In a typical car steering wheel if you release it while the car is in motion, it will return to its center, neutral position.
What's the corresponding situation in an airplane? Is a yoke self centering? Or does it stay put until corrected by the pilot inputs? Let's stick to non autopilot modes to simplify the basic behavior.
The forces on the control surfaces ought to be high when deflected from their default position, right? So I'm assuming that offers a restoring torque? E.g. with the rudder if you take your feet off the pedals then it centers, I think.
Some additional points:
As a simplified case what happens on the ground when the aircraft is stationary. If I deflect the control surfaces to their extreme position & release the yoke would they all return to the neutral position? Is the restoring force gravity or spring loading?
The answers on the other question seem to focus on ailerons but what about elevators?
Does the rudder typically self center with more alacrity than the other surfaces? Why?
