting your watch 5 minutes fast to trick yourself into being early it’s only a matter of time until a mistake is made by lying to yourself with the instrument. While it takes more information held in the mind at once it’s more or less resolved worldwide QNH is superior to set the altimeter as close to truth as possible and accept having to think about more numbers. Due to the fun that is altimetry a plane flying 5000’ MSL above a 100’ elevation airport and a plane flying 4900’ on a QFE setting aren’t exactly equivalent, although in practice they’d be close. But the merits of QFE v. QNH operations aside the supplied approach plates, most if not all air forces that fly the F-16, and if it was modeled in more detail the airplane itself is predicated on QNH operations (I think the takeoff roll does an A-CAL snapshot which relies on the altimeter to read as close as possible to true or maybe that’s just the A-10).
I’ve never seen a QFE-compatible approach procedure and would be interested in seeing one.

Ice, you’re perfectly correct,no argument. Use all tools.
“What airbase was home plate”……while my query was generic to the context, I just happened to be using Choongwon.
As you will know the DME arc moves over very undulating ground and both altimeters will vary in read out.
Thanks for your input.Bayonet.

Though these charts are almost 10 years old, an example is that Sheremetyevo, Moscow, Russia used QFE (unknown to me if they still do) alongside QNH.

Yes, it still use QFE
