Hi all, I fly the 767 by Level-D almost exclusively, and when hitting my transition level of 18,000ft and descending, by procedure I reset the alimeter (using the "b" key) to my destinations airport reading.My question is, in the sim I notice that the altimeter can change multiple times - high and low - of the reported A30.12 (for instance) while coming down through my arrival. Does this usually happen in real life? Using the "b" key to autoset the altimeter may not be prudent? Sould I set it manually, then not have to worry about the fluctuations? Just wondering what happens in the real flightdecks.Thanks!Neil :)

Hi Neil,Yes, it can and does change in real life although of course we don't have a "b" key or "autoset" feature and you won't notice such changes :) While on your approach as you descend below 18K you should be using the arrival ATIS pressure setting and/or as provided by ATC, then leave it until instructed otherwise or until changing to an alternate destination, where you would use THAT setting instead.Best,

Thank you very much sir!!Neil :)
