Does the yoke move when trimming a THS like it does when using elevator trim?
When I was type rated in the CRJ200 with hydraulic controls and a THS, directly coming from light aircraft, the differences in technique are significant and it was definitely something new to learn.
With a THS, column neutral is always the same spot.  This means trimming to a speed is not a case of moving the control to location X and trim until it stays at location X. You have to apply a control input to achieve a speed/attitude, and trim until you can relax the control input and let it go back to its &quot;permanent&quot; neutral position while the airplane maintains the target trim speed.
So what you do is, say, you want to slow down from 200 kts to 180 kts, so you pull and hold to slow down. While you're holding the input, you start to blip the trim switch with your thumb as, at the same time you let the column move a bit back toward neutral.  The objective is to make the trim input as you relax the control input so that the stab incidence change is replacing the elevator deflection and the airplane holds a constant attitude and speed.
You keep doing this; blip-release-a-bit, blip-release-a-bit, blip-release-a-bit, until the column is back at neutral and the plane is holding your target speed with no input.  With practice you start to pull and blip the trim right away and it all just flows automatically.
It's murder on the trim screw jack drive systems, because they get many many start/stop cycles a flight from pilots going blip-blip-blip on the switch whenever they are hand flying.  The autopilot also does the same thing, sending numerous trim pulses to trim out speed changes to offload the AP drive servo.
Light planes with trimmable stabs, like the Cessna 180-185 family, are very similar, because the elevator just wants to &quot;trail&quot; when hands free, and the neutral position doesn't change the way it does with a tab, although it varies a little compared to a jet with hydraulic controls.
