Ladies and Gents,
a question of trivia I know but,
during a descent from FL whatever, when cleared to 4000ft for example, we set the QNH (Mil QFE) depending where, when or what your'e descending for.
During a climb however, I thought I had read that once cleared to a FL setting standard was ok (regardless of your height/altitude in relation to transition level). I do remember reading this somewhere and also remember reading in days gone by that within 2000ft or so of transition you could do the same, I now believe that to have been superseeded by the "when cleared to a flight level set standard..."
In the big scheme of things I fully appreciate that its trivia but the're is always someone trying to prove you're wrong and there right...so ultimately the question is does anyone know the facts legal or otherwise and where it is written down...Thanks
