After instructing for 8 months I can honestly say that due to the last 2 months of just time building with students, my knowledge has decreased more than I like. I remember my first students and how I busted my ass to know every damn reg and rule. Does anyone else feel like after a while unless you keep up that motivation, that the knowledge begins to dwindle away. I guess it was bound to happen after burning holes in the sky with the sole purpose of building time... although now that I look back on it I probably should have quizzed my students as we flew. I kinda feel like "that guy" who I didn't want to become when I first started instructing.
I know 100% about how you feel. While I still try to help students (I fly with a lot of kids who aren't mine on simple XCs or night flights etc) as much as I can when I'm actually getting paid for it, my knowledge base goes out the window. It's hard to get the motivation to get going again. I just recently had my 1 student get through the Instrument course without any trouble, but it took some effort on my part to get the explaining done. I feel that I can teach well in the airplane, but the book stuff is my weak point.
One thing that I was never the least bit confident on was aerodynamics...nevermind teaching it. I've never had anyone sit down with me (even during CFI) and teach me Aero and how to teach it. I've taken the class on it in school, but it was bare minimum...know it for the test and dump it. I can get through the basics, but it's tough to remember EVERYTHING if you're flying with Private, Instrument, AND Commercial students.
It's usually the WHY questions that get me. As well as HOW things work. I'm more of a reader, and I want to see things -officially- written down and shown with pictures of how they work. Then I can relate that information to students.
I still use notes when I teach lessons on the ground too. I could never get up in front of a student or group of students and just teach something. I was always a good student myself and got good grades but was never much of a teacher. I envy those who can do it well.
I'm probably saying this because I'm a part-time instructor while going to school. I earned my CFI through a "Fast Track" program with the school a year and a half ago. Since then I've signed 1 person off and thats it. All of my teaching has come from XCs, night flights, landings flights, and stuff like that. The ONLY airplane the school lets us lowly part-timers fly is the C172 even though I've got an MEI. Should I end up with a multi "upgrade" I know my motivation would hit the ceiling.
I'm guess I'm just tired of ended up in the practice area over and over again. And to be honest, I've become extremely complacent. When the time comes for me to do something new though, I'm game on. There's only so many times you can stay in the pattern in Daytona and not get bored out of your mind. Dangerous? Not really, but safe? Not really either. When I fly now in the 172 though, the checklist and the airport diagram (unless I'm not familiar with the airport) go right out the window.
Sorry for the life story and to be a debbie downer, but I think I'm just burnt out. When it all comes down to it though, all I need is 200 hours between January and May, and I will be at 1000/100. Will there be jobs? Maybe, but I've got something sort of lined up.
