- weaksauce 7y agoyou only trim with the wheel when the power is cut to the trim motors.
- tjohns 7y agoThe trim wheel spins like that anyway under normal operation, both due to pilot input and while on autopilot. More importantly, you don't grab the trim wheel while it's moving... If the aircraft is operating normally, you use the trim switch on the yoke. The only time you'd spin the trim wheel by hand is if you've had to cutout the electric trim motor... and once that's done it's not going to move on its own anyway.

- Doxin 7y agoThey teach pilots a specific way to grab the trim wheel for that scenario as to not break their wrists. It still can (and occasionally does) cause abrasive wounds to the hands however.
