I was waiting for someone to say that. Educate me.
What he’s saying is, the elevator on most singles is more effective in propwash, for one.
So how do you know you didn’t “trim for stall”? Only set the trim at full power in a climb and never more?
Two, more elevator effectiveness with speed. Go out sometime and trim for best glide. Then give the yoke push and let go. Watch the nose hunt up and down with speed changes for a bit. This is covered in the AFM under types of stability.
In the end, you just have to put the aircraft where you want it with the controls and then you can trim away forces. But any change in pitch or power will upset the speed, and the aircraft trim state may cause the aircraft to “over do it” trying to find that speed.
We also see this in so called “falling leaf” stalls. Angle of attack increases and aircraft slows, control authority disappears and full rudder is needed until the nose falls and the aircraft tries to fly again — while always headed down.
In my STOL 182 I can do falling leafs not just with the trim all the way up, but with the elevator held all the way back. I demo this for folks by wrapping both arms around it. Don’t want aileron use anyway, so both arms around it, it’s full aft and not being turned. The airplane will just slowly bring the nose up, fall off, speed up, nose rises as elevator becomes more effective, wing stalls again or nearly so, repeat. The elevator is in the fully locked up position the entire time.
Make sense?
