I'm going to get stuck with some poor PPL student that deserves better instruction than I can give.
No, some poor student may be stuck with you, and yes, the poor student does deserve better. You're right about that.
Clearly. An admirable trait in a pilot.
As for your question I have no clue.
Again, this much is obvious.
It's obviously not a big deal if the 6 or so instructors I've had never told me about it.
Ah, well then. You've already learned everything, haven't you? If your six instructors didn't tell you, then you'll never need to know it. You've already been told everything you need to know, and if it hasn't been spoon-fed to you by these icons of aviation, then you really don't need to know it.
God help you if you ever fly anything more complex than a Cessna.
The learning process doesn't end with your six instructors. You're going to find yourself, if you last long enough, a student 20 years from now. I flew a 9 hour leg last night and learned before we started engines, and learned after we shut them down. If you think you know all you need to know based on what your six instructors told you, then you have a loud, very rude awakening coming. Get ready.
So far you've professed your knowledge of what's right or wrong with others instructing techniques (even started a thread about it, criticizing others), rambled about not needing to know anything your instructors haven't already told you, and in my case, wished I'd die and that my friends would die in airplane crashes...and you've managed to get one landing in from the right seat as a novice. How expert of you.
If you're seriously looking at becoming a flight instructor, where you lead by example, it's time to grow up, act a little more mature than a pissed off 14 year old, learn to behave professionally, and realize that you've got a LOT to learn.
People in this thread have taken the time to help you, and like most of your posts so far, you're too busy arguing to take what's given you and use it for your benefit. It's sometimes true that one can't give a drowning child a rope or a glass of water.
In the event you are not aware: you're the drowning child. Grow up, get out of the water and dry off. You're not in grade school any more.
