I am just starting to learn (practice) some basic IMAC. I'm having some trouble finding explanations for some real basic stuff like what different symbols mean and how something like the Basic Sequence is flown. So here are a couple of starter questions.

1. Can someone give me a link to a site that will answer the first part of my question: i.e., symbol explanation.

2. What does it mean on a Sequence Chart when a dashed line connects some of the maneuvers and not others; i.e., #2 to #3, but not #3 to #4, etc.

thanks.
