Overall, I'm really happy with the CFI Lesson Plans. There is only one item so far that (for me, at least) could be improved:
Technical Subject Areas II.C and II.D seem disorganized and out-of-sequence with the PHAK textbook. Many elements of II.D should come before II.C. Instead of II.D, being referred to as Additional Info, I would prefer to see these two lessons reorganized and broken up into part 1 and part 2. Additionally, many of the graphics are outdated and have since been updated in the FAA's PHAK.
