The Aeronautical Information Manual (AIM) is a "must read" book for private pilots, but it also contains a wealth of info that is interesting to the sim pilot. And other things that are just interesting, in a geeky sort of way. For example, from chapter 1 on "Navigation Aids":
(a) Certain propeller revolutions per minute (RPM) settings or helicopter rotor speeds can cause the VOR Course Deviation Indicator to fluctuate as much as plus or minus six degrees. Slight changes to the RPM setting will normally smooth out this roughness. Pilots are urged to check for this modulation phenomenon prior to reporting a VOR station or aircraft equipment for unsatisfactory operation.
Isn't that fun and interesting?
