A Category 2 drone must not cause injury worse than a rigid-object impact of how much energy?

11 foot-pounds of kinetic energy.

  1. 11 foot-pounds ✔
  2. 25 foot-pounds
  3. 55 foot-pounds

Why: Category 2 drones must not cause injury equal to or greater than a rigid object transferring 11 foot-pounds of kinetic energy. They must be listed on an FAA-accepted declaration of compliance.

Huh, didn't know that: Category 2 drones must also be labeled as eligible for Category 2 operations.

The dad joke
Why did the Category 2 drone take a gentle approach? It did not want to make too big an impact.
