None of them do, the horizontal component of lift turns the airplane. Private pilot knowledge, it's even on the written.
If you fire the lateral thrusters on a forward moving space ship, does that make ithe ship turn?
A force causes a linear acceleration, yes. But unless it's applied directly through the center of mass it will also cause an angular acceleration. In a constant rate turn, however, the angular acceleration is zero once the turn rate is established; then the sideways linear force is all that's needed to maintain the curved flight path.Not true. If you fire the lateral thrusters on a forward moving space ship, does that make ithe ship turn? A force will cause a linear acceleration. Turning requires a rotation about its vertical axis. In other words you need an angular momentum.
So you’re saying you flew that approach without elevator, also know as pitch, control?Years ago I did a flight review when the instructor gave a simulated locked stick. I was able to fly the plane and make an approach to landing using only power, rudder, and trim.
Space ships are not flying. They are in a vacuum. You put a thruster on an airplane it will not respond the same way as your spaceship.Not true.

Yep, elevator. No need to watch further. More properly, the elevator/horizontal tail surfaces together change direction of flight. If you could throw a switch to turn off gravity, a properly trimmed airplane will start turning, doing 360s in a vertical plane. Gravity just keeps it from happening during straight and level.
Yes.
Oh. Was it rudder or aileron trim you were using?Yes.

The wing's horizontal lift component gets the airplane moving into a turn. The tailfeathers get the fuselage lined up with the direction of flight, and both rudder and elevator are involved. Elevator is also necessary to counter the nose-drop caused by the turn's increased induced drag. The rudder can also contribute to that drop.
All the controls do all the work. It's an old argument. Another is the power vs. pitch argument for speed and altitude. You try to separate them and you just create confusion.
Flat turns use prop thrust and fuselage lift/drag. Good way to die in the pattern.
How would you describe the aerodynamics of the airplane in post #3 which is clearly able to turn, climb, and descend without an elevator? Hint: It has everything to do with stability and nothing to do with an elevator.Except, the center of mass is nearly always in front of the center of lift. So when the lift vector is tilted, then the angular momentum will turn the nose in the wrong direction.
How about that. Many pilots did that back in the BirdDog days. You can stick your arms out both windows and double the aileron effectiveness.If I stick my arm out of the Ercoupe window, the Ercoupe turns. Is my arm a control surface?
Cheers
And your point is... what? If you want to turn faster, take off the lock, bank the plane and use the elevator to lever the wing around. The wing has a much bigger surface to deflect the air, so why would anybody ordinarily use something else, not that it would be impossible to accomplish to a much lesser degree?I can put a control lock on the yoke to keep the elevator from moving, and can still get the plane to turn.

I thought the turn signal enables you to turn.

Lesson #1: if the controls feel funny, shut down and get things looked at. Do not take off. Optimism cannot create safety.this is from last summer.

Not quite. The center of mass is in front of the wing's center of lift, but in level flight the center of mass is exactly at the entire aircraft's center of lift, otherwise it would be accelerating in pitch.Except, the center of mass is nearly always in front of the center of lift. So when the lift vector is tilted, then the angular momentum will turn the nose in the wrong direction.
