FS2020 is the first simulator Ive played and on a whim Ive been using an add on pack call "FS Academy VFR/ IFR" to learn IFR. It's ok although the PDF manual needs editing because it throws acronyms at you without defining them so I find myself googling terms like VOR, NDB, OBS, etc. Thanks for your comment regarding X Plane's better IFR realism I'll be sure to check it out next. I enjoy "programmatic and calculated flying" a lot more than I expected, it's a shame FS2020 doesn't encourage it. I think the Hacker News crowd would enjoy this type of flying if they knew more about it. It also makes me feel a lot safer knowing how meticulously pilots have to plan everything. I dont plan on getting an instrument rating but the basic IFR knowledge made me a lot more confident with regular VFR flying because I feel better calculating descent and turns banks rather than just "eyeballing and feeling" them. I got much better at landing than with the in game tutorials to the point where I want to get a PPL.
