I am working on my CFI and while I was preparing my lesson plan on Aerodynamics and principle of flight I was questioning how much more should I teach to a Commercial student vs a Private student. For instance, how far should I go in teaching stability? Should the Commercial student know how draw out and explain the different types of stability and how the airplane acts in certain configurations? Versus a Private student; who I think should just know the difference between static and dynamic stability. Any help would be appreciated.
