What it would appear here is that we have a few North American pilots, whom are so enmeshed in their 'good ole way of doing things', that they think they can out-think everyone, and can't comprehend what other pilots, in other airlines, in other parts of the world, have been doing for years, and all quite safely, in full compliance with their specific airlines SOP's....simply because the North American folks are perhaps far too arrogant to understand.
Gosh, why am I not surprised?

Interesting topic, I just had the same discussion with one of my F/O's. Do we set QNH when cleared to alt or do we have to wait for the TL?
In one way or another I was convinced that I read somwhere in the JAR OPS or other official paperwork that we can set QNH when cleared to a alt as long as no level flight above TL was to be expected. Now I do not find this 'evidence' anymore.
Can anyone give me a hint where to find this law/procedure/ICAO rec/....
(It's about a beer

Thanks

Not sure where your 'Dark Side' Ops are, but JAROPS requires JAR airlines to include such procedures in their Ops Manuals, and I don't think that would change with 'EUOps'.
Do you have such? They are written so that both you and your co-pilot will know the SOP altimeter setting procedure in contrast to our US colleagues who all have their own individual 'recommended' procedures, it seems.

- metric altimetry and conversion tables,
and
- QFE operating procedures.and

MineDog - for UK, you may find the following references helpful:
UK AIP, ENR 1.7
Note to table at para 6.3 of Section 1 Chapter 6 of CAP 493.
Hope this helps ... and if it does, enjoy the beer ...

UK AIP, ENR 1.7
5.1.4 Within Controlled Airspace a pilot should set one altimeter to the latest Aerodrome QNH prior to take-off. While flying at, or below, the Transition Altitude vertical position will be expressed in terms of altitude based upon the Aerodrome QNH. When cleared for climb to a Flight Level, vertical position will be expressed in terms of Flight Level, unless intermediate altitude reports have been specifically requested by Air Traffic Control.
5.3.1 When an aircraft is descended from a Flight Level to an Altitude preparatory to commencing approach for landing, ATC will pass the appropriate aerodrome QNH. On vacating the Flight Level, the pilot will change to the aerodrome QNH unless further Flight Level vacating reports have been requested by ATC, in which case, the aerodrome QNH will be set following the final Flight Level vacating report. Thereafter, the pilot will continue to fly on the aerodrome QNH until established on final approach. When requested by the pilot or local procedures require, the appropriate QFE and aerodrome or threshold elevation shall also be given.
