I have always beleived that the biggest ground proximity warning a pilot will ever receive is the altimeter winding down to zero, so I like QFE.
And if, as you go on to say, you fly the approach with QNH still set and you think you are looking at QFE,
you don't get that ground proximity warning. Which is precisely why QNH approaches have to be standard. I think you have successfully argued for a preference for QNH.
Add to that doubling the work in setting/crosschecking altis in the descent/approach, plus resetting on the go-around, doubling the possibility of mis-setting them all add up to the fact that I CANNOT understand why QFE operators (including the military) hang on to QFE.
