I would suggest that if you have to fly a visual circuit with constant reference to the altimeter, no matter what it reads on touchdown, then you've got bigger problems in your overall flying than what you're setting on the subscale.
How the hell do some of you people cope flying into unmanned places with nobody to tell you what to set!
Well, kind of....
If it's unmanned then you have to eyeball it/use some common sense based on terrain heights/RPS etc I suppose, and I agree this should be something that should be well within pilots' capabilities.
However, if it
is manned then that's probably because you're not the only one around. A/C flying within the cct without reference to an altimeter set to allow them to maintain the correct height will
always put them in the blindspot of aircraft at the correct circuit height. Some days they'll pop up and take you aback, other days you might not be so lucky.
As for QFE and QNH....well, in the circuit as long as you use them both correctly they're fine.
Elsewhere clearly QFE has its limitations.
