And in certain situations, you can apply enough aerodynamic load on the stabilizer with the elevators to lock up the jackscrew that serves as the actuator, at least with the amount of torque the crew can provide with the trim wheel. The electric motor on the jackscrew can provide significantly more torque and is basically impossible to lock up, provided the jackscrew is properly maintained.
The issue is, the crew is supposed to overrule the electric motor by holding the hand wheel. This should be implemented by electronic torque limiter in the electric trim motor assembly.
But I have no idea about the specifics there - does it only work on the manual control wheel?
