I'll not bore you with the details, but last week I was flying between the downwind leg and the runway, but in the "wrong" direction, at 800 feet (QFE) while a Typhoon who was downwind was heading towards me at 1,200 feet (QFE) just a little to my right.
It's quite common for us to be in mixed height circuits, and going in different directions. It all works rather well on QFE.
I suppose we could just learn to fly at 839 feet or 1,239 feet (or 539 feet for Helicopters) but I don't want to be looking for a 39 foot mark on the altimeter.
As for landing, I don't normally look at the altimeter after 300 feet in the descent, by then I'm looking out the front.
