What is one method to stop the tail rotor from spinning?

Using the bristle end of a broom as a method to stop the tail rotor from spinning is effective due to the capacity of the bristles to make contact with the rotor blades without causing damage. The bristles create resistance against the blades as they spin, effectively slowing them down until they come to a stop. This method is practical and safe, ensuring that neither the rotor nor the broom itself is harmed in the process, making it an ideal choice for this situation.

Other methods, such as applying brake fluid or using duct tape, can lead to potential damage either to the rotor system or to the components used in the process. Sandpaper is abrasive and would certainly damage the rotor blades if applied, which is dangerous and counterproductive. This highlights the importance of using a non-destructive and safe tool, like the bristle end of a broom, to halt the rotor while maintaining the integrity of the aircraft's systems.
