The complete curriculum flight instructors actually use, from a student's first lesson to their checkride.
Not a summary of what a CFI teaches, the actual course: the same ground-school material used to take a new student from first lesson to checkride, in the order a real instructor would teach it. In development, handed over by Mach 9's own CFI-designed curriculum rather than written from scratch for the site.
This is a real, paid course, not a placeholder: the ground-school curriculum itself already exists and is used to teach students today. It is being brought over to Mach 9 and will require payment once it opens here, the price has not been set yet. Chapters and lessons will appear below once that happens; there is nothing to open before then.
