The fact a professional organisation such as the RAF are still using QFE is beyond me. The claim that "remembering circuit heights" or "I want it to read zero when I touch down" are ludicrous. I, for one, don't look at my altimeter when I'm in the landing flare. I don't base my flare on altimeter readings, nor even much of my finals turn - I fly the plane.
Even if the circuit height argument was valid - what's the difference between the highest field elevation and the lowest here in the UK? A couple hundred feet? Make your standard circuit height 1500' and use pilotage in the finals turn to compensate...
What do you do when you go to the states and fly into places like Albuquerque or even Las Vegas? Let's not even talk about Leadville, Colorado at 9,927' field elevation!
QNH for fields in close proximity is far safer than QFE as all would be on the same setting.
I cannot get my head around the fascination with QFE...
