If you are like me and actually plot out your routes with STAR/SID charts you probably understand this already but for those wanting to get into incorporating STAR/SID charts into your FPL you need to learn some important items. Section 3.1 will teach you what the symbols mean.
This link will explain how to understand altitude instructions on SID charts. This way you can follow real life altitude restrictions for Non-ATC controlled airports. Disclaimer When ATC is present all altitude clearances by them must be obeyed, regardless of altitude restrictions.
