From: Looking for the signals square at LHR
As has been suggested, a PPL student would be somewhat confused by the clock reading 120ft at the end of the runway when he has yet to leave the ground. At this point of the game he needs everything to be as simple as possible and "zero" would be an obvious logic but having acquired VFR height perception from circuit training, surely he has no further need for the QFE which he should be weaned off as soon as possible, in my view.

What I don't understand is why the transport people (and China) would use QFE. Has to be irrelevant - doesn't it? Descending to altitude from FL will put you on QNH and from there you might just as well use your inside leg or any other arbitrary unit of measurement providing the ILS is operating with the same units. "Descend and maintain 2,500ft to intercept localiser for 21 left blah blah blah" is never accompanied by "QNH" or "QFE". Why would it need to be? So where does the QFE come in?

BelArgUSA - not sure what I can do about hospitality but I do like your aircraft; particularly the DHC1. I flew a Pitts S2 recently and whilst it is of much higher performance, I would readily have traded it for the sheer flying satisfaction of the wonderful Chipmunk. I envy you.
