FFF, I'm still only half way through the PPL so admittedly am no expert yet, but is it really true that people don't bother setting 1013.2 when over the transition altitude?
All I've been taught/read so far is that the transition altitude/level ARE adhered to and that the quad rule for selecting a flight level is very important too. Is the real world different? I guess the problem of learning it all from a book is that you have to learn the 'real world' stuff later from experience.
Most of my flying is within an AIAA, and I don't fancy being out by a couple of hundred feet with all that low level, fast moving traffic.
Thanks
