I bought these lesson plans to help me with making my own. I don't plan on printing out all 700 pages for my CFI binder. But these lesson plans have helped me figure out how to structure mine properly and what information needs to be added. I go through every single section and take out any information that I feel is important enough to keep on my own lesson plans. That's why I love these. There is so much information in every single lesson plan that I can pick and choose what is important for me. The structure is in line perfectly with the CFI PTS too which helps tremendously. Every page has a hyperlink to help jump to different pages in the massive document and spend less time scrolling. I absolutely recommend these to any instructor in training and I'll definitely buy these again when I start working on my CFII and MEI.
Also keep in mind, I have not been through every single lesson plan yet so take what I say with a grain of salt. Based on other reviews from other pilots, these plans are properly fact checked. And from what I've seen, they copy a lot of the PHAK and AFH word for word and outline it in a better way with a few added details. Nevertheless, still a great value!
