Where does it say in the POH that the aircraft will inter a spin from a coordinated power off stall in a specified configuration? This is a ridiculous conversation.
I'm not trying to pick on you, I'm trying to help you from experience, my friend.
Your last statement makes it much more clear. You were taught poorly yourself and don't quite have the "correlation" level of stalls, perhaps much more, down cold.
In all honesty, it probably isn't all your fault. This is what happens when the airlines start hiring at 500 hours, they get guys who were instructing for 6 months that didn't have time to become stronger instructors. It is a spiraling trend and even the FAA has noticed it. I thought I sucked as an instructor when I first started. I was another student who had come up in the great hiring wave of the late 90's-early 00's. I can't even remember a bunch of my instructors names....I just kept getting passed off beacuse the guy I had for 5 lessons got a job at XYZ regional. The time came for me to be a CFI, put in my summer of instructing (which I thought it to be more as paid time building), and guess what? Some ragheads changed the world as we know it 1 month after I found a job. CFI jobs became very difficult to obtain in the area I lived, there was no turnover because there was no airline hiring. And it forced everyone to become a better instructor, because there was always that fear of losing your job to someone who was better and knew more. The teaching part comes with time. Believe me, I ended up teaching for almost 3 years before the hiring lines opened back up. The knowledge base is something you have to have. And once you get to the instructing level, its on
you to know it.
Instead of continuing the beatings like the last guy said, I can only advise you to do what I did.
Get the Airplane Flying Handbook, the Jeppesen Private Pilot Manual, Aviation Weather, Private Oral Exam guide, PTS.....and go through them thoroughly. Make your self detailed notes and review them constantly. I'd give my students homework from these books all the time, then I'd do the ground lesson covering that material they were supposed to have read. This let me know where they were in the rote-understanding-application-correlation stages and allowed me to do my job in making sure they could correlate the material they needed to know. Another thing, some instructors like to teach the bare minimum to help the student pass the check ride. Try to go beyond this, teach your students all you can from the required materials and from your own personal experiences to help your students become better and smarter
airman.
I'd suggest reading the aerodynamics section of the
AIRPLANE FLYING HANDBOOK, then the entire thing as soon as you can. I'm not talking about the Cessna POH. This is a publication produced by the FAA and can be found at your local pilot shop, or online. And if you go on to get your CFII or Multi, I'd again advise you to spend the 20 bucks on the Instrument Flying Handbook and Multi Engine Handbook, and put in some time reading them and taking thorough notes. Better yet, you may want to get them even if you are not going to get those instructor certificates, you'll only increase your own knowledge and you'll be a better pilot. Smarter instructors produce smarter pilots.
Not to mention all the regional captains that will thank you for making their babysitting jobs just a little bit easier because their 400 hr F/O's will know just a little more than the last bunch that came through.
Good Luck.
