This is a masterpiece, it offers you both entertainment & education at the same time.
All information provided is based on the real life things. Even though i would say it's not 100% accurate, but you will still get insight about the aviation world.

Currently, i'm studying aviation stuff as my lecture focus. This software helped me a lot because i got early knowledge about the basic aviation theory from it, like common aircraft parts, aerodynamics, etc.

FSX will give you a better way to expand your aviation knowledge, rather than reading related books :D
