The End!!
Thanks to the person who supllied a response to my simple question! I can't believe it led to all this! I think this draws this thread to a close. Cheers!
Below the Glidepath - not correcting
When there was a change or trial use of QNH in the zone in Germany in the early nineties (the exact details of which escape me) it was definitely confusing for both the controllers and the pilots to get QNH readback and then be given a confirmatory QFE. It really is what you are used to I suppose, but it is an obvious "Gotcha" waiting for the unwary. Having started the QFE way, but now being used to QNH, the latter does seems more logical (it also makes sure you get the aerodrome charts out and check the elevation every time). Mind you, being a rotary w@nker most of the time, it is largely academic when VFR.
I don't own this space under my name. I should have leased it while I still could
Two's In, as I said at the outset, this was no trial. The change was imposed from the very top against the strongest opposition from the pilot lobby, led by CFS and supported to some extent by the beanies.
Just think for a moment just how many documents are written around QFE. The easy ones of course were the Planning Documents but all the STARS, and every TAP plate had to be re-written and some airfields had a handful of plates.
Even before the door had stopped banging or the cleaner had polished the desk as CAS departed the process of switching bavk to QFE began. It took, if I remember rightly, rather less time to revert. I guess someone may have had a premonition and kept the QFE plates.

4Greens,
Along with the Missed Approach....all opportunities to incorrectly set the Altimeter are reduced when using the QNH method vice the QFE/QNH method.
In the USA...transition altititude is a standard 18,000 feet and below you use the QNH and above you use Flt Levels based upon 29.92/1013 settings.
All maps and charts show Elevations of pertinent obstacles and airports with a subheight indication showing Height Above Ground for obstacles.
For my view it matters not what the altimeter indicates during an approach or at touchdown...the number is calculated for me on the approach plate thus I don't even have to do maths as someone suggested.
If one cannot remember a single number array....from one to four digits long...he has not business flying.
All this argument stems from a group of folks that refuse to accept there is a different and better way to do things. After all, it you leave Blighty and go anywhere else in the world...you will adapt to the QNH system and have to revert to the UK system when back in the UK.

Getting hacked off now
Confucius - a few things :
1. Where is your evidence about E3 crew altimeter setting procedures ? - we always convert the figure if given in mbs (no mb option available on the altimeters)
2. I have been given an incorrect setting in inches (incorrectly converted by homeplate ATC), we cross-checked and challenged it.....
3. There is currently a stop-press at Waddo indicating that the FIH conversion table is indeed incorrect (we use either the ODM (or a crib from it) or our Nav system CDU which has a conversion calculator on it)...
oh, and another thing..
4. Why the unjustified mud-slinging, and what gives??
