For just about everything in piloting has a procedure, sometimes a few procedures for the same operation, pick the one you like, but procedures, none the less. Aside from some avionics innovations, I can't really think of a need for a new procedure in flying a certified GA plane - it's been done before, someone has died doing it wrong, it's been refined and documented. Most established procedures are well described in training material. Frequently, there are reasons for these procedures, or limitations within them, which are not evident. So, curious pilots are out there trying things, because they don't know enough yet to realize the other factors in what they're trying, and how they are going to have zero safety margin if the slightest thing goes wrong, where otherwise, the established procedure has adequate, or the most available safety margin build in to it.
When I learned to fly (and the pedestrian means of recording was super 8 movie film), there were not too many stupid things being done in planes to be watched later - a few, but not many... So new pilots had less opportunity to get "ideas" from watching videos. We were happy just to fly the way our instructors taught us, and refine those skills as experience grew. Yes, we'd take on a stronger crosswind with more experience - but the procedure was still the same. We'd land shorter, but the procedure was still the same.
Now, we have endless videos, many, of pilots doing things which are outside the norm of procedures. Most of these pilots seem to get away with it (and then go and try it again ), perhaps never realizing how close they came to not surviving the first time. And, of course there are new pilots reading here, perhaps taking seriously what some posters postulate. That worries me! I have, during training, had to disappoint a few owner/pilots by explaining that no, they should not be attempting what their imagination presented to them. They just have not imagined yet why it's a bad idea! Thanks to the experienced posters here who will leap to point out that something may be dumb to attempt.
So, if you don't know, ask. If you know, but don't know why, ask. If you imagined up something different, and you have to ask, well... okay, but how about asking: "What is the really good reason that we don't do x instead of y?" There'll be a reason, and someone will explain it!
Happily, I have zero experience and qualification using flight simulator software on my computer, so I won't even speculate if some wild ideas about piloting originate there!
Edited to add:
Yes, I have and do practice pitch control failures - because the flight manual for my plane provides a procedure in the POH, which is FAA approved.How many do this? Is it ever taught in schools? Do YOU do this for every type of small A/C you fly? Have you practiced engine out 180+ degree returns to airport using an aerobatic procedure to accomplish the task?
Yes, I have landed an airplane with a massive pitch control failure, found during the maintenance check flight I was asked to fly.
Yes, I practice 180 degree gliding returns to touchdown, 'last one three days ago. I have not found aerobatics necessary to accomplish this, I just follow the POH procedure and my training. Demonstrating such power off approaches was a requirement for my helicopter license.
