Currently only the Private, Instrument, and Commercial PTS have been transitioned to the ACS. The FAA intends to transition the instructor PTS documents to the ACS in the future. Because the instructor checkrides are still based on their respective PTS, our lessons are still based off the required information in the PTS. With that said, we have done our best to make sure the information transitions between the PTS and ACS, and have added the ACS skill standards to each maneuvers lesson (i.e. steep turns, slow flight, etc.) so that you, and the student are aware of the different requirements.
We also developed the ACS Review eBooks to serve as a bridge between the ACS and PTS documents. While the ACS Review eBooks are not formal lesson plans, they are a task by task and element by element review of everything in the ACS. They are more of a detailed study guide and are great for instructors to review with students, or students to prep for a checkride.
When the FAA does release the Instructor ACS documents, we'll transition your lesson plans to the ACS free of charge.
