Hi,
I would just like to get an idea as to what is the hardest part of flying or what students have a hard time learning from an instructor's standpoint. This will help me prepare well before I arrive. Like I'm sure Instrument Flying is hard in itself. Is there anything else? Steep turns? Any flight concepts?
Since I will mostly be going on with my instructor ratings and then teaching, what should I keep in mind to become a first class FSI instructor and live up to the school's reputation
